![]() ![]() He even composed short pieces with subdivided elements to see if musicians rushed those subdivisions (they did), and if listeners judged subdivided beats as “slower” than surrounding clean beats of the same tempo (again they did). In section two (pp122-130) Bruno Repp turned a stopwatch to his, and Yale University’s, extensive record collection to see if famous pianists ‘rush’ the (subdivided) first variation after an (un-subdivided) theme in Beethoven piano sonatas, finding that they nearly always did. And when listening to a clean pulse followed by a subdivided pulse participants invariably judged the subdivided pulse as sounding slower than the clean one of the same tempo. quavers) at the same tempo of a clean pulse (in crotchets) just preceding it, participants invariably tap too fast. ![]() The researchers discovered that when asked to tap a subdivided pulse (e.g. Section one (pp114-122) details experiments that involved listening to a metronome before tapping out its pulse. Scientists have long recognised that a “filled” time interval is perceived as longer than an “empty” one of identical duration, a phenomenon known as the filled duration illusion (FDI).Ī classic way of filling a time interval, or a beat, is by metrical subdivision for instance if a metronome is beating out a pulse of crotchets (quarter-notes) then subdividing it into quavers (8th-notes) ‘fills’ each beat with an extra note and subdividing it into semiquavers (16th-notes) ‘fills’ each beat with an extra three notes.īruno Repp and Meijin Bruttomesso set out to investigate if a subdivided beat did indeed seem to last longer than a ‘clean’ beat and if so, whether performing musicians (and non-musicians) rushed the subdivisions in order to ‘correct’ the tempo. ![]() A filled duration illusion in music: Effects of metrical subdivision on the perception and production of beat tempo.Īdvances in cognitive psychology vol. ![]()
