In "copy" for the printer grace-notes are best written in red ink. (2) In piano music when a single part, or row of notes, is to be divided between the hands, one playing one group and the other the next, the stems of the right-hand notes are turned up, and those of the left down (see Fig. 15, latter half of measure). (3) Similarly in some organ music, especially that printed in Germany, pedal notes which are to be played by the right foot have the stems turned up, those by the left, down. (4) In vocal music, when a subsequent verse, though having the same notes, requires different time-values from the first verse, or a translation requires different time-values from the original language, the time-values required by one verse or language have the stems of the notes turned up, those required by the other down (see e, Fig. 18, from Molique's oratorio "Abraham").
