The Central Strategy of Music Practice: A Blow-by-Blow Account
Micah F. Killion 1, and Robert A. Duke 2
Individual practice is a ubiquitous component in the development of expert music performance, and music pedagogues for centuries have offered prescriptions to aspiring musicians regarding effective music practice. These prescriptions are often characterized as practice strategies, yet they often fail to precisely convey the moment-to-moment process of skill learning, one that embodies iterative sequences of prediction (intention), performance, perception, and adaptation. There is as yet no systematic research that documents the behavior of artist-level performers engaged in successful individual practice. This study is a detailed analysis of individual practice of six artist-level trumpet players. Recordings were analyzed in detail to document how the artists allocated time, responded to discrepancies between intentions and outcomes, and organized practice activities to effect moment-to-moment changes in their playing. The results reveal that expert practice can be analyzed and described in terms of one central strategy: formulating vivid goals, performing, perceiving discrepancies between intentions and outcomes, and adapting subsequent performance trials to render momentary challenges surmountable. This is followed by iterations in which expert musicians adjust the parameters of each succeeding performance trial in ways that reduce the discrepancy between intentions and outcomes while maintaining a high percentage of successful performance trials.
