Musical Knowledge Influences Auditory Encoding In The Brainstem Marmel, Frederic; Parbery-Clark, Alexandra; Skoe, Erika; Kraus, Nina Auditory Neuroscience Laboratory, Northwestern University (http://www.brainvolts.northwestern.edu/) In Western music, the relations between pitch events are determined by the tonal system. In the last 30 years, a large number of studies have shown that auditory pr...

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...

Chord extraction from audio is a well-established music computing task, and many valid approaches have been presented in recent years that use different chord templates, smoothing techniques and musical context models. The present work shows that additional exploitation of the repetitive structure of songs can enhance chord extraction, by combining chroma information from multiple occurrences o...

Modern collections of symbolic and audio music content provide unprecedented possibilities for musicological research, but traditional qualitative evaluation methods cannot realistically cope with such amounts of data. We are interested in harmonic analysis and propose key-independent chord idioms derived from a bottom-up analysis of musical data as a new subject of musicological interest. In o...

Harmony theory has been essential in composing, analysing, and performing music for centuries. Since Western tonal harmony exhibits a considerable amount of structure and regularity, it lends itself to formalisation. In this paper we present HARMTRACE, a system that, given a sequence of symbolic chord labels, automatically derives the harmonic function of a chord in its tonal context. Among oth...

Expectancy for an upcoming musical chord, harmonic expectancy, is supposedly based on automatic activation of tonal knowledge. Since previous studies implicitly relied on interpretations based on Western music theory, the underlying computational processes involved in harmonic expectancy and how it relates to tonality need further clarification. In particular, short chord sequences which cannot...

A chord diagram consists of a circle, called the backbone, with line segments, called chords, whose endpoints are attached to distinct points on the circle. The genus of a chord diagram is the genus of the orientable surface obtained by thickening the backbone to an annulus and attaching bands to the inner boundary circle at the ends of each chord. Variations of this construction are considered...

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 compare...

This paper proposes a new method for local key and chord estimation from audio signals. A harmonic content of the musical piece is first extracted by computing a set of chroma vectors. Correlation with fixed chord and key templates then selects a set of key/chord pairs for every frame. A weighted acyclic harmonic graph is then built with these pairs as vertices, and the use of a musical distanc...
