Chord Master is a web application for musicians to find new chord and create the chord progression.

Chords in the progression are represented by the lead sheet symbol. To build a chord, you can click the + button to add a chord, select the chord type and inversion in the dropdown menu, and choose the root note by clicking its key on the keyboard interface. You can also edit, delete or copy a chord. You can click the play button to listen to the entire chord progression. After finishing the progression, you can download the track as a MIDI file, and use the progression for your song.
