The present paper investigates the influence of the bichord interval between two pure-tones on perceptual simultaneity. In the experiment, 30 participants (musicians and non musicians) listened to tone pairs (bichords: C-D; C-E flat; C-F sharp; C-G) with different degrees of asynchronization and indicated whether two tones had been simultaneous or successive. The method of constant stimuli was used. An ANOVA showed that bichords intervals were perceived with different degrees of simultaneity (p< 0.0001). Tones that are less distant in frequency are not necessarily easier to perceive as simultaneous. This result suggests that judgement of simultaneity cannot be accounted for only in terms of frequency or temporal relationship between single stimuli at the physical level. The effect of a non temporal variable concerning the perceptual moment hypothesis is discussed.

Abstract
The present paper investigates the influence of the bichord interval between two pure-tones on perceptual simultaneity. In the experiment, 30 participants (musicians and non musicians) listened to tone pairs (bichords: C-D; C-E flat; C-F sharp; C-G) with different degrees of asynchronization and indicated whether two tones had been simultaneous or successive. The method of constant stimuli was used. An ANOVA showed that bichords intervals were perceived with different degrees of simultaneity (p< 0.0001). Tones that are less distant in frequency are not necessarily easier to perceive as simultaneous. This result suggests that judgement of simultaneity cannot be accounted for only in terms of frequency or temporal relationship between single stimuli at the physical level. The effect of a non temporal variable concerning the perceptual moment hypothesis is discussed.
