Welcome to the RandomChord.com Chord Generator
A useful resource for all musicians — improvisers can make sure they can play over any harmony; songwriters can find that elusive lost chord to complete their chord progression.
Each chord comes with its own looped backing track and an explanation of the scale choices that fit with it.
Choose a chord from the drop down menus and click 'Go', or click 'Random' to have a random chord generated for you.
