Markov model for music generation
Usage:
- Building the corpus
Creates a new folder (destination_dataset_folder) containing transpositions of any midi file on the original_data_folder
python transpose_to_C_or_Am.py original_data_folder destination_dataset_folder
or
python transpose_all_keys.py original_data_folder destination_dataset_folder
- Extracting transition matrix
Analyze of all midi files in all subfolders of dataset_folder and creates two files on the dataset_folder folder, init_symbols.p and symbol_transition_count.p
python extract_matrix.py dataset_folder
- Generate new harmony
python sequence_generator.py dataset_folder output_file_name.mid number_of_chords
