Method Details

[hide private]

test_back_conversion(self)

source code

Creates a tonal space path, converts it to state labels and converts it back again. This should produce the original path if all goes well.

Note that the result of the back conversion will always have the path shifted so it starts as close as possible to the origin. This is correct behaviour: the state labels don't encode the enharmonic block that the path starts in and it is merely by convention that we assume the start point.

Each path-chord sequence pair also gives the expected output, which may differ from the original path only in this respect.

To Do: update this test
