Key Factors to Keep in Mind When Seeking Out a Piano Tutor
Key Factors to Keep in Mind When Seeking Out a Piano TutorAny student looking for a solid, working foundation in piano learning should seek out a high quality set of lessons from a qualified and professional teacher who can deliver the kind of results they expect. The ten key factors to keep in mind when considering a tutor are:The teacher must be flexible enough to tailor the lessons according to the student's progress and level of ability. They should know how to set a correct pace for the class, so that each student receives the same amount of time for all aspects of the lessons. They must not fall into the trap of teaching techniques that seem 'good' on paper but can actually be quite difficult to get used to in the classroom environment.The personal attention given by the tutor is a vital element of the teaching experience that every student should consider when seeking out a tutor. The ten key factors to keep in mind when seeking out a piano teacher include: Any candidate shoul d be well versed in the basics and basic theory of piano. The class should be set up in a way that will enable the tutor to discuss the music as it should be listened to and understood.There is no doubt that large group lessons are more effective than one on one tutoring. The single most important key factor is that the tutor is able to provide individualised attention to every student. Most students have certain areas of difficulty and are best helped to solve these problems, rather than going through the whole lesson without learning anything new.The student should have access to a program that not only provides access to a tutorial, but which also covers the basic concepts that they need to begin learning. In particular, they should be provided with a tutorial explaining the harmony between the notes of the piano. Most students will move quickly through some sections of the lesson and will require extra help to move to the next section of the lesson.The tutorial and the progress report that are generated during the lesson are two of the most important components of the instructional process. These factors should provide some idea of what needs to be worked on to reach a specific goal, as well as showing progress in terms of the student's ability to play a specific piece of music. Both factors should also be noted within the tutorial itself.The element of support from the tutor is often overlooked as the key factor in piano learning. Students generally do not feel supported and will move on to new piano teachers without assistance. All teachers need to demonstrate a commitment to help students reach their goals in a professional and reliable manner.Most students will move on to a new piano teacher after their first visit. This means that the ability of the tutor to help them learn to play should be measured against that of the initial session. The ten key factors to keep in mind when seeking out a piano tutor are: That the teacher is familiar with the genre and style of music that they are teaching, and able to provide feedback that the student can use to work through.

What Is Electron Configuration Chemistry?
What Is Electron Configuration Chemistry?The electron configuration chemistry definition is the concept of utilizing the various properties of electrons in order to create and design compounds that exhibit desired properties. These properties include that of being electrically neutral, non-toxic and non-flammable.An electrolyte is an electrochemical fluid with a positive electrode and a negative electrode. These electrodes are a common feature in the production of cathode materials. Cathode materials also include cathode salts, which are designed to hold electrons for a period of time, such as the metal zinc or the silver oxide, or anode materials which contain electrons and are used to hold the cathode until the metal material is oxidized.An electrolyte is used as a stand-alone substance, or it may be combined with anionic ions in the form of an ionic liquids, to have either 'electrically neutral'non-electrically neutral' cathode materials. Cathode materials in this class are utiliz ed as materials for batteries and power sources. Today the definition of the electrospray power sources for electrospray devices was extended. This device includes two electrodes, a negative anode electrode and a positive cathode electrode.The flow of electrons from an anode material to a cathode that has a low conductivity will cause the flow of source energy to flow from the power source to the device. Through this process, power can be generated and stored in batteries or other electrical devices.The electron configuration chemistry has led to the development of many complex chemical entities. A compound that exhibits properties similar to those of the commonly used compounds in chemistry is called 'electron friendly'. Many new compounds are created from these new properties. In the early 20th century, a compound is a compound that displays the same atomic weight as the base.A compound is not necessarily 'slightly different' than any of the base chemical components. It must displ ay the same atomic weight or more and display properties that are energy and/or structural change resistant. A compound is an 'electron friendly' substance.A compound is an electron configuration chemistry, and it will exhibit properties similar to those of an anion. If an atom in an anion is replaced by one of the electrons, the two atoms of the anion are not altered in size. It does not matter if the atoms of the compound are removed from the original or added back in place, the atoms of the compound are the same size, and they are still an ionic liquid.

