How to Transpose Music on Piano

Posted by Yoke Wong on 8/18/2014 to Learn To Play Piano

As a pianist, knowing how to change the pitch of a song is important. We do this so that the people can sing the higher or lower notes in the normal voice range. This technique is called transposition. Transposition is changing the key of a music piece from one key to another. Once the key is transposed, it will sound either higher or lower than its original key. Transposition is often used by piano accompanists, arrangers, composers and performers. For some musical instruments, transposition is easy. A guitar can use a capo to change keys. An electronic keyboard has button features to change tones. But in an acoustic piano, transposition is done manually.

There are several methods to transpose music.

1. Transposing By Interval

Interval is the distance between two notes. If you are transposing from the Key of C to the Key of D, the interval between these keys is two intervals or a whole step. You will then need to shift all your notes two intervals higher or a whole step higher.

2. Transposing By Scale

This method requires that you master all scales and the corresponding numbers of each note on a scale.

3. Transposing By Chord

While the first two methods are used by most sight readers, this third method is used by most pianists who play by chords. Following is the Chord Transposition Chart.

Chord Transposition Chart

Each column represents a key and its chords. For example, the first column contains the chords for the key of C. First locate the columns for your song's original key and desired key. For each chord in your song, find the chord in the column corresponding with the original key, and note what column it is in. Then find the chord in that same row in the column corresponding with the new key. Replace the original chord with that chord.

The hymn My Tribute is loved by many Christians to sing at church worship services. However, many find the song too high in pitch, and they would request to lower the pitch of the song. My Tribute is originally played in the key of Bb.

Let us transpose the hymn from the Key of Bb to the Key of A to lower the pitch of the song.

  1. Locate the Keys of Bb and A on the top row.
  2. Substitute the original chords of the hymn with the chords of the Key of A. For example, when you come across F maj chord, the new chord after transposition will be E maj chord.
  3. For minor, major and seventh chords, just change the chord name and retain the minor, major and seventh (Bb7 > A7, Ebm > Dm)

Do this process in all songs you would like to transpose. Locate the original key in the chart, find the next key you would like the song to be transposed, and change all chords from the original key to the next key.

Yoke: I recommend that keyboarders/pianists first learn chord theory. That is, they need to know not just the scaled but the chords and the notes that make up the various chords. You do that not with letters but numbers. For example, a Major chord in the root is the 1st, 3rd and 5th note of the major scale of a key. The Minor chord is the 1st, flatted 3rd, and 5th. The maj7 (major 7th) is the 1st, 3rd, 5th, and 7th. The 7th is the 1st, 3rd, 5th, and flatted 7th. There's many sources on the internet to learn this so you can know it cold. Once you have that down you know the root chords and you can play inversions (for example 3rd, 5th and 1st is the 1st inversion). As long as you know that, and you know your scales, you should then apply yourself to learn the Nashville numbering system. This is how you can transpose quickly without need to write out a new chord progression. Now at this point I have been the one to create the chord charts for our church worship band, and my first step when I do it is to number the chords. (Whether I am working from a piano-vocal arrangement or figuring it out from scratch, without any references.) Then I can quickly transpose into another key until we figure out what's the best for the lead vocalist. Unfortunately not all of the musicians playing instruments in the band have the musical knowledge to play from a numbered lead sheet, but having the numbers helps me quickly AND most importantly, ACCURATELY, create a lead sheet for the instruments -- and actually, to create different tonal qualities for the 2 guitarists, I will create one for straight un-capoed guitar, and another for a capo up a few frets. It puts the instrument sound in two different areas giving a more full sound to the band. So, I recommend learning your chords, your scales, and the Nashville numbering system to greatly enhance your versatility behind the keys!

Oh, and also, if you have an iphone, there's an app called "Tempo Slow" (I am not sure if it is available for Android, Windows or Amazon phones.) What this does is if you have the digital audio file on your phone, you select it and you can slow down the music to learn it, WITHOUT it changing the pitch. It has been an app that has been very helpful in figuring out the chord progressions and bass lines for various songs, as well as to learn songs that have many quick chord/bass line changes. By practicing with this app, I was able to master Francesca Battiselli's "Have Yourself a Merry Little Christmas," which is a keyboard led, very fast song, with many chord changes, by repeating it on about 80% of the normal speed, until the changes had been committed to 'muscle memory.'

Yoke, Your instructions are very helpful. Thank you. We usually use lead sheet with chords. What is the numbered sheet so easily used by guitarists? Can you please show us a short example? Do you use a transposing software to get the right key for the vocalists? Helen

Yoke, thank you for being faithful in sending me these invaluable teachings over the years, including Heather's tips above. I am nearing retirement, at which point I will be ready to embark on your in depth courses! I will make time to practise, time I just did not have until soon.

Dear Yoke, re: Your Transposition Chart There seems to be a slight "typo" in the 5th column, which should be headed "E" instead of "D" Thank you.

Thank you Heather and others who left comments here. Blog is a great way to collaborate and share ideas. Love the engagement here. Indeed, scale and chords are the foundation and backbone of transposition.

It has been most interesting to get your piano letters! I now have a situation in my life that I have no possibility to play, but I am grateful for what you already have given me, I wish you all the best!
