A chord is a set of notes that are sounded simultaneously. In Western music, the most frequently encountered chords are called triads, as they feature three notes – the root note, and the intervals of a third and a fifth above the root. Of course chords can get much more complicated than this, and in jazz or contemporary classical music is very common to encounter chords with more than three notes.
Chords are the colours that give music its flavour. When your ears can recognize a major triad, a minor 7, or even a crunchy altered chord on the spot, you can strum along without charts, build richer arrangements, and follow any jam with confidence.
Press Play, hear a chord, name what you heard. Start with the four basic triads, major, minor, diminished, augmented - then unlock sevenths and extended voicings as your accuracy climbs. Within a few sessions you’ll feel each quality before you even think about note names.
The screen shows a chord symbol; you build it and play it on the virtual keyboard or your MIDI controller.
Two or more notes appear on a staff; identify the chord. Linking notation to sound keeps sight-reading from feeling like code and lets you “hear” sheet music in your head before you play.

A minute of tweaking keeps every session in the “stretch but don’t stress” zone.
Once you have finished a round of drills, open the Chord Player tool. Type or click any chord symbol and the player will:
Spend a minute breaking down the chords you just trained, then head back to the exercises. That back-and-forth between ear training and active listening locks every new quality into long-term memory.
Five focused minutes in the drills is the perfect stretch before you chase high scores:
Each game starts gently, then ramps up difficulty as your score rises—a clear marker of progress day by day.