How to Find Audition Songs Guaranteed to Make You Shine
How to Find Audition Songs Guaranteed to Make You Shine Suzy S. Need help selecting the perfect song for an upcoming audition? Finding the right song can take time and theres a lot to consider as you decide! Even if youre comfortable in the spotlight and dont suffer from stage fright, theres often a long, arduous process to prepare for an audition. As a professional vocal coach, I can share two secrets to making it all easier. In fact, these two things make auditioning downright enjoyable! First of all, treat each and every audition like a performance. Why? Because it is a performance! Approach it like you have the job already. Second, you need to select an audition song that best shows you off. But, how do you choose the perfect song to sing? Here are the 10 things I recommend thinking about as you look for the best audition songs. How to Pick the Best Audition songs Is your voice low and rich? If youâre auditioning for a band, you better leave the Beatles tunes at home (Paul and John were tenors, the higher male voice). What about ladies? Higher-voiced females auditioning for a band may have a harder time finding repertoire, as most commercial music features mid- and lower-voiced females, but it can be done! The best way to learn how to sing for your voice is to try out many different tunes. Any strain may mean itâs out of your comfortable vocal range. Your voice teacher can work with you on this, of course! Editors Note: Check out these ideas for audition songs for tenors, and audition songs for altos. Vocal competitions are considered auditions too, and sometimes they have very strict requirements. For example, they may have you sing a song by a particular composer or a song in a particular style. Make absolutely sure you follow these rules! Once youâve established what repertoire you can select from, the key is to choose a âcrowd pleaser. Letâs use classical music for an example, since they have many vocal competitions. At the world-famous Metropolitan Opera Auditions, they like âshowyâ types of singing. Mozart, with all of his vocal runs, trills, and leaps, is seen as very impressive if executed well. If youâre looking at a pop or rock competition, itâs a little different. Whereas classical world likes the tried and true, the best pop audition songs arent always the most current chart-toppers. The judges may be tired of hearing mediocre versions of Whitney songs or Hallelujah, also. Instead, challenge yourself and try a forgotten oldie or a song from the American Songbook. Musical theatre auditions usually require a singer or actor prepare 16 or 32 bars of a song, or two contrasting excerpts. In musical theatre, you must consider your voice type, but more importantly, your TYPE! Are you a funny girl? A leading man? The femme fatale? These are all critical factors in deciding on the best audition songs to show off your skills. One more thing worth mentioning: As prevalent in all genres, there are many overdone audition songs to avoid. Make sure you donât make that mistake. And donât automatically write off musicals that didnt do well at the box office they often have great music! Editors Note: Check out these top picks for musical audition songs, based on your voice type. Are they asking for a cut from a song, such as 16 or 32 bars? Some songs are much more awkward to cut than others. To avoid the awkwardness, choose songs that are fairly simple in structure (verse-chorus-verse, for example), rather than a song that rambles like a long musical monologue (think of many of the songs from âWicked, for example). Simpler is always better, if you have the option! These days, kids have great repertoire to choose from. The problem is that kids often go into competitions or auditions with songs that are inappropriate; either the songâs subject matter is too mature or the song is beyond their capabilities. When youâre looking at popular music, it gets especially difficult as most songs deal with romantic relationships. However, there are plenty of pop songs with positive messages. Look at the repertoire of Taylor Swift, Bruno Mars, or Rachel Platten. Kids can also do well by going old school. Young girls can look at the music of Connie Francis, and both boys and girls can sing a lot from the Lennon/McCartney songbook. If youâre looking at musical theatre audition songs for kids, be aware of whatâs overdone. No âAnnieâ ever unless they specifically ask for it. Get a good musical theatre anthology and explore the songs that you may be unfamiliar with. For kids, the main idea should be about confidence, personality, and fun! If youâre a novice singer, there are plenty of good songs