About Piano Chords, Scales, Progression Companion PRO
Piano Companion is a flexible piano chords and scales dictionary with user libraries and reverse mode with a flexible chord progression builder. If you can’t remember the name of a chord or scale, this app helps you to find it by keys. For example, just press C, G and you will get C Major as the first chord in the search result. If you don’t see a chord, you can create a custom chord and use it for chord charts or your user library.
The Piano Companion app shows chord and scale notes, degrees, fingering for both hands in major and minor scales – and you can contribute your own custom fingering too. Additionally, you can listen how a scale or chord sounds in the loop or arpeggiated. You can see the list of compatible chords in the selected scale or list of compatible scales for a selected chord.
The app helps you to experiment with different chord progressions using our Chord Progression Builder using relative or common chords.

It has been an invaluable learning tool. I use it for writing and music comprehension. This app covers everything you want to know about music and music theory.
Me like piano app. Me pay moneez nao.
I have had this app since 30th December 2018, and there has been so much hard work put into it that I am still finding my way around it. I have reviewed the app before, but I've gone on and on using it and I still can't do it justice. Thank you, app developer 😄
This app is more than worth the buy.
Excellent app. Gives you more than what you pay for.
