A tool for musicological analysis from audio files. Now it is focused on modal music analysis : Scale analysis, tonic detection
Music22 is a Python2 package for musicological analysis, especially modal music and melodies. The analysis is done from audio files.
For now, it’s main features are :
- Fondamental frequencies extraction (using PredominentMelody() from Essentia);
- Getting the main frequencies as peaks of the probability density function from frequencies;
- Comparing PDFs using a correlation coefficient;
- Getting a similarity matrix between melodies.
Then, install Music22 with the following :
pip install music22
Or, if you have a GitLab account, using git:
git clone https://gitlab.com/AnasGhrab/music22 python setup.py install
To use Music22 :
from music22 import modalis,scale path = "path/to/a/folder/with/audios/wav/files/" Kchants = modalis.melodies(path,transpose='Yes',freqref=300)
Then you can
Kchants.pdf_show() Kchants.matrix() Kchants.melodies.scale