out there for auditions! The Great American Songbook is a great place to start for commercial music singers. Classical art songs (not big, technically-challenging arias) are best for those new to the world of classical or opera especially for competitions. Try not to bite off more than you can chew. Youll want to choose repertoire that youll be able to sing fairly well, even on days that arenât so great (i.e. if youre sick or tired). But of course, the more you progress, the bigger your repertoire pool will be! Your teacher and other music professionals will be a big help in this journey. While theres quite a bit of freedom in what either gender can sing in rock, pop, and jazz, its not the same for classical and musical theatre. Iâll never forget the judges shaking their heads at a vocal contest when a young baritone sang âAddio del passato,â from the opera âLa Traviata. This is an aria meant for a light soprano! Heâd never perform that role on the stage, so thats why itâs not a good idea to present it in an audition or a competition! Editors Note: Take a look at these top audition songs for boys for specific recommendations. If youâre a shy, young soprano, it may be a challenge to do a sassy number like âAll That Jazz,â for example. Likewise, a character actor type shouldnât go walking in with a tenor power ballad that may confuse people! Know yourself and be proud to be yourself. Thereâs room for everyone out there young, old, funny, sexy, nerdy you name it. Playing against a typeâ will get you nowhere and youâll find you donât land the gigs you want! This is similar to selecting your audition song based on the required cuts, but also keep your audience in mind. Your audition panel has been listening to singers all day long and doesnt really want to have to cut you off. Singing a shorter song is fine, as long as it shows off what youve got! Less is sometimes more. The judges often know all they need to about a singer in a surprisingly short amount of time. Frantically learning a new song before an audition doesnt always work. If you have already found audition songs that show you off, by all means use one of them if it fits the audition requirements! Otherwise, there is more room for error (lyric flubs, weak high notes, etc.). I recommend that every singer maintains a book of the best audition songs theyve worked on, ready to go at any time. And finally⦠No? Then donât do it. Period. Your audience can always tell if youâre not into it. Since there are so many songs out there, theres no excuse for doing something you dislike just because it may fit your voice. You have to connect with all of your songs! Post Author: Molly R.

ChaptersWhat Should I Look for in Personal Tutors?Should I Interview a Tutor Before Hiring Them?Questions to Ask Your TutorHow Can I Ensure My Childâs Safety During Private Tuition?When it comes to private tutoring, both in person and online, there are lots of factors that parents will be considering before they hire someone.Youâll be considering a tutorâs experience and qualifications, their teaching background, references from current and past clients, and their general character and attitude.The absolute priority when employing a personal tutor is to create a safe, comfortable and positive environment for your child to learn. To find a tutor can be quite tough sometimes with so many things to consider, but itâs best to take the time to find whatâs best for you and ensure tutoring is worth the time you put in.Creating a secure and tidy study space is key to safe lessons at home! Photo via VisualhuntParents and carers must be vigilant and cautious when employing someone to work closely with a child, so here is our advice on how best to go about the process.Bristol tutorsLondon tutorsEdinburgh tutorsLiverpool tutorsA level tutorsShould I Interview a Tutor Before Hiring Them?The question of interviewing a tutor before you hire them is entirely up to you, but itâs not a bad idea. It can be as informal as you like, and doesnât need to take long, but could give you an idea of whether you would be comfortable with them working closely with your child.Don't hesitate to plan an interview or preliminary meeting with a prospective tutor! Photo via Visual huntYou can interview a tutor over the phone, but in person is always best if possible. If you are hiring an online tutor, a quick video call would do the trick to meet and get to know them a bit more. Although cost as a consideration should fall well below your child's safety it would be a good idea to speak about the cost of home tuition at this point as well.In an interview you will be able to ask any q uestions you have about the tutorâs professional background and