QuantizedBeat

class maelzel.scoring.quant.QuantizedBeat(divisions, assignedSlots, notations, beatDuration, beatOffset=Fraction(0, 1), quantizationError=0.0, quantizationInfo='', weight=0)

Bases: object

A QuantizedBeat holds notations inside a beat filling the beat

Parameters:

• divisions (tuple[int, ...]) – The division of this beat

• assignedSlots (list[int]) – Which slots are assigned to notations in this beat

• notations (list[Notation]) – The notations in this beat. They are cropped to fit

• beatDuration (Fraction) – The duration of the beat in quarter notes

• beatOffset (Fraction) – The offset of the beat in relation to the measure

• quantizationError (float) – The error calculated during quantization. The higher the error, the less accurate the quantization

• quantizationInfo (str) – Info collected during quantization

• weight (int) – The weight of this beat within the measure. 2=strong, 1=weak, 0=no weight
