Struct TurnRecognizer 

pub struct TurnRecognizer {
    pub acceptable_intervals: Vec<Interval>,
}

Recognizes busy notes as a turn: music21’s TurnRecognizer.

Fields

acceptable_intervals: Vec<Interval>

The steps a turn may take: music21’s acceptableIntervals, minor, major and augmented seconds up and down.

Implementations

impl TurnRecognizer

pub fn is_acceptable_interval(&self, step: &Interval) -> bool

Whether a turn may take this step: music21’s isAcceptableInterval.

pub fn recognize( &self, busy: &[StreamElement], simple: &[StreamElement], ) -> Result<Option<Ornament>>

The turn the busy notes play, or nothing: music21’s recognize.

Four notes a second apart, the second and fourth sounding the same pitch, the first two steps one way and the last the other way, are a turn where they start above and an inverted turn where they start below. Given a simple note, it must sound the turn’s main pitch and last as long as the four notes, within a tenth of a quarter.

Errors

A busy note or a simple note that is not a note, as music21 cannot read its pitch.