experience, their qualifications, their education and to get to know them a bit more as a person.Try to ask positive and proactive questions that require a thoughtful response. When the tutor answers your questions, be aware of their tone of voice and observe their body language â" this can say a lot about a person. You want someone who comes across as friendly, open and approachable.An interview is a great time to make it clear where and when the tutoring sessions will take place. Decide on somewhere appropriate, tidy and easily accessible for both parties. As a parent, you can remain present during the lessons if you prefer, or simply leave the door open and check in sometimes.A suitable place to conduct tutoring lessons would be a study or dining table â" anywhere open and with a table and chairs. A childâs bedroom is not a suitable place to hold private lessons.During the interview or first meeting, trust your instincts as a parent and as a person. If something doesnât feel right or the tutor doesnât seem to match up to what you had in mind, or to how they had initially advertised, donât be afraid to end the interview or call off a lesson.Questions to Ask Your TutorSuggested questions to ask a tutor include:How much experience do you have?Can you provide a reading list?Which study books do you recommend?How do you measure progress?Do you provide periodic progress reports?Where do you teach?Do you provide online tuition?How many hours per week are usually necessary?Do you set homework?How many hours a week should I study/practice at home?Do you offer discounts for block bookings or concessions?Do you charge for travel?Do you help with other areas such as interview technique and CV-writing?How Can I Ensure My Childâs Safety During Private Tuition?There are naturally many risks involved when you hire a private tutor to conduct lessons in your own home or in theirs. There are many fa ctors you might want to consider, such as the health and safety risks involved, whether your tutor has any personal insurance, and if they have a DBS certificate or basic background check.Child safety is always the top priority when it comes to home tutoring. As a parent, you will want to do a few checks to ensure that you and your child feels safe with the arrangement.If you will host the tutor in your home, you might start by setting up a tidy space for the lessons to take place â" this can be somewhere that you can easily keep an eye on things. If your child will go to the tutorâs home, you can have a look at the proposed work area to check for hazards etc.It might be important to you that a tutor has personal insurance, such as public or professional liability insurance, which is something you can discuss with potential tutors UK before hiring them.Equally, you might want the tutor to have a DBS certificate or some form of background check for that added peace of mind. If you r tutor works through an agency, they will most likely have a DBS certificate.If your child is visiting the tutorâs house for lessons, there are a few ways to feel more comfortable and safe. If your child has a mobile phone, you can ensure a bit more personal safety by making sure they keep their phone on with the sound on.Never let someone pick your child up in their car. Always aim to drop your child off yourself or let someone you trust do this if you are unable to do so. If your child is old enough to travel alone, then make sure they have their phone on them.If your child has any allergies or medical issues, make sure you let the tutor know beforehand. It could be anything from pet hair to nuts, or more serious illnesses, but alerting the tutor will eliminate a certain amount of risk when you arenât around to supervise.Your child might receive their personal lessons with an online tutor via a video call. Naturally with online tutoring you don't need to think about hazards a t home, but you will still need to keep an eye on the lessons to make sure that everything runs smoothly and safely.Keep kids safe during their online lessons. Photo via Visualhunt.comYou can monitor your child's online lessons by setting up the computer in an open space in the house where you can supervise, or by leaving a door open if you aren't in the same room. You can also keep an eye on any files being shared between the tutor and your child for added security.Remember that with online tutoring, you can meet the tutor via a video call before starting any actual lessons so that you know how it all works and you can get an idea of what the tutor and their lessons will be like.If you have any concerns about your tutor or your childâs safety, you can find more information and help at the NSPCC website.
