Enum ChordWeight 

pub enum ChordWeight {
    Length,
    LengthByBeat,
    LengthByBeatInMeasure,
    Consonance,
}

How much a chord weighs in its measure: music21’s four weight algorithms, one of which its ChordReducer hands to computeMeasureChordWeights.

Variants

Length

How long the chord sounds, and nothing else: music21’s quarterLengthOnly, which is what computeMeasureChordWeights weighs by when it is handed none.

LengthByBeat

That times how strong its beat is: quarterLengthBeatStrength.

LengthByBeatInMeasure

The same, except that the last chord of the measure counts as a full beat: quarterLengthBeatStrengthMeasurePosition.

Consonance

The same again, a tenth of it where the chord is dissonant: qlbsmpConsonance, which is the one a reduction weighs by.

Implementations

impl ChordWeight

pub fn name(self) -> &'static str

The name music21 gives the method.

pub fn named(name: &str) -> Option<Self>

What a name stands for, which is how a caller handing music21’s own method over is read.

pub fn of( self, chord: &Chord, length: FloatType, beat_strength: FloatType, last_in_measure: bool, ) -> FloatType

How much one chord weighs under this algorithm.
