Common motion (when 2 things do same thing simultaneously, moving up and down together) Synchrony (going on and off at the same time. Auditory stream segregation: the proximity principle (both frequency proximity and temporal proximity are strong perceptual grouping cues.

If stream is fast (temporal proximity fast) high-low-high-low sounds can be heard as two different groups: high notes and low notes. Auditory stream segregation: the proximity principle (both frequency proximity and temporal proximity are strong perceptual grouping cues)
