Duration

Duration Class

Namespace: CW.Soloist.CompositionService.MusicTheory
Assembly: CW.Soloist.CompositionService.dll

Summary

Represents a duration of a musical component such as a note or chord.

internal class Duration : IDuration

Implements IDuration

---

Remarks

Each duration is assembled of two properties:
Numerator, which represents the number of beats in the duration,
and Denominator, which represents the duration of a single beat, in relation to whole note duration.
For example, a chord which is played over half a bar, would have a duration of 1/2.

Duration of notes and chords are calculated as the quotient of the nominator divided by the denominator,
so for example, a duration instance of 2/4 is equivalent to 1/2.

Constructors

Signature	Description
Duration(byte,byte,bool)	Constructs a duration based on a numerator and a denominator.
Duration(IDuration,bool)	Constructs a duration based on an existing duration.

Properties

Property Name	Type	Description
Numerator	byte	Number of beats in the duration.
Denominator	byte	Length of the beat in relation to a whole note duration.
Fraction	float	Quotient of the division of the duration's numerator by the duration's denominator.

Methods

Method Name	Return Type	Description
Add	IDuration	Adds the given duration to this duration, and returns the sum.
Subtract	IDuration	Subtracts the given duration from this duration, and returns the difference.
IsDenominatorPowerOfTwo	bool	Determines whether this duration's denominator is a power of two or not.
ToString	string	Returns a string that represents the current duration.
GreatestCommonDivisor	int	Returns GCD of two given natural numbers.

Operators

This class overrides the following comparison operators: '<=', '>=', '<' and '>',
so these can be used to compare the length of a given duration instance to another.
