Construct a dyad

Description

Construct a dyad given one note, an interval, and a direction.

Usage

dyad(
  notes,
  interval,
  reverse = FALSE,
  octaves = c("tick", "integer"),
  accidentals = c("flat", "sharp"),
  key = NULL
)

Arguments

notes	character, a noteworthy string, single notes only, no chords. Number of timesteps must equal the length of interval.
interval	integer or character vector; semitones or interval ID, respectively. See details.
reverse	logical, reverse the transposition direction. Useful when interval is character.
octaves, accidentals, key	See transpose().

Details

The interval may be specified by semitones of by common interval name or abbreviation. See examples. For a complete list of valid interval names and abbreviations see mainIntervals(). key enforces the use of sharps or flats. This function is based on transpose(). notes and interval may be vectors, but must be equal length. Recycling occurs only if one argument is scalar.

Value

character

Examples

dyad("a", 4)
x <- c("minor third", "m3", "augmented second", "A2")
dyad("a", x)
dyad("c'", x, reverse = TRUE)

x <- c("M3", "m3", "m3", "M3", "M3", "m3", "m3")
dyad(letters[c(3:7, 1, 2)], x)

x <- c("P1", "m3", "M3", "P4", "P5", "P8", "M9")
dyad("c", x)
dyad("c", x, reverse = TRUE)
dyad("d e", "m3")
