to put it simply
All the whole notes & Half notes take place on the last key of each line

Whole notes = hold for 4 beats
Half notes = hold for 2 beats

beats do not = a note
but they measure the length.

All the lines have keys ending in whole/half notes so it's helpful to use that as a way to transition to the next line.
dont stress about getting the timing perfect
