iKey Transpose is the 2nd app in our iKey series. iKey Transpose is a simple, no-frills musical key transposition reference tool. This app will simply allow the user to visually transpose between all of the possible major and minor keys and view each note and chord of both keys and how they relate to each other. New in version 2.0 iKey Transpose will also allow for transposing instruments such as trumpets or saxophones.

Imagine your asked to switch from the key of A to the key of D flat. Now maybe you know all of the notes of D flat are flat except for F and C. You may even know some of the chords of that key. Say you have music written in A. Now you can see that any time you see B minor you will know that you will transpose it to a E flat minor.

iKey Transpose will appeal to professional, student and hobbyist musicians. iKey Transpose is exceptionally easy to use and is handy as a quick reference for the pro or the key to understanding how keys relate for the student or hobbyist. iKey Transpose and it's companion app iKeySig can give you insight into how music works and how the tones and chords interact with each other.

Ratings and Reviews

The updated version is not good


I used to love this app. The updated version is confusion and does not offer minor keys.

Nice app


Quickly shows chords when wanting to change keys. I use it for keys changes for worship songs. Worth the .99 cents price

Easy to use


Songs are rarely written in my key so this exactly what I've been looking for. Now I can sing when I play my uke. Love, love, love it!
