Tempo
Metronomo plays from 20 to 480 BPM, in whole beats per minute. A new Groove defaults to 120 BPM.
A window on the scale
The tempo slider shows a 20–100 BPM window of the full 460 BPM range. The current bounds of the window are annotated below the slider’s navigation arrows.
The width of the window is set via Settings → Preferences → BPM slider resolution. The choice is 20, 30, 40, 50, 60, 80, or 100 BPM, with a default of 40.
To quickly set a desired tempo:
- Drag or tap the slider to set any tempo inside the current window.
- Tap the left or right margin of the slider to shift the window’s bounds 10 BPM in the indicated direction. The selected tempo will not change.
- Drag to either end of the slider and hold to repeatedly shift the window’s bounds 10 BPM until you end the action.
The current tempo selection will move as the window’s bounds change and eventually re-center when it falls outside the new bounds.
When the tempo takes effect
A new tempo takes effect when you end your drag or tap. Settings → Preferences → Apply changes decides whether playback restarts the bar at the new tempo or finishes the current bar first. See Changing a Groove while it plays.
Tempo markings
The conventional Italian tempo marking is presented above the slider adjacent to the BPM number. These labels align to the following ranges:

| Grave | 25–39 |
| Largo | 40–59 |
| Larghetto | 60–65 |
| Adagio | 66–75 |
| Andante | 76–107 |
| Moderato | 108–119 |
| Allegro | 120–155 |
| Vivace | 156–167 |
| Presto | 168–199 |
| Prestissimo | 200–480 |
This presentation-only label on the tempo slider also appears on the lock screen while the metronome is playing — see Playback.
