Store listing
By Martin Moroni, from the App StoreDescription by Martin Moroni Written by the developer, not by AppBrain. Click to read.
KingMetronome is a rhythm training lab for drummers and serious musicians: polyrhythms, sight-reading, metric modulation, claves, displacement and more specialized modules. One-time payment, no subscriptions, no ads.
15 SPECIALIZED MODULES:
Metronome, Rhythm Reader, Claves, Negative Space, Timing Test, Adaptation, Amalgams, Displacement, Polyrhythms, Metric Modulation, Tap Trainer.
- Elastic Phrase — Phrases with gradually changing tempo
- Polymeter — Two time signatures playing simultaneously
- Microrhythm Masterclass by Malcolm Braff — Infinite phrasing slider between straight pulse and grooved feel
WHAT MAKES IT DIFFERENT:
◆ MICRORHYTHM MASTERCLASS — Built around Malcolm Braff's General Theory of Rhythm. The infinite zone between straight and grooved that no other app has.
◆ TIMING TEST — Find out how precise you are, down to the millisecond.
◆ NEGATIVE SPACE — The metronome disappears for 1, 2 or 4 bars. Can you hold the tempo alone?
◆ POLYRHYTHM TRAINER — 3:2, 4:3, 5:4, 7:5. Hear them, feel them, master them.
◆ AMALGAMS — Additive rhythms (4+3, 3+3+2). Hypnotic and addictive.
◆ METRIC MODULATION BUILDER — Build any tempo equivalence you can imagine.
◆ TAP TRAINER — Tap along to find your average tempo and consistency.
