Human music perception is related both to musical experience and the physical properties of sound. Examining the processing of music by nonhuman animals has been generally neglected. We tested both black-capped chickadees and humans in a chord discrimination task that replicates and extends prior research with pigeons. We found that chickadees and humans, in common with pigeons, showed similar ...

Listeners judged whether two sequentially presented major chords were the same. When both chords were based on the same root, listeners discriminated between different chord positions, e.g., root position, first inversion, second inversion. The ability of listeners to discriminate between chord positions suggests that harmonic equivalence of different chord positions does not depend on perceptu...

What role does item similarity play in motor skill acquisition? To examine this question, we used a modified version of the chord learning task (Seibel, 1963) that entails producing simultaneous finger key presses, similar to playing a chord on a piano. In Experiment 1, difficulty, as indexed by response time (RT) to a particular chord on the first session, was held constant, and chords that we...

Rolled or arpeggiated chords are notated chords performed by playing the notes sequentially, usually from lowest to highest in pitch. Arpeggiation is a characteristic of musical expression, or expressive timing, in piano performance. However, very few studies have investigated rolled chord performance. In this paper, we investigate two expressive timing properties of piano rolled chords: equiva...

OBJECTIVE To analyze left ventricular (LV) regional wall motion in patients with endomyocardial fibrosis (EMF). METHODS The study comprised 88 patients, 59 of the female sex, with a mean age of 39+/-13 years (range, 9 to 65) and with echocardiographic and angiographic evidence of left ventricular EMF. The intensity of fibrous tissue buildup on contrast cineventriculography was classified as m...

Sensory consonance and dissonance are perceptual attributes of musical intervals conveying pleasantness, tension, and harmony in musical phrases. For complex-tone dyads, corresponding to two musical notes played simultaneously, consonance is known to vary with the ratio in fundamental frequency (F0) between the two tones in the dyad. While such a relationship is well established for dyads, the ...
