class GraceNotesConverter(minima_grace_notes_duration_factor=0.12, maxima_grace_notes_duration_factor=0.25, minima_number_of_grace_notes=1, maxima_number_of_grace_notes=4, chronon_to_grace_note_consecution=ChrononToGraceNoteConsecution(), chronon_to_after_grace_note_consecution=ChrononToAfterGraceNoteConsecution())[source]

Bases: EventConverter

Apply grace notes and after grace notes on core_events.abc.Event.

Parameters:

  • minima_grace_notes_duration_factor (float) – Minimal percentage how much of the initial duration of the Chronon shall be moved to the grace notes / after grace notes. This value has to be smaller than 0.5 (so that the Chronon have a duration > 0 if it has both: grace notes and after grace notes) and bigger than 0 (so that the grace notes or after grace notes have a duration > 0). Default to 0.12.

  • maxima_grace_notes_duration_factor (float) – Maxima percentage how much of the initial duration of the Chronon shall be moved to the grace notes / after grace notes. This value has to be smaller than 0.5 (so that the Chronon have a duration > 0 if it has both: grace notes and after grace notes) and bigger than 0 (so that the grace notes or after grace notes have a duration > 0). Default to 0.25.

  • minima_number_of_grace_notes (int) – For how many events in the grace note or after grace note container shall the minima_grace_notes_duration_factor be applied. Default to 1.

  • maxima_number_of_grace_notes (int) – For how many events in the grace note or after grace note container shall the maxima_number_of_grace_notes be applied. Default to 4.

  • chronon_to_grace_note_consecution (Callable[[core_events.Chronon], core_events.Consecution[core_events.Chronon]]) – Function which receives as an input a Chronon and returns a Consecution. By default the function will ask the event for a grace_note_consecution attribute, because by default ~mutwo.music_events.NoteLike objects are expected.

  • chronon_to_after_grace_note_consecution (Callable[[core_events.Chronon], core_events.Consecution[core_events.Chronon]]) – Function which receives as an input a Chronon and returns a Consecution. By default the function will ask the event for a grace_note_consecution attribute, because by default ~mutwo.music_events.NoteLike objects are expected.

class RhythmicalStrataToIndispensability[source]

Bases: Converter

Builds metrical indispensability for a rhythmical strata.

This technique has been described by Clarence Barlow in On the Quantification of Harmony and Metre (1992). The technique aims to model the weight of single beats in a particular metre. It allocates each beat of a metre to a specific value that describes the indispensability of a beat: the higher the assigned value, the more accented the beat.

Public Methods:

convert(rhythmical_strata_to_convert)

Convert indispensability for each beat of a particular metre.
Inherited from Converter

Inherited from MutwoObject

copy()

Return a deep copy of mutwo object.
convert(rhythmical_strata_to_convert)[source]

Convert indispensability for each beat of a particular metre.

Parameters:

rhythmical_strata_to_convert (Sequence[int]) – The rhythmical strata defines the metre for which the indispensability shall be calculated. The rhythmical strata is a list of prime numbers which product is the amount of available beats within the particular metre. Earlier prime numbers in the rhythmical strata are considered to be more important than later prime numbers.

Returns:

A tuple of a integer for each beat of the respective metre where each integer describes how accented the particular beat is (the higher the number, the more important the beat).

Return type:

tuple[int, …]

Example:

>>> from mutwo import music_converters
>>> metricity_converter = music_converters.RhythmicalStrataToIndispensability()
>>> metricity_converter.convert((2, 3))  # time signature 3/4
(5, 0, 3, 1, 4, 2)
>>> metricity_converter.convert((3, 2))  # time signature 6/8
(5, 0, 2, 4, 1, 3)

class PlayingIndicatorConverter(chronon_to_playing_indicator_collection=ChrononToPlayingIndicatorCollection())[source]

Bases: Converter

Abstract base class to apply PlayingIndicator on a Chronon.

Parameters:

chronon_to_playing_indicator_collection (Callable[[core_events.Chronon], music_parameters.PlayingIndicatorCollection], optional) – Function to extract from a mutwo.core_events.Chronon a mutwo.music_parameters.PlayingIndicatorCollection object. By default it asks the Event for its playing_indicator_collection attribute (because by default mutwo.music_events.NoteLike objects are expected). When using different Event classes than NoteLike with a different name for their playing_indicator_collection property, this argument should be overridden. If the function call raises an AttributeError (e.g. if no playing indicator collection can be extracted), mutwo will build a playing indicator collection from DEFAULT_PLAYING_INDICATORS_COLLECTION_CLASS.

To write a new PlayingIndicatorConverter the abstract method _apply_playing_indicator() and the abstract properties playing_indicator_name and default_playing_indicator have to be overridden.

playing_indicator_name

default_playing_indicator
