How to practise with a metronome
Start slower than you think you need: at a tempo where you can play the passage perfectly three times in a row. Accuracy learned slowly carries over when you speed up; mistakes practised fast become habits. Raise the tempo by 4 to 8 BPM at a time, and drop back when it stops being clean. The speed trainer above automates this.
Make the click do less
Once a passage is steady, silence some beats. Clicking only on beat 1, or only on 2 and 4 like a jazz drummer's hi-hat, forces you to keep the pulse yourself. Click a beat circle until it turns dashed to mute it.
Use subdivisions for fast notes
If sixteenth notes rush or drag, turn on the sixteenth subdivision at a slow tempo so every note lines up with a click, then switch back to plain beats.
Compound meters
In 6/8, 9/8 and 12/8 the beat is a dotted quarter, so the metronome clicks two, three or four times per bar, with softer eighths in between if you choose triplet subdivision. 7/8 is counted in eighth notes with an accent at the start of each bar.
Did you play it in time?
Claptoscore listens to you instead of the other way round: tap or clap a rhythm along with its click and it writes out what you played, with a timing chart showing how many milliseconds early or late each note was.
