Rhythm Lab
Read and tap rhythms against a metronome, with timing feedback on every single tap.
What it trains
Rhythm Lab shows a rhythm, counts you in, and listens to your taps on the screen or the space bar. Each tap is marked early, late or on time, in milliseconds. A short calibration step measures your device’s audio and touch delay, so the feedback is accurate on a laptop, tablet or phone.
- Reading rhythms with whole, half, quarter, eighth and sixteenth notes, dots, rests and triplets
- Simple, compound and irregular time signatures: 2/4, 3/4, 4/4, 5/4, 5/8, 6/8 and 7/8
- Keeping a steady pulse, including through bars where the metronome goes quiet
- Recognising written rhythms by ear
Exercises
- Read and tap
- A rhythm appears. After a count-in, tap it along with the metronome.
- Steady pulse
- Tap every beat. Some bars drop the metronome so you keep time on your own.
- Rhythm by ear
- Hear a rhythm and pick the matching notation from three options.

Reference view
A rhythm reference lists every note and rest value with its counting, and plays any example at your tempo.
