The purpose of this study was to examine whether experiences of musical instruments influence on discrimination of two-pure-tone simultaneous intervals. Fifteen experienced and 14 inexperienced subjects were asked to compare a standard stimulus with a comparison stimulus whose lower tone was varied from -4 Hz to +4 Hz, and to judge whether they were same or different. One single tone and four two-pure-tone simultaneous intervals, major second, major third, perfect fifth, and major seventh were used as stimuli. The results showed that the experienced subjects were generally more accurate and quicker in the task than the inexperienced subjects. It was suggested that a schema for discrimination of two-pure-tone simultaneous intervals was formed by exercises on musical instruments, and that the inexperienced subjects also had the schema to some extent.
