Music Theory Apps


These free apps for musicians are aimed at teachers and students of music academies, but if you're an hobby musician, you're welcome to try them. All apps have been tested with Android 4.1.1 and up on budget smartphones and small tablets.

No Android? Not to worry, with Blue Stacks you can use these apps even on your Windows PC (Mac is coming up): Blue Stacks

1. Assistant Harmony Analysis is a tool that helps you analyse a chord in its tonal context. AHA tells you what the prevailing key is, the chord degree and the chord type. It is based on classical harmony (with the Roman numerals). The database is big: 12 x 8 keys in major, 12 x 8 keys in minor, 312 chord types and 13,884 chords.

Read more about this non-profit and ad-free tool in the manual (pdf).

2. There are thousands of chords, but all of these chords are nothing more than a few chord types that have been transposed to several keys. If you learn to recognize the most important types, you will recognize the majority of the chords in any composition.

This app comes with a free tutorial on chord types!

3. This app was made for musicians who want to train relative pitch within a key. You can also test if you recognize sequences of tones with subtle differences. It's more difficult than you might expect.

4. The next app was made for musicians too, but it can be enjoyed by non-musicians as well. Most people will recognize the sound of an instrument. But will you recognize 3 different instruments that play simultaneously? Or even 5 instruments?
