A unified probabilistic framework for audio-based chord and tonal key recognition is described and evaluated. The proposed framework embodies an acoustic observation likelihood model and key & chord transition models. It is shown how to conceive these models and how to use music theory to link key/chord transition probabilities to perceptual similarities between keys/chords. The advantage of a ...

An i-chord of a cycle or path is an edge whose endpoints are a distance i ≥ 2 apart along the cycle or path. Motivated by many standard graph classes being describable by the existence of chords, we investigate what happens when i-chords are required for specific values of i. Results include the following: A graph is strongly chordal if and only if, for i ∈ {4, 6}, every cycle C with |V (C)| ≥ ...

Meaning crossword of sound, Crossole is a musical metainstrument where the music is visualized as a set of virtual blocks that resemble a crossword puzzle. In Crossole, the chord progressions are visually presented as a set of virtual blocks. With the aid of the Kinect sensing technology, a performer controls music by manipulating the crossword blocks using hand movements. The performer can bui...

This paper describes a chord recognition system submitted to the MIREX 2009 Audio Chord detection contest. Extracting harmonic information from audio signals has become a topic of keen interest for many researches in Music Information Retrieval (MIR) community. The FBK submission consists of two chord detection system: baseline and the system with language modeling functionality. The two submis...

Received: December 16, 2010 Accepted: December 31, 2010 doi:10.5539/jmr.v3n2p206 Abstract In this paper we investigate product cordial labeling for some new graphs. We prove that the friendship graph, cycle with one chord (except when n is even and the chord joining the vertices at diameter distance), cycle with twin chords (except when n is even and one of the chord joining the vertices at dia...

Generating a chord progression from a monophonic melody is a challenging problem because a chord progression requires a series of layered notes played simultaneously. This paper presents a novel method of generating chord sequences from a symbolic melody using bidirectional long short-term memory (BLSTM) networks trained on a lead sheet database. To this end, a group of feature vectors composed...

Radiation dose estimates to the trabecular region of the skeleton are of primary importance due to recent advancements in nuclear medicine. Establishing methods for accurately calculating dose in these regions is difficult due to the complex microstructure of this anatomic site and the typical ranges of beta-particles in both bone and marrow tissues. At the present time, models of skeletal dosi...

Peer-to-Peer (P2P) systems and P2P Grids are evolving as two viable distributed computing paradigms for wide-area resource sharing on the Internet. To achieve scalable distribution of processing workload among the nodes, large-scale distributed systems such as P2P Grids need to acquire some global information in a fully decentralized fashion. This paper presents efficient schemes for building d...

Massive amount of movement data, such as daily trips made by millions of passengers in a city, are widely available nowadays. They are a highly valuable means not only for unveiling human mobility patterns, but also for assisting transportation planning, in particular for metropolises around the world. In this paper, we focus on a novel aspect of visualizing and analyzing massive movement data,...
