Introduction

If you play a transposing instrument such as a Bb Tenor or an Eb Alto saxophone, you may need to transpose your sheet music to be in the right key.

For example, if you have a piece of music for a Flute that is in the Key of C and you play it on an Alto saxophone, you will need to transpose the piece into the key of A.

How to use it:
Locate the original key you are in. For this example, let’s say that you are in the key of C. Let’s also assume that the chords in the song
are C major, F major and G major. Their numbers as listed at the top of the grid are 1, 6, and 8.
Now, decide which key you are moving (transposing) to and calculate the number of semi-tones (steps) you are moving up or down.
For this example, let’s say that you are transposing to the key of D. Maintaining the same numbers as the original key of C (1, 6 and 8),
you will see that your new chords are D major, G major and A major.
Remember to keep the same type of chord that was in the original key. For example, if the original chord in C was a G7 instead of G
major, then your transposed chord in the key of D would be an A7. The same goes for a minor chord. A minor would become B minor.
Note that the notes in parenthesis are the flat versions (enharmonic equivalents) of the original key. An A# is the same as Bb, etc.
