Free online chord player
The Ajenza Chord Player lets you hear any chord instantly in your browser — no app, no sign-up. Pick one of the twelve roots and a chord quality (major, minor, diminished, augmented, sus, 6ths, 7ths, add9 and 9), and it shows the note names and plays the chord, block or arpeggiated, synthesized live with the Web Audio API. Choose a key and tap a common progression — I–V–vi–IV, ii–V–I, a 50s progression or a 12-bar blues — to hear the diatonic chords play in sequence. Great for songwriters, and for guitar or piano learners.
