It must be pointed out that the pitch p of these notes is
memorized so that the stem of the further spacing note will join them into
a chord. This stem top and bottom pitch is reset at each spacing
note.
REMARK : Notes of duration longer than whole notes are
always non-spacing. This saves one useless definition, since these notes are
always longer than other simultaneous ones. If needed they can be followed by
normalshapemediumseriesnormalshapemediumseries\sk to force spacing.
