A Graphical Model for Chord Progressions
ثبت نشده
چکیده
Chord progressions are the building blocks from which tonal music is constructed. Inferring chord progressions is thus an essential step towards modeling long term dependencies in music. In this paper, a distributed representation for chords is designed such that Euclidean distances roughly correspond to psychoacoustic similarities. Graphical models observing chord progressions are then compared in terms of conditional outof-sample likelihood. Both perceptual and statistical evidence show that binary trees related to meter are well suited to capture chord dependencies.

A Probabilistic Model for Chord Progressions
Chord progressions are the building blocks from which tonal music is constructed. Inferring chord progressions is thus an essential step towards modeling long term dependencies in music. In this paper, a distributed representation for chords is designed such that Euclidean distances roughly correspond to psychoacoustic dissimilarities. Estimated probabilities of chord substitutions are derived ...
متن کاملProbabilistic Melodic Harmonization
We propose a representation for musical chords that allows us to include domain knowledge in probabilistic models. We then introduce a graphical model for harmonization of melodies that considers every structural components in chord notation. We show empirically that root notes progressions exhibit global dependencies that can be better captured with a tree structure related to the meter than w...
متن کاملA Computational Model That Generalises Schoenberg’s Guidelines for Favourable Chord Progressions
This paper presents a formal model of Schoenberg’s guidelines for convincing chord root progressions. This model has been implemented as part of a system that models a considerable part of Schoenberg’s Theory of Harmony. This system implements Schoenberg’s theory in a modular way: besides generating four-voice homophonic chord progressions, it can also be used for creating other textures that d...
متن کاملA Unified Probabilistic Model of Note Combinations and Chord Progressions
This paper presents a unified simultaneous and sequential model for note combinations and chord progressions. In chord progression analysis, n-gram models have often been used for modeling temporal sequences of chord labels (e.g., C major, D minor, and E# seventh). These models require us to specify the value of n and define a limited vocabulary of chord labels. On the other hand, our model is ...
متن کاملRealtime Generation of Harmonic Progressions Using Constrained Markov Selection
In this paper, we describe a method of generating harmonic progressions using case-based analysis of existing material that employs a variable-order Markov model. Using a unique method for quantifying harmonic complexity and tension between chord transitions, as well as specifying a desired bass-line, the user specifies a 3 dimensional vector, which the realtime generative algorithm attempts to...
