rekey {schoenberg}

Re-express a "schoenberg" class object with a different lead tone or different notation of accidentals.

Description

Re-express a "schoenberg" class object with a different lead tone or different notation of accidentals.

Usage

rekey(tone_mat, tone0 = NULL, accidentals = NULL)

Arguments

tone_mat

Object of the class "schoenberg" produced by the schoenberg() function.

tone0

Optional: Name of the note to use as the lead tone of the matrix.

accidentals

Optional: Character scalar that determines whether accidentals should be represented as sharps (accidentals = "sharps") or flats (accidentals = "flats"); default value is NULL. accidentals can also be set to "integers" when one wishes to obtain a 12-tone matrix of numeric indices rather than notes. When accidentals is NULL, matrices created from pre-specified vectors of notes will use the original set of accidentals, whereas random matrices and matrices created from vectors of numeric indices will default to sharp notation.

Value

A 12-tone matrix of the "schoenberg" class with prime series on the rows and inverted series on the columns.

Examples

# Let's create a vector of notes to use in creating our inital 'tone_mat' matrix based
# on Schoenberg's Walzer from Opus 23
prime01 <- c("C#", "A", "B", "G", "Ab", "F#", "A#", "D", "E", "Eb", "C", "F")
tone_mat <- schoenberg(prime0 = prime01)

# Now, let's change the lead tone to "C":
rekey(tone_mat = tone_mat, tone0 = "C")

# And let's also change the accidentals to flats:
rekey(tone_mat = tone_mat, tone0 = "C", accidentals = "flats")
