ABSTRACT
Musical training had an influence on the pitch interval identification performance: trained listeners improved their performance as stimulus duration increased, whereas the untrained listeners did not. Moreover, untrained listeners almost always incorrectly classified unison pitch interval trials as “octave intervals” when there was a change in instrument. Hence, the untrained listeners confused the octave interval with an instrument change. This replicates the result reported by Hesse (1982) and Experiment I in this paper.
