stochastic_fugue: Generate a stochastic fugue based on Markov chains

In shill1729/synthesizer: Synthesize sounds, melodies, chords, and stochastic compositions

Description

Three Markov chains are generated to model an outline of a fugue, i.e. the path of the subject through different voices, keys, and transformations. Then counterpoint is filled in on each statement for the other voices. Random harmonics are used.

Usage

stochastic_fugue(
  subject,
  rhythms,
  N,
  registers,
  transition_matrices,
  subjectKeys,
  answerKeys,
  keySig = "major"
)

Arguments

subject	the fugue subject, a vector of midi numbers in 0-127
rhythms	the rhythms, either constant or variable
N	the number of statements to generate
registers	the registers of each voice
transition_matrices	a list of transition matrices, see details
subjectKeys	the state space for keys of the subject
answerKeys	the state space for the keys of the answers
keySig	the key signature of the subject

Details

transition_matrices must be a list of four probability transition matrices:

• P.voice

• P.transform

• P.key

• P.answer

Value

vector
