Documentation

data Beat a Source #

A rhythm is represented as a rose tree where each subtree is given equal amounts of time. Leaves are either a Beat of type a or empty (a rest).

Constructors

Rest

Instances

class SummaryChar a where Source #

Class for things that can be summarized in a single character, for use in printing out rhythms.

Methods

rockBeat :: Beat DrumRack Source #

The standard rock beat (or half of it) played on the DrumRack

primeBeat :: Beat a -> Beat a Source #

Force there to be only prime divisions of time in the rhythm. This is done without affecting the actual rhythm. This operation is not uniquely valued in any way, and this algorithm prefers small primes first.
