My Piano Assistant is a reference book of chords (with all inversions), scales and intervals. Given the name of an item and a root, the app shows the item formula, symbol (for chords and intervals), the sequence of notes and their positions on the piano keyboard. It also allows to listen to a selected item.

Features:
* ~40 chords with all inversions
* ~170 scales
* ~30 intervals
* user-defined chords, scales and intervals
* item playback
* quick search
* bookmarks
* clean and simple user interface

NOTE: My Piano Assistant is not a “virtual piano” application and it does not allow to play on the virtual keyboard. If you are looking for such kind of application this one won’t be of use to you.

If you have any questions, bug reports or ideas, feel free to contact me via email or the app community on the Google+ (http://goo.gl/APMqQE).

In case you are interested in getting access to early test versions of the app, please, follow instructions here: http://goo.gl/BC5CqH
