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.

Instruments and clefs

Rhythm notation on a single-line staff. Tap on the screen pad, click, or use the space bar. Sounds: metronome click and a soft tap tone.

Reference view

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

Who it’s for

  • Players of any instrument who want to read rhythms accurately
  • Anyone whose timing drifts when the metronome is not there
  • Students meeting 6/8, 5/4 and 7/8 for the first time

Who it isn’t for

  • Drummers looking for kit grooves or rudiments
  • Anyone wanting a standalone metronome app — the metronome here serves the exercises
