The number of beats in each measure typically depends on the time signature of the music piece. The most common time signatures include:
- 4/4 (four beats per measure)
- 6/8 (six beats per measure, counted in groups of two)
- 3/4 (three beats per measure)
- 2/4 (two beats per measure)
From your options, if we are considering the standard options, the correct answer would generally be:
- four beats per measure (if referring to 4/4 time signature).
