Simple and intuitive. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- User Reviews I'm a piano teacher of 15 years and have more and more students who want to play chords and improvise. This app is a perfect resource for them. I like it because it's thorough but, at the same time, straightforward. I am new to piano and familiar with some scales and chord progressions, but this app will help me to understand and explore various combinations. I pair this app with additional learning material online to help me fully understand the math/science behind music. This app is excellent for understanding scales, chords, chord progressions, and the circle of fifths. I like the easy-to-use interface. It only includes standard scales and chords. I have another app with many complicated and confusing scales that I've never heard of, much less can pronounce. I just wanted something to show me the standard scales and chords, which this app does. It also sounds like a chord or scale. It gives you so much when you’re stuck composing. I’m relatively new to music theory, and this makes everything I’ve been learning about chords super clear. I have taught piano for 33 years. This is the best app for any level of the student. It is so easy to use; kids love it when I use the iPad in their lessons.