Volume of Rectangular Prism Tutors
Volume of Rectangular Prism Tutors A prism is a 3-dimensional closed geometric figure and a rectangular prism is one of the different kinds of prisms. A rectangular prism is a prism consisting of a rectangular base and all the surfaces including the bases are also rectangles. Since it is a 3-dimensional geometric figure, it consists of length, width and the height. Volume of a rectangular prism is the measure of the space contained inside the prism and it is equal to the product of the length, width and the height. Example 1: What is the volume of the rectangular prism whose length is 6.5m, width is 3.2m and height is 5m. Given the length of the rectangular prim, l = 6.5m Width of the rectangular prism, w = 3.2m Height of the rectangular prism, h = 5m Volume of a rectangular prism, V = (length) * (width) * (height) Hence, volume of the rectangular prism, V = 6.5m * 3.2m * 5m = 104m3 Therefore, the volume of the given rectangular prism = 104m3 Example 2: What is the volume of the rectangular prism whose length is 6m, width is 2.5m and height is 8m. Given the length of the rectangular prim, l = 6m Width of the rectangular prism, w = 2.5m Height of the rectangular prism, h = 8m Volume of a rectangular prism, V = (length) * (width) * (height) Hence, volume of the rectangular prism, V = 6m * 2.5m * 8m = 120m3 Therefore, the volume of the given rectangular prism = 120m3

Basic Geometry Equations and Examples Mastering Basic Equations of Geometry ChaptersThe Basic ShapesCalculating TrianglesCalculating QuadrilateralsCalculating PolygonsCalculating CirclesSome people might say that geometry is in no way a âsexyâ subject; really, as a general rule, calculating angles, volumes and areas is seldom considered enticing or fun.Could the opposite be true?Over the last 10 years, weâve seen mathematics creeping into films and television shows; The Big Bang Theory is a prime example of such. Granted, equations are not central to the plot and, quite frankly, only the first few shows were math-heavy. After that, algebraic work popped up only occasionally.Still, it is nice to see complex calculations playing out in a popular arena, and itâs even better that both male and female characters take part in tweaking the equations; a mere 20 years ago, cinematic mathematicians could only be male!Now itâs your turn to master basic geometry equations and you want the most efficient way of doing so.

Image by monicore from PixabayYou might be tempted to think âcircleâ, âtriangleâ or âsquareâ and youâd be absolutely correct.Each of those geometric shapes fall into one of these four general categories:Triangles have three sides; the sides may be of equal length (equilateral triangle) or all different length (scalene triangle).A quadrilateral is any four-sided polygon. Those would be rectangles, squares, rhombuses, diamondsâ¦the parallelogram, a shape that has 2 pairs of equal sides, is also a quadrilateralPolygons: literally âmany sidesâ. These shapes can be triangles, hexagons, pentagons⦠all of those âgonsâ are polygons. Essentially, anything that has straight sides is called a polygon.Circles are a class onto themselves because they have no straight linesTheir unique characteristics include:Squares have four equal sides and four right anglesRectangles have two pairs of equal sidesA trapezoid has on ly one pair of parallel sidesA trapezium has no sides of equal lengthRhomboids: opposite sides and opposing angles are equalThe isosceles triangle has two equal sidesRight triangles have one 90-degree angle opposite of the hypotenuseEach of these shapes has its own formula to calculate its perimeter, area and angles. Some you may be familiar with, such as the Pythagorean theorem while others are perhaps a bit less memorable.Letâs take a look at them now.Do you need help with your geometry studies? Perhaps you could find a geometry tutorâ¦Calculating TrianglesStarting with the shapes of the fewest sides (but sometimes the most complicated formulas), we tackle geometric formulas head-on!The simplest formula for the perimeter of any triangle is a+b+c, with each letter representing a side. It is beautiful in its simplicity and easy to work with, provided you know each side's length.Letâs say your triangle has these measurements: a = 3 inches, b = 4 inches and c = 5 inchesIts perime ter would then be 3+4+5=12 inches.Clearly, this is a triangle is neither equilateral nor isosceles; nor is it a right triangle. How would we calculate the perimeter if only two values, the bottom and one side, are given?In such a case, we have to draw on Pythagorasâ theorem: a2+b2=c2. You remember that one, right?First, draw a line from the triangleâs peak straight down to its base. This line, h, should be perpendicular to the base, thereby forming two 90-degree angles â" one on each side of the line.You now have two right triangles, one of which has a measurement for both a and b. From there, it is a simple matter to plug known values into the theorem (donât forget to square them!) and find your missing value.Letâs