get_tonal_space_path(self, rank=0)

source code

This is the main interface method.

Parameters:

rank - the rank of the path the get, where 0 is the highest ranked path

Returns: jazzparser.formalisms.base.semantics.lambdacalc.Semantics subclass instance

the rankth highest ranked path through the tonal space for this sequence. Returns None if there is no path with this rank.

Overrides: base.BackoffBuilder.get_tonal_space_path
