.Howie,yes I SHOULD be able to transcribe it.But for no reason that stands up to scrutiny,I've always played the melodeon by ear and tried to play intuitivly.If I need to work things out or sight -read ,I do it on the english concertina.The trouble arises when I can play a tune or song on one instrument but not another.
          As probably for most people,time is the issue.
