Metrum: a circle for groove
A browser-based rhythm trainer lets musicians place notes on a circular bar, adjust their timing, and practise different time-feels.
- For
- Drummers and musicians practising time-feel
- Worth noticing
- Patterns stay in the browser on the user's device; the page says Metrum does not receive them.
Field notes
The circle represents a bar, with selectable beat counts and subdivisions; notes can be repositioned by dragging. The page describes pattern rotations, stickings, grouping marks, notation, and sequence mode, and says saved patterns remain in the local browser rather than being received by the project. A seven-day full-feature trial requires email or Google sign-in; the page lists a one-time $10 purchase and says native mobile apps are planned, while current access is browser-based.
