mark ,that is very helpful,Ihave no trouble NO 4.
lets see if Ihave this right,
1.when Gorge picks a crotchet and a quaver,he picks down up with a quaver rest in between,so in effect he plays his quaver rest with adown stroke silently.
next for 1. you are suggesting playing three quavers DDU quaver rest,so you would count 1234,but play 123.
if Ihave this right Ihave to say youhave explained it really well,thanks again.
