Struct TrillRecognizer 

pub struct TrillRecognizer {
    pub check_nachschlag: bool,
    pub acceptable_interval: IntegerType,
    pub minimum_length_for_nachschlag: usize,
}

Recognizes busy notes as a trill: music21’s TrillRecognizer.

Fields

check_nachschlag: bool

Whether the last notes may leave the trill as a nachschlag: music21’s checkNachschlag.

acceptable_interval: IntegerType

The most semitones the two trilled notes may be apart: acceptableInterval.

minimum_length_for_nachschlag: usize

The fewest busy notes a trill with a nachschlag may have: minimumLengthForNachschlag.

Implementations

impl TrillRecognizer

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

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

More than two notes, alternating between two pitches no more than TrillRecognizer::acceptable_interval apart, are a trill up from the first, or down where the second is lower; with TrillRecognizer::check_nachschlag, the second half may leave the alternation. Given a simple note sounding one of the two pitches, the trill is from that pitch to the other. Each trilled note lasts as long as ornament_note_quarter_length says, and the trill is spelled with the accidental of the note it goes to.

Errors

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