Learn (all) Piano Chords

Hello! My name is Mike, and I am a composer. Just. Like. You! =)

This is my complete list of all main chords that I personally use as a composer.

You can now learn and apply all these chords in your music, by using the formula of semi notes (half steps). Every chord formula below can be used on any root key.

R = Root key of the chord. The numbers that follow after “R” are the number of keys you need to step to the right to get to the next note in the chord.

PS. Make sure you bookmark this page, you are going to go back to it a lot! =)
