Practise time signatures so you can play your favourite tunes!
Time signatures tell us about beats.
In grade one you have already been introduced to some of the time signatures (2, 3 and 4 crotchets in a bar) and in grade two you will be expected to know a few different ones which have varied grouping patterns. Remember that the top number is the number of beats in a bar and the bottom number is the type of beat.
