A community orchestra used to mark rehearsal attendance as proof that every musician was ready for a concert. The conductor later noticed that some players attended every session but still missed entrances when the music began at an unfamiliar point. The orchestra therefore added three checks. Each player first marked the two passages that required help. After guided practice, the player explained the cue for each entrance without looking at the conductor's notes. At the next rehearsal, the ensemble began from a different measure to see whether the cue could be recognized in a new context. Attendance continued to be recorded, but it was no longer treated as evidence of all three skills. A player who missed a rehearsal completed the missed practice before taking the checks; the checks did not erase unfinished work. The new records separated presence, explanation, and transfer. This helped the conductor decide whether a player needed more practice time, a clearer cue, or another attempt from an unfamiliar starting point.
