Structured Training For Large-Vocabulary Chord Recognition

Brian McFee, Juan Pablo Bello
2017 Zenodo  
We hypothesize that leveraging known relationships between chord classes in terms of common roots and shared pitch classes can help mitigate the problem of observation bias, resulting in more accurate  ...  Recently, interest has shifted toward the large-vocabulary regime, where a broader class of chord qualities must be estimated, such as triads, sixths, sevenths, and suspended chords.  ...

MINGUS: Melodic Improvisation Neural Generator Using Seq2Seq

Vincenzo Madaghiele, Pasquale Lisena, Raphael Troncy
2021 Zenodo  
MINGUS relies on two dedicated embedding models (respectively for pitch and duration) and exploits in prediction features such as chords (current and following), bass line, position inside the measure.  ...  We introduce MINGUS, a Transformer-based Seq2Seq architecture for modelling and generating monophonic jazz melodic lines.  ...  The choice of metrics has a crucial impact on the evaluation of generation models, making it necessary to use many metrics at different levels of abstraction to obtain a reliable quality estimation.  ...

String-based methods for tonal harmony: A corpus study of Haydn's string quartets [article]

David R. W. Sears
2020 arXiv   pre-print
Using this taxonomy as a guide, I then present evidence for three principles of tonal harmony -- recurrence, syntax, and recursion -- using a corpus of Haydn string quartets.  ...  This finding suggests that the vocabulary, at 688 symbols, is simply too large to serve as a suitable proxy for the chord vocabularies in theories of harmony.  ...  The estimates of asym fall in a range between −1 and 1, where positive values indicate that chord 2 is the attractor, negative values indicate that chord 1 is the attractor, and 0 indicates bidirectionality  ...

Tonality Estimation In Electronic Dance Music: A Computational And Musically Informed Examination

Ángel Faraldo, Sergi Jordà, Perfecto Herrera
2018 Zenodo  
First, I attempt to detect possible misconceptions within the task, which is typically accomplished with a tonal vocabulary overly centred in Western classical tonality, reduced to a binary major/minor  ...  This dissertation revolves around the task of computational key estimation in electronic dance music, upon which three interrelated operations are performed.  ...  in this period.  ...

Personalized Popular Music Generation Using Imitation and Structure [article]

Shuqi Dai, Xichu Ma, Ye Wang, Roger B. Dannenberg
2021 arXiv   pre-print
To address requirements that challenge current deep learning methods, we propose a statistical machine learning model that is able to capture and imitate the structure, melody, chord, and bass style from  ...  In addition, more application scenarios such as music therapy require imitating more specific musical styles from a few given music examples, rather than capturing the overall genre style of a large data  ...  For melody and chord generation, we used a paired t-test to compare the estimated probability in terms of our multiple rating functions.  ...

2021 arXiv   pre-print
In this article, we aim to provide a review of the key ideas and approaches proposed in 20 years of scientific literature around musical version identification (VI) research and connect them to current  ...  For more than a decade, VI systems suffered from the accuracy-scalability trade-off, with attempts to increase accuracy that typically resulted in cumbersome, non-scalable systems.  ...  For example, most research in automatic chord estimation uses a rather small target vocabulary (24 chords), which is insufficient to correctly transcribe tracks from certain genres (e.g., jazz and blues  ...

Efficient Communication in Written and Performed Music

Laurent Bonnasse-Gahot
2020 Cognitive Science  
We show that there is a clear positive relationship between (contextual) information content of harmonic sequences and two essential musical properties, namely duration and loudness: the more unexpected  ...  However, in spite of the success of the efficient communication framework in the study of language and speech, very little work has investigated its relevance in the analysis of music.  ...  By taking metrical strength into account in our analysis, we show that the information/duration relationship actually holds beyond this possible metrical confound.  ...

A Theory of Tonal Hierarchies in Music [chapter]

Carol L. Krumhansl, Lola L. Cuddy
2010 Springer Handbook of Auditory research  
Variation occurs in the particular intervals formed by pitches in the musical scale and the hierarchical levels assigned to pitches within the scale.  ...  One of the most pervasive structural principles found in music historically and cross-culturally is a hierarchy of tones.  ...  However, this claim resides in a complex theory of tonal-harmonic music and technical vocabulary that would be unknown to nonmusicians.  ...
