In a piano accompaniment with a solo outline, is there any reason that a transcriber cannot use the parallel movement device when moving from the solo outline to the RH of the piano accompaniment? Also, is it acceptable to use the parallel movement device as the first part of a full-measure in-accord when moving from the solo outline to the RH of the accompaniment?
In conferring with my committee, we agree that the parallel movement device should not be used in these instances. Reserve the use of this device to rare moments when the left hand is in parallel motion to the right hand. The solo outline is for reference – the pianist is focusing on their part – and all the info should be there.
