This paper describes a method that identifies musical chords in polyphonic musical signals. As musical chords mainly represent the harmony of music and are related to other musical elements such as melody and rhythm, we should be able to recognize chords more effectively if this interrelationship is taken into consideration. We use bass pitches as clues for improving chord recognition. The prop...

In this paper, we present a family of novel P2P routing schemes based on Chord [26] (and its variation FChord(α) [2]) that trades off uniformity with efficiency without using any additional overhead. We prove that H-FChord(α)’s routing is more efficient than in F-Chord(α) in terms of its average path length that is O(logn/ log logn). We also show, by simulations, that H-F-Chord(α) is more effic...

In this paper we propose an abstract model dedicated to the performance management of the Chord peer-to-peer framework. It captures information about a Chord community, the associated resources, the participating elements, as well as the global performance of the instantiated services. Our model enables the evaluation of the global health state of a Chord community and to act consequently.

We give necessary and sufficient conditions for a weight system on multiloop chord diagrams to be obtainable from a metrized Lie algebra representation, in terms of a bound on the ranks of associated connection matrices. Here a multiloop chord diagram is a graph with directed and undirected edges so that at each vertex, precisely one directed edge is entering and precisely one directed edge is ...

This paper describes a method that recognizes musical chords from real-world audio signals in compact-disc recordings. The automatic recognition of musical chords is necessary for music information retrieval (MIR) systems, since the chord sequences of musical pieces capture the characteristics of their accompaniments. None of the previous methods can accurately recognize musical chords from com...

The Chord distributed hash table (DHT) is well-known and frequently used to implement peer-to-peer systems. Chord peers find other peers, and access their data, through a ring-shaped pointer structure in a large identifier space. Despite claims of proven correctness, i.e., eventual reachability, formal modeling has shown that the Chord ring-maintenance protocol is not correct under its original...

Our research project investigated the effect of background and stimuli factors on relative salience chord-type chord-voicing changes. Earlier studies have shown that surface features tend to be easier perceive than deeper musical training attenuates this general tendency. For further studying how deeper-level surface-level are perceived, we used a two-oddball paradigm. Each item consisted succe...
