The perception and production of complex musical sequences was tested, while varying either the number of major diatonic pitches or inter-onset intervals (IOIs), but not both. One group of participants rated the complexity of each sequence (perception). A second group reproduced each sequence on a keyboard and rated the difficulty of production (perception and production). For both dimensions, increasing the number of unique elements in the sequences led to greater perceived complexity, rated difficulty, repetitions, and lower production accuracy. Paradoxically, increases in the number of unique IOIs had a smaller influence on perceived complexity than increases in unique pitches, whereas the opposite effect was found in production. Potential explanations include a perception-action mismatch, and an inferior ability to differentiate between IOIs with increasing temporal complexity.
