Listen to how chords sound on the piano.
Use the player above to hear the notes together and notice the character of the chord. Try repeating the sound a few times and see if you can hum or play along. Listening actively is a great way to train your ear and to recognize chords in songs.
Descriptions of how different chords sounds:
Major – bright and somewhat happy.
Minor – sad and melancholic.
Diminished – tense, unstable (due to the lowered 5th).
Augmented – bright but unsettled (due to the raised 5th).
7 – tense and somewhat bluesy.
m7 – a bit sad and melancholic, but more ambivalent than the minor triad.
maj7 – bright with some nostalgia, and somewhat jazzy.
m7♭5 – dark and unstable, feels incomplete and often leads to a resolution.
6 – brighter than a major 7th but softer than a plain major triad, and subtly jazzy.
m6 – combines the darkness of a minor chord with a gentle lift from the added 6th, slightly tense.
