Network Analysis of Generalized Musical Spaces
unleashing data tools for music theory, analysis and composition
A python library for pitch class set and rhythmic sequences classification and manipulation, the generation of networks in generalized music and sound spaces, deep learning algorithms for timbre recognition, and the sonification of arbitrary data

There are three example notebooks: basic, advanced harmony, advanced timbre. See the ipynb files for a full description.
musicntwrk is a project written for python 3 and comprised of a main module,
musicntwrk, and many additional helper packages included in the distribution:
musicntwrk- is the main module and contains helper clasess for pitch class set classification and manipulation in any arbitrary temperament (PCSet, PCSetR and PCSrow), and the main class musicntwrk that allows the construction of generalized musical space networks using distances between common descriptors (interval vectors, voice leadings, rhythm distance, etc.); the analysis of scores, the sonification of data and the generation of compositional frameworks.
musicntwrkacts as a wrapper for the various functions organized in the following sub projects:
networks- contains all the modules to construct dictionaries and networks of pitch class set spaces including voice leading, rhythmic spaces, timbral spaces and score network and orchestarion analysis
data- sonification of arbitrary data structures, including automatic score (musicxml) and MIDI generation
timbre- analysis and characterization of timbre from a (psycho-)acoustical point of view. In particular, it provides: the characterization of sound using, among others, Mel Frequency or Power Spectrum Cepstrum Coefficients (MFCC or PSCC); the construction of timbral networks using descriptors based on MF- or PS-CCs
harmony- helper functions for harmonic analysis, design and autonomous scoring
ml_utils- machine learning models for timbre recognition through the TensorFlow Keras framework
plotting- plotting function including a module for automated network drawing
utils- utility functions used by other modules
The most computationally intensive parts of the modules can be run on parallel processors using the MPI (Message Passing Interface) protocol. Communications are handled by two additional modules:
load_balancing. Since the user will never have to interact with these modules, we omit here a detailed description of their functions.
