predominantmelodymakam

Predominant melody extraction for makam music

This repository hosts the the implementation of the predominant melody extraction proposed for makam music in:

Atlı, H. S., Uyar, B., Şentürk, S., Bozkurt, B., and Serra, X. (2014). Audio feature extraction for exploring Turkish makam music. In Proceedings of 3rd International Conference on Audio Technologies for Music and Media, Ankara, Turkey.

If you are using this extractor please cite the above paper.

The extractor is based on the methodology by [2]. The contour selection step in [2] is trained on the specfic characteristics of Western pop music and jazz. We remove this step and use a simplified contour selection step by selecting the longest contour at each time instance and discarding all other contours. Then we use the method proposed in [3] to remove the erroneous pitch estimations and correct octave errors.

Usage

from predominantmelodymakam.PredominantMelodyMakam import PredominantMelodyMakam
extractor = PredominantMelodyMakam()
results = extractor.run(audiofile)

Please refer to demo.ipynb for an interactive demo.

Installation

If you want to install the repository, it is recommended to install the package and dependencies into a virtualenv. In the terminal, do the following:

virtualenv env
source env/bin/activate
python setup.py install

If you want to be able to edit files and have the changes be reflected, then install the repo like this instead

pip install -e .

The algorithm uses several modules in Essentia. Follow the instructions to install the library. Then you should link the python bindings of Essentia in the virtual encironment:

ln -s /usr/local/lib/python2.7/dist-packages/essentia env/lib/python2.7/site-packages

Finally you can install the rest of the dependencies:

pip install -r requirements

Changelog

  • Refactored the code to comply with PEP8

Acknowledgements

We would like to thank Dr. Robert Grafias for allowing us to use his makam music collection in our research (in this repository the recording with MBID: d2731692-626d-4a6d-9b67-a70c9e7b9745).
