Quick and Easy Key/Scale App

Great app to quickly and easily listen to a lot of different keys, and scales to pick one for your song. This app has helped me branch out the scales I use to write songs. I wish I could save my favorite scales though.

Wicked Good!

This app is a splendid refresher course of my Music Theory classes almost 45 years ago. Quite useful in many ways!

Very helpful and well structured

For musicians building their ears this app is really helpful. I like the simplicity of the structure and different options for playback. It takes years to build your ears and tools like this are very helpful in providing options.
