The music we usually listen to in everyday life consists of either single melodies or harmonized melodies (i.e., of melodies "accompanied" by chords). However, differences in the neural mechanisms underlying melodic and harmonic processing have remained largely unknown. Using EEG, this study compared effects of music-syntactic processing between chords and melodies. In melody blocks, sequences ...

We characterize all simple graphs such that each edge is a chord of some cycle. As a consequence, we characterize all simple 2-connected graphs such that, for any two adjacent vertices x and y, the local connectivity k(x, y) ≥ 3. We also make a conjecture about chords for 3-connected graphs.

This article provides an introduction to basic geometric investigations of the 12-tone sytem and its subsets, the chords. The various definitions and results are intended to lay a theoretical basis for 12-tone-based explorative and empirical research on occidental harmony. The entire approach is motivated by the assumption that the 12 tones do not constitute an arbitrary 12-element set with arb...

One test of dichotic listening utilizing nonverbal stimuli is included on the VA-CD Tonal and Speech Materials for Auditory Perceptual Assessment, Disc 1.0. It is a test using three tone complexes that meet the definition of musical chords. The dichotic chords were included as a complement to the three dichotic speech procedures on the VA disc because musical chords may depend on right hemisphe...

Lack of normal mitral leaflet apposition and abnormal pointing of the flail component into the left atrium (LA) during systole are typical features of mitral leaflet flail which generate haemodynamically relevant mitral regurgitation (MR). The most common reason for mitral leaflet flail is chord rupture. Rarely, severe prolapse with the leaflet tip bulging into the LA causing severe MR can also...

The Heisenberg evolution of a given unitary operator corresponds classically to a fixed canonical transformation that is viewed through a moving coordinate system. The operators that form the bases of the Weyl representation and its Fourier transform, the chord representation, are, respectively, unitary reflection and translation operators. Thus, the general semiclassical study of unitary opera...

BACKGROUND Music-syntactic irregularities often co-occur with the processing of physical irregularities. In this study we constructed chord-sequences such that perceived differences in the cognitive processing between regular and irregular chords could not be due to the sensory processing of acoustic factors like pitch repetition or pitch commonality (the major component of 'sensory dissonance'...
