Functions

chord_sequence_match_score(seq1, seq2)
Computes the edit distance between two chord sequences to score the extent of the matching between the two sequences between 0 and 1.

source code

chord_sequence_alignment(seq1, seq2, transposition=0)
Performs the same alignment as chord_sequence_match_score, but returns the actual alignment of chords.

chord_sequence_match_score(seq1, seq2)

source code

Computes the edit distance between two chord sequences to score the extent of the matching between the two sequences between 0 and 1.

Each sequence should be a list of jazzparser.data.db_mirrors.Chords. The metric is key-independent. The distance will be tried for every transposition of one of the sequences and the closest match will be used.

chord_sequence_alignment(seq1, seq2, transposition=0)

source code

Performs the same alignment as chord_sequence_match_score, but returns the actual alignment of chords.

The alignment assumes that the first sequence is transposed by transposition.
