A chord diagram is a set of chords of a circle such that no pair of chords has a common endvertex. A pair of chords is called a crossing if the two chords intersect. A chord diagram E is called nonintersecting if E contains no crossing. For a chord diagram E having a crossing S = {x1x3, x2x4}, the expansion of E with respect to S is to replace E with E1 = (E \S)∪{x2x3, x4x1} or E2 = (E \S)∪{x1x...

Objectives: Recent studies with event-related brain potentials (ERPs) investigating music processing found (early) negativities with righthemispheric predominance as a response to inappropriate harmonies within sequences of chords. The stimuli used in those studies were fairly artificial in order to control the experimental factors (e.g. variations in tempo and loudness were eliminated). This r...

This paper describes HarmonyMixer, a method that enables a user without musical expertise to personalize the mood of existing polyphonic musical recordings by modifying their chord sequences. Our method lets the user choose a reference songwith a character that the user wants reflected in chords of a target song. It is, however, difficult to modify chords in existing complex sound mixtures sinc...

Perception of dichotic chords (free recall and directed recall), nonsense syllables (CVs), and three-pair digits was assessed on 24 musicians and 24 nonmusicians. On the dichotic-CV and dichotic-digit free-recall tasks, there was a significant right-ear advantage, but there were no group differences. With the dichotic-chords, free-recall condition, a significant left-ear advantage was observed ...

The ability to appreciate most Western music presupposes cognitive structures capable of abstracting an underlying harmonic structure from a complex string of musical events. In this paper we provide a description of the listener’s knowledge of hierarchies of harmonic stability. The organization of harmonic information may be summarized by Osix principles. Three of these ;vrinciples--Key Member...

This paper discusses 2-dimensional locally Euclidean geometries and how these geometries can describe musical chords.

OBJECTIVES To determine whether early administration of captopril lessens infarct zone regional wall motion abnormalities when infarct artery blood flow is abnormal. BACKGROUND The interaction between angiotensin-converting enzyme (ACE) inhibitor therapy, ventricular function and infarct artery blood flow has not been well described. METHODS A total of 493 patients aged < or = 75 years with...

A long unichord in a graph is an edge that is the unique chord of some cycle of length at least 5. A graph is long-unichord-free if it does not contain any long-unichord. We prove a structure theorem for long-unichord-free graph. We give an O(nm)-time algorithm to recognize them. We show that any long-unichord-free graph G can be colored with at most O(ω) colors, where ω is the maximum number o...

In this paper, a piano chords detector based on parallel interference cancellation (PIC) is presented. The proposed system makes use of the novel idea of modeling a segment of music as a third generation mobile communications signal, specifically, as a CDMA (Code Division Multiple Access) signal. The proposed model considers each piano note as a CDMA user in which the spreading code is replaced...

The authors present a new routing model for over-the-cell channel routing. A graph theoretical algorithm is then proposed to solve the new problem. The algorithm has a complexity of O(nk2), where n is the number of nets and k is the number of columns in the channel. It achieved a routing area reduction of 71.5% for the PRIMARY 1 benchmark example from MCNC, using three-layer over-the-cell routi...
