vl_dist: How far apart are two scales?

In musicMCT: Analyze the Structure of Musical Scales

How far apart are two scales?

Description

Using the chosen method to measure distance, determines how far apart two scales are in voice-leading space.

Usage

vl_dist(
  set_1,
  set_2,
  method = c("taxicab", "euclidean", "chebyshev", "hamming"),
  rounder = 10
)

Arguments

set_1, set_2	Numeric vectors of pitch-classes in the sets. Must be of same length.
method	What distance metric should be used? Defaults to "taxicab" but can be "euclidean", "chebyshev", or "hamming".
rounder	Numeric (expected integer), defaults to 10: number of decimal places to round to when testing for equality.

Value

Numeric: distance between set_1 and set_2

Examples

c_major <- c(0, 4, 7)
a_minor_63 <- c(0, 4, 9)
f_minor_64 <- c(0, 5, 8)
vl_dist(c_major, a_minor_63)
vl_dist(c_major, f_minor_64)
vl_dist(c_major, a_minor_63, method="euclidean")
vl_dist(c_major, f_minor_64, method="euclidean")
