| Abstract | The timing of pedal depressions and releases was measured relative to key depressions and releases in two pianists’ performance of Robert Schumann’s Träumerei on an electronic instrument. Each pianist provided nine complete performances, three at each of three tempi, which were analyzed by examining in detail those positions in the music in which the pedal was used consistently. The principal questions were whether and how pedal timing adjusts to changes in global tempo (across performances) and in local tempo (within performances): Do pedal-release times, onset times, or change (onset minus release) times exhibit absolute or relative invariance across either or both of these tempo changes? The results do not suggest any simple answer, since neither type of invariance was observed consistently. Pedal timing emerges as having a complex pattern that is sensitized to local and global tempo changes in varying degrees, yet exhibits consistency across repeated performances by the same pianist. There were striking differences in pedal timing between the two pianists, who differed in level and skill. |
