Harmony perception by periodicity detection
This article consistently applies recent results from psychophysics and neuroacoustics, namely that the just noticeable difference between two pitches for humans is about 1% for the musically important low frequency range and that periodicities of complex chords can be detected in the human brain.
A PERIODICITY-BASED APPROACH ON HARMONY PERCEPTION INCLUDING NON-WESTERN SCALES Frieder Stolzenburg Harz
- Computer Science
It seems that both the perception of chords and scales in any music obey similar principles, namely that simpler patterns with short period lengths are preferred by humans.
A Bi-Directional Transformer for Musical Chord Recognition
- Computer ScienceISMIR
It turns out that the proposed bi-directional Transformer for chord recognition was able to divide segments of chords by utilizing adaptive receptive field of the attention mechanism, and it was observed that the model was ability to effectively capture long-term dependencies, making use of essential information regardless of distance.
Modeling Temporal Tonal Relations in Polyphonic Music Through Deep Networks With a Novel Image-Based Representation
- Computer ScienceAAAI
Experimental results show that the tonnetz representation produces musical sequences that are more tonally stable and contain more repeated patterns than sequences generated by pianoroll-based models, a finding that is directly useful for tackling current challenges in music and AI such as smart music generation.
A Hierarchical Harmonic Mixing Method
We present a hierarchical harmonic mixing method for assisting users in the process of music mashup creation. Our main contributions are metrics for computing the harmonic compatibility between…
A Perceptually-Motivated Harmonic Compatibility Method for Music Mixing
- Computer Science
An evaluation of the harmonic compatibility method shows that it complies with the principles embodied in Western tonal harmony to a greater extent than previous approaches.
Algebra of Harmony: Transformations of Just Consonances
A graphical representation of the complete neighborhood of a harmony, called ‘neighborhood network,’ is presented along with several simpler and more complex examples, which enable a deeper analysis of harmonic ’neighbourhoods.
Automatic musical key estimation with adaptive mode bias
- Computer Science2017 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)
Results demonstrate the effectiveness of the mode bias in favoring either the major or minor mode, thus allowing users to fine tune this variable to improve correct key estimates on style-specific music datasets or to balance predictions across key modes on unknown input sources.
Bodily Interactions in Motion-Based Music Applications
- Art, Computer Science
A framework for the design and the assessment of motion-based music applications is proposed by involving outcomes from various disciplines, such as the cognitive sciences and human–computer interaction, to determine their relationships and to discuss related design issues.
Modelling tonal attraction: tonal hierarchies, interval cycles, and quantum probabilities
- PhysicsSoft Comput.
It is argued that the quantum approach integrates the insights from both group theory and quantum probability theory and achieves a deeper understanding of the cognitive nature of tonal music, especially concerning the nature of musical expectations and a betterUnderstanding of the affective meaning of music.