try it with a fictitious triangle:a = unknown b = 5 c = 7a2 * 52 = 72a2 * 25 = 49 the unknown value must stand alone on one side of the equationa2 = 49 â" 25 move 25 to the other side of the equal sign, subtracting it from the given value of ca2 = 24Now you hav e to calculate the square root of 24 to find the value of 'a', which is 4.898. Once you've calculated the perimeter of one right triangle, you must calculate the second to get the dimensions of the original triangle.Congratulations! You now know how to calculate the perimeter of any triangle! This and similar triangles signs are used to urge caution on roadways Image by Gerd Altmann from PixabayCalculating Trianglesâ AreaWhile perimeter calculation is a rather simple endeavour, figuring the area of a triangle is a bit more involved.If values are given for all three sides, you may apply Heronâs Formula:area = square root of [s(s-a)(s-b)(s-c)], with 's' being the semi-perimeter, that is (a+b+c)/2It only looks complicated; remember that, when working with a formula, you only need to plug in known values to solve for the unknown. When thought of in that way, the Heroâs Formula, as it is also called, is pretty easy!Now, for âarea of trianglesâ equations where one or more values are unknown.If you know only the value of the triangleâs base and its height, you may apply: area = ( ½) * b * hIf only the length of two sides and the degree of the angle joining them are known, you would use trigonometry to find the missing values. The basic formula is:Area = ( ½) * a * b * sin C Keep in mind that lowercase letters signify line measurements while uppercase letters represent angles.If you only know the values of sides a and c, you would plug them in and calculate sin B. Likewise, if you know b and c, you would employ sin A to get your triangleâs area.Why not practise those for a while before moving on... A=a2 and for rectangles, it is A=l * w. Simple, right?Things start getting complicated when we get into parallelograms and trapezoids; to solve both of those equations, you will need to know the height of the shape (h) an d the length of the base (b) â" the line at the bottom.Once you know those values, choose the appropriate formula for the shape:b * h = area of parallelograms ( ½)(a+b) * h = area of trapezoids, where âaâ represents the side opposite of âbâ.Quadrilaterals may just be the easiest shapes to work with. If you need extra practice, there are plenty of resources online where you can find geometry worksheets and equations to sol ve.Calculating PolygonsWhether you are confronted with an apeirogon (a polygon with an infinite number of sides) or the more familiar hexagon, you need to know how to calculate its perimeter and area.Luckily, apeirogons are only hypothetical; imagine having such a figure to calculate an area for!If your polygonâs sides are all the same length, you can apply P=n * v, where ânâ is the number of sides and âvâ is the value of each side.If said polygonâs side are not all the same length, you will have to add up those values to get its perimeter. The stop sign is perhaps the most renown regular polygon Image by Walter Knerr from PixabayCalculating Areas of PolygonsThere are several ways to realise the value of any polygonâs area, some of which involve calculations for triangles.First, we tackle the equations for a regular polygon; one whose sides are all the same length. Before we can start any ciphering, we have to determine the polygonâs radius.That involves drawing a circle inside the polygon in such a manner that the circleâs perimeter touches the polygonâs perimeter. This is called an inscribed circle. Once we know that radiusâ value, we can apply this formula:A = ½ * p * rFormulae get more complicated the more sides the polygon has.Letâs say the number of sides is represented by ânâ and sides by âsâ. The radius, also called apothem, is designated âaâ. Of course, âAâ represents âareaâ, yielding a formula that looks so:A = ns/4 v 4-s2From here, the formulas get ever more complex. Do they l eave you struggling with the basics of geometry? You can refer to our complete guide!Calculating CirclesCircles involve neither angles nor lines and their perimeters are called âcircumferenceâ. However, their calculations do require at least a line segment which is instrumental to any formula for circles.Oddly enough, it seems that the formula for calculating areas of circles is more renown than perhaps for any other geometric shape: pr2, or pi * r2Surely you know/remember that pi (p) has a value of 3.1415...The less-renown formula concerning circles, the one for calculating circumferences is: 2 * p * rBear in mind that these are formulae for calculating the area and perimeter of two-dimensional shapes; once they gain an additional dimension â" they become 3-D shapes and merit a calculation of volume as well as area and perimeter.Letâs not go off on a tangent, here; weâre quite happy to provide formulas for these basic geometric constructions...But you donât have to stop here; latch on to our beginnerâs guide to geometry!
