Which time signature fits?

Worked example: five crotchets

Add up one bar, then find the signature that holds exactly that much.

1. In crotchets: 1 and a half, a half, then three crotchets: 5.
2. No dotted groups: the beat is a crotchet.
3. Five crotchet beats: .

The grouping decides

Two time signatures can hold the same amount:  and  both hold six quavers. The beams decide: pairs show crotchet beats, threes show dotted beats.

Remember

• Add up one bar, in crotchets.
• Same total? The grouping decides.
