" She said she learned it in three weeks—but somebody else told me she really did it in two.” These feats are routine at Meadowmount, in part because the teachers take the idea of chunking to its extreme. Students scissor each measure of their sheet music into horizontal strips, which are stuffed into envelopes and pulled out in random order. They go on to break those strips into smaller fragments by altering rhythms. For instance, they will play a difficult passage in dotted rhythm (the horses' hooves sound—da-dum, da-dum). This technique forces the player to quickly link two of the notes in a series, then grants them a beat of rest before the next two-note link. The goal is always the same: to break a skill into its component pieces (circuits), memorize those pieces individually, then link them together in progressively larger groupings (new, interconnected circuits).
