Algorithms¶
This module allows to extract, modify and predict different aspects of a music piece.
Harmonic Shifting¶
|
This function maps the pitches of a midi to a new scale and chord progression. |
Key-Profiles¶
State of the Art algorithms for key finding in symbolic music. The key-profiles weights in the library are the following:
