Chord Exclamation Mark!

Adding the "!" to the app name is no exaggeration. This is the chord app to beat all chord apps. A huge amount of thought has gone into this and it is by far the best app to help illustrate chord and scale structures to beginners, and it is a handy encyclopedia for seasoned pros. Someone said it is great for teachers and they were absolutely right. Its also good for gigging musicians, students, and beginners just looking to find the right chord, scale or harmony for a musical idea.
