Music Theory Companion Customer Insights

1. Update: The developer sent an explanation of my "bug" comment, so I will upgrade my rating to 5 starsIt's an awesome app!!! Lots of great music theory with a moving circle of fifths And keyboard that helps you make sure what you're hearing is what's matching up with your ears! Very awesome for ear training or site reading!!! And many more applications!!! It's very user friendly!!! Great appWould have rated it more but I literally don't have a clue on it's usage.

2. As I explore the app and tap on random buttons to see what it does, my husband started giving me funny looks because I kept saying, aloud, "Oh wow!" "Oh my gosh this is so cool." "It can do that too?" And the Matching Chords tool? 😍👌🏻 I'm a novice multi-instrumentalist with enough music theory knowledge to do the basic stuff.

3. You have an option to view the scales, chords, and notes on a piano keyboard and also a guitar fretboard.Brilliant app if youre starting to learn theory or want to brush up.

4. Its the perfect tool to compose and have fun with; all scales, chords, and notes can be played back to you easily along with a very logical interface that facilitates learning.

5. The ability to listen to chord progression quickly and accurately with out (as a new learner) spending 20 minutes at the piano to address the chords and then learning a possible mistake is a massive time saver.

6. 3 stars mainly because handling chords is quite annoying.This is amazing! The app has opened up a whole new world of music theory.

7. It's going to be so useful in so many ways.For the purpose of a quick, practical reference that helps to bridge the gap between abstract concepts and the effort to make thoughtful, musical expression, this app exceeds my expectation.

8. Could you guys possibley add an option for 'chord creation' where you could insert notes and have the app tell you all the ways it could be named, and maybe the option to invert a chord once selected.

9. I dont want to have to rely on charts, learning by ear and making the connections in my own head are easier as it listens to the notes you play and recognises them, trusting your instrument is in tune.

10. It has proved itsel a useful composition tool.Interesting app with many features, but there appears to be a bug in the "scales practice" section.

11. The little red arrow bounces around at random with the circle on circle of fifths, and selected notes will play only randomly when selected.
