DeepBach: a Steerable Model for Bach Chorales Generation [article]

Gaëtan Hadjeres and François Pachet and Frank Nielsen
2017 arXiv   pre-print
This paper introduces DeepBach, a graphical model aimed at modeling polyphonic music and specifically hymn-like pieces.  ...  Our model is also steerable in the sense that a user can constrain the generation by imposing positional constraints such as notes, rhythms or cadences in the generated score.  ...  It is an integer between 1 and 4: there is no distinction between beats in a bar so that our model is able to deal with chorales with three and four beats per measure.  ...

Deep Learning-Based Automatic Downbeat Tracking: A Brief Review [article]

Bijue Jia, Jiancheng Lv, Dayiheng Liu
2019 arXiv   pre-print
Previous researches either focus on feature engineering (extracting certain features by signal processing, which are semi-automatic solutions); or have some limitations: they can only model music audio  ...  Despite significant research efforts, downbeat tracking still remains a challenge.  ...  Hidden Markov Model Hidden Markov Model (HMM) is a probability model with respect to time series.  ...

BREVE: An HMPerceptron-Based Chord Recognition System [chapter]

Daniele P. Radicioni, Roberto Esposito
2010 Studies in Computational Intelligence  
Tonal harmony analysis is a sophisticated task.  ...  The solution proposed to the problem relies on a conditional model, where domain knowledge is encoded in the form of Boolean features.  ...  Raphael & Stoddard [24] proposed a machine learning approach based on a Hidden Markov Model that computes Roman numeral analysis (that is, the higher level, functional analysis mentioned above).  ...

Combining Harmony-Based And Novelty-Based Approaches For Structural Segmentation

Johan Pauwels, Florian Kaiser, Geoffroy Peeters
2013 Zenodo  
Recently however, this approach has been extended to also include contrast between a homogeneous and a non-homogeneous section [6] .  ...  Additionally, the combined system is also less sensitive to the choice of relative chord models than the harmony-based method is.  ...

Improving Music Genre Classification Using Automatically Induced Harmony Rules

Amélie Anglade, Emmanouil Benetos, Matthias Mauch, Simon Dixon
2010 Journal of New Music Research  
We present a new genre classification framework using both low-level signal-based features and high-level harmony features.  ...  A state of-the-art statistical genre classifier based on timbral features is extended using a first-order random forest containing for each genre rules derived from harmony or chord sequences.  ...  Acknowledgements This work was done while the third author was a Research Student at Queen Mary, University of London.  ...

A Functional Taxonomy of Music Generation Systems

Dorien Herremans, Ching-Hua Chuan, Elaine Chew
2017 ACM Computing Surveys  
This design-centered approach contrasts with predominant methods-based surveys and facilitates the identification of grand challenges to set the stage for new breakthroughs.  ...  We present a functional taxonomy for music generation systems with reference to existing systems. The taxonomy organizes systems according to the purposes for which they were designed.  ...  At each point, a decision is made, based on a second-order Markov model, to invert melodic fragments based on the chord, or to copy the previous one.  ...

Automatic Detection of Hierarchical Structure and Influence of Structure on Melody, Harmony and Rhythm in Popular Music

Shuqi Dai, Huan Zhang, Roger Dannenberg
2020 Zenodo  
Repetition is a basic indicator of musical structure. This study introduces new algorithms for identifying musical phrases based on repetition.  ...  Phrases combine to form sections yielding a two-level hierarchical structure.  ...  We introduced a new hierarchical structure analysis algorithm. With it, we analyzed harmony, melody and rhythm in the context of multi-level structure.  ...

2004 Computer Music Journal  
The analysis is performed with a hidden Markov model and, as such, is automatically trainable from generic MIDI files and capable of finding the globally optimal harmonic labeling.  ...  An extension to a more complex probabilistic graphical model is outlined in which music is modeled as a collection of voices that evolve independently given the harmonic progression.  ...  We model this sequence probabilistically as a homogeneous Markov chain r $ &s t! u v w s x ¨ s t! ) y¡ r $ es t! ¨u w s t!  ...

A geometrical distance measure for determining the similarity of musical harmony

W. Bas de Haas, Frans Wiering, Remco C. Veltkamp
2013 International Journal of Multimedia Information Retrieval  
The distance function we present, the Tonal pitch step distance, is based on a cognitive model of tonality and captures the change of harmonic distance to the tonal center over time.  ...  Furthermore, we demonstrate in a case study how our harmonic similarity measure can contribute to the musicological discussion of the melody and harmony in large-scale corpora.  ...  The authors use a Markov model to model the transition distributions between these vectors for every piece.  ...

Cyril Joder, Slim Essid, Gaël Richard
2011 IEEE Transactions on Audio, Speech, and Language Processing  
This strategy reduces the complexity, yielding a better overall efficiency than the classic beam search method used in HMM-based models.  ...  Three types of features are used, characterizing the local harmony, note attacks and tempo.  ...  The use of averaged observations is musically justified since the harmony (and thus the chroma information) is in general homogeneous over a whole beat (or measure) duration.  ...
