This extended abstract describes a submission to the Music Information Retrieval Evaluation eXchange 2010 (MIREX 2010) in the Audio Chord Estimation and Audio Key Detection tasks. We propose a new model to recognize musical keys and chords simultaneously from musical acoustic signals including key modulations. Chords and keys are closely related notions of music involving harmony. Since occurre...

Only little systematic research has examined event-related brain potentials (ERPs) elicited by the cognitive processing of music. The present study investigated how music processing is influenced by a preceding musical context, affected by the task relevance of unexpected chords, and influenced by the degree and the probability of violation. Four experiments were conducted in which "nonmusician...

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...

Pregroups had been conceived as an algebraic tool to recognize grammatically well-formed sentences in natural languages [3]. Here we wish to use pregroups to recognize well-formed chords of pitches, for a given definition of those chords. We show how a judicious choice of basic and simple types allows a context-free grammatical description. Then we use the robustness property to extend the set ...

We present a computational framework for chord invention based on a cognitive-theoretic perspective on conceptual blending. The framework builds on algebraic specifications, and solves two musicological problems. It automatically finds transitions between chord progressions of different keys or idioms, and it substitutes chords in a chord progression by other chords of a similar function, as a ...

The naturalnessand variety of a touch-based hand gesture interface offers new opportunities for human-computer interaction.Using a new type of capacitive sensor array,a Multi-Touch Surface (MTS) can be createdthat is not limited in size, that can be presented in many configurations, that is robust under a variety of environmental operating conditions, and that is very thin. Typing and gesture r...

We establish an explicit formula for the number of chord diagrams on 2n points with k short chords and compute the expected number of short chords in a chord diagram.

The standard western music notation for the major and minor chords is avail- able in world. But understanding of very difficult learning peoples particularly children’s. It complicated to memory all also roots chords. This inven- tion easily understand by children captured piano other instruments. new method conveying numerical tech- niques used this invention. octave notes are derived two diff...

A carousel is a dynamical system that describes the movement of an equilateral linkage in which the midpoint of each rod travels parallel to it. They are closely related to the floating body problem. We prove, using the work of Auerbach, that any figure that floats in equilibrium in every position is drawn by a carousel. Of special interest are such figures with rational perimetral density of t...
