-4/4 time means 4 beats per measure.
*so there are 1 2 3 4 beats per measure*
-half notes are 2 beats long
*so beats 1 &2 can count as one whole half note, beats 3 & 4 can count as another half note*
- So if we are doing half notes only then there are 2 whole half notes per measurement.
in total we would have 8 half notes in 4 measures
