Chord Builder is a simple guide that helps you understand how to build chords and teaches you how to build chords without having to know all the chords by heart. Chord Builder contains clearly marked intervals for the C scale, both on the keys and on the guitar fingerboard.  And once you understand and learn everything for the C scale, then you can easily create chords for all other scales just by creating a chord in C and then just moving (transposing) it to the desired position.
