Simulacrum involves a single rubato melody line performed by a soloist while accompanied by various melodic cells from the
remaining ensemble members. When the soloist is finished the lead line another player can begin it, and then another if desired.
Players can switch roles (become the soloist or accompanist) whenever desired as long as it is agreed upon beforehand.
I recommend two or three iterations of the lead line. Duration is therefore variable.
Everyone reads off of the score which is available in all keys and clefs.
