I’m interested in notating transitions between different bow pressures. The two options that I’ve seen in literature are:
black wedges that thicken as increasing bow pressure is desired (as found in Saariaho scores)
boxes that are empty (ordinary pressure), half-filled in black (for half pressure), and completely filled in black (full bow pressure, distorted sound), with dotted arrows showing transitions between them
Does anyone know how to approximate these in Dorico?
