A Probabilistic Framework for Audio-Based Tonal Key and Chord Recognition
نویسندگان
چکیده
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 theory based model is that it does not require any training, and consequently, that its performance is not affected by the quality of the available training data.

Tonality Visualization of Polyphonic audio
This paper presents a tool to visualize the tonal content of polyphonic audio signals. After a brief introduction to the problem of tonal analysis, we present different views that can help to analyze the tonal content of a piece of music in audio format and to investigate techniques for chord and key estimation and tonal similarity.
متن کاملA Model for the Perception of Tonal Melodies
This paper presents a concise description of OPTM, a computational model for the On-line Processing of Tonal Melodies. It describes the processes a listener executes when transforming a tone sequence into a tonal melody. The model is based on the assumption that a tone sequence is represented in terms of a chord progression underlying the sequence. Chord tones are directly coded in the harmonic...
متن کاملA Dynamical Model of Pitch Memory Provides an Improved Basis for Implied Harmony Estimation
Tonal melody can imply vertical harmony through a sequence of tones. Current methods for automatic chord estimation commonly use chroma-based features extracted from audio signals. However, the implied harmony of unaccompanied melodies can be difficult to estimate on the basis of chroma content in the presence of frequent nonchord tones. Here we present a novel approach to automatic chord estim...
متن کاملDynamic processes in music perception.
A schema-based theory of music perception that describes the dynamic interaction between the musical event and the listener's knowledge of the underlying regularities in tonal music is proposed. Three properties of musical schema are evaluated in a recognition memory experiment: (1) The schema engages a subset of the abstract knowledge system that is determined by the predominant key of the mus...
متن کاملAutomatic Key Partition Based on Tonal Organization Information of Classical Music
Key information is a useful information for tonal music analysis. It is related to chord progressions, which follows some specific structures and rules. In this paper, we describe a generative account of chord progression consisting of phrase-structure grammar rules proposed by Martin Rohrmeier. With some modifications, these rules can be used to partition a chord symbol sequence into different...
