Practising at 140 BPM
If 140 BPM feels too fast for a passage, drop to a tempo where you can play it cleanly three times in a row, then come back up 2–4 BPM at a time. If it feels easy, try putting the click on beats 2 and 4 only (set the metronome to 70 BPM), which trains you to feel the pulse yourself.
Need a different speed? Use the slider, or open a preset: 40 · 50 · 60 · 70 · 80 · 90 · 100 · 110 · 120 · 130 · 150 · 160 · 170 · 180 · 200 BPM.
