Music Rehearsal Increases the Perceptual Span for Notation

Skilled musicians read scores more efficiently, but does rehearsal itself widen how much of a score a musician can take in at a glance? This study measured the "perceptual span" for musical notation across repeated rehearsals.

Highlights

  • Skilled musicians initially showed a slightly larger span for challenging passages (5 notes vs. 4).
  • Spans grew incrementally in both groups, and skill differences disappeared by 20 rehearsals (a span of 11 notes).
  • Improvements in perceptual span correlated with performance speed, suggesting perceptual learning drives early gains in rehearsal.
