How it works

A major chord uses the root, a note 4 semitones above it, and a note 7 semitones above it. A minor chord uses 3 and 7 instead. The root is fixed; choose the other two notes. Sound is optional.

Notes use C D E F G A B. ♯ raises a note one semitone; ♭ lowers it one.

Use a comfortable volume. Sound plays only when you press Play.
