A vocalist rapidly sings a complex melody. Why does perceived rhythmic regularity degrade when the note durations become extremely short?

💡 Explanation

The perceived rhythm degrades because temporal acuity limits the ability to distinguish very short note durations. The auditory system has a minimum temporal resolution threshold; therefore, durations below this threshold are perceived as equal, rather than accurately timed. Auditory stream segregation is related to pitch rather than rhythmic precision.
