To explore how expert musicians memorize performances we have used longitudinal case studies of concert soloists preparing for performance. We examine behavior during practice to understand into the learning process. Musicians constantly start, stop, back up, and repeat, making split-second decisions as they continuously evaluate every aspect of technique, interpretation, and performance. We have used this wealth of behavioral data to test the application of psychological theories of expert memory, problem solving, and motor control to the domain of music. If you would like to study your own performance using our methods, please read projects: Performance Cue Survey and Study Your Own Music Performance.
