har_19_composite: Composite consonance model

In pmcharrison/incon: Computational Models of Simultaneous Consonance

Composite consonance model

Description

This function computes the consonance of a chord according to Harrison & Pearce's (in preparation) composite consonance model.

Usage

har_19_composite(x, chord_size = FALSE, num_harmonics = 11L, roll_off = 1)

Arguments

x	Chord to analyse; passed to incon. All chord pitches must be integer-valued.
chord_size	(Boolean) Whether to include the chord size effect (see Details).
num_harmonics	(Integerish scalar) Number of harmonics in each tone; passed to incon.
roll_off	(Numeric scalar) Harmonic roll-off rate; passed to incon.

Details

The model combines several sub-models:

• hutch_78_roughness, the roughness model of \insertCiteHutchinson1978;textualincon (see incon::roughness_hutch);

• har_18_harmonicity, the harmonicity model of \insertCiteHarrison2018;textualincon (see incon::pc_harmonicity);

• har_19_corpus: a corpus-based model of cultural familiarity (Harrison & Pearce, in preparation) (see incon::corpus_dissonance).

This model uses the regression coefficients provided in har_19_composite_coef, with one caveat: by default, the chord size effect is disabled, because it's thought that this effect came from a confound in the perceptual data of \insertCiteBowling2018;textualincon.

Value

Estimated consonance, as a numeric scalar.
