Struct FigureTuple 

pub struct FigureTuple {
    pub deg_from_ref_pitch: u8,
    pub alter: FloatType,
    pub prefix: String,
}

Reads a chord as the tonic or the dominant of a key, with its inversion: A pitch as a figure over a reference pitch: the scale step it stands above the reference, how far it is altered from the key’s own spelling of that degree, and the accidental written in front of a figure for it. music21’s FigureTuple.

Fields

deg_from_ref_pitch: u8

The generic step above the reference pitch, 1 to 7.

alter: FloatType

Semitones away from the key’s own spelling of the degree.

prefix: String

The accidental written in front of a figure for it: #, b, ## and so on, or nothing.

Implementations

impl FigureTuple

pub fn from_pitch_and_reference( pitch: &Pitch, key: &Key, reference: &Pitch, ) -> Result<Self>

The figure of pitch above reference in key: music21’s FigureTuple.fromPitchAndReference. An A-3 above an F#2 bass in C major is a third above the bass and a semitone below the A C major has, so it is 3, altered by -1, written b. A minor key is read as the natural minor.
