scamp_extensions.composers.barlicity
Module containing implementations of many of Clarence Barlow’s theoretical constructs. These include:
Indigestibility
Harmonicity (including harmonicity-based scale rationalization)
Rhythmic indispensability
Metric Coherence
All of these are described in his book, “On Musiquantics”. (http://clarlow.org/wp-content/uploads/2016/10/On-MusiquanticsA4.pdf)
Functions
|
Calculates the "metric coherence" of two meters, as described on pages 46-47 of Barlow's "On Musiquantics". |
|
As Barlow explains on page 46 of "On Musiquantics," the metric coherece of a meter with itself is not always 1. |
|
A slightly more general approach to indispensability than the one proposed by Barlow. |
|
Returns a list of the indispensabilities of different pulses in a meter defined by the rhythmic_strata. |
|
Returns a number representing the simplicity (and thereby a kind of consonance) of an interval with frequency ratio of p/q. |
Returns a number representing how hard it is for a human to divide an object (e.g. |
|
|
Uses Clarence Barlow's algorithms for scale rationalization to determine optimal rational tunings given an input scale in cents values. |
