pitchtools.MelodicChromaticIntervalSegment

class abjad.tools.pitchtools.MelodicChromaticIntervalSegment.MelodicChromaticIntervalSegment.MelodicChromaticIntervalSegment(*args, **kwargs)

New in version 2.0.

Abjad model of melodic chromatic interval segment:

abjad> pitchtools.MelodicChromaticIntervalSegment([11, 13, 13.5, -2, 2.5])
MelodicChromaticIntervalSegment(+11, +13, +13.5, -2, +2.5)

Melodic chromatic interval segments are immutable.

MelodicChromaticIntervalSegment.slope

The slope of a melodic interval segment is the sum of its intervals divided by its length:

abjad> pitchtools.MelodicChromaticIntervalSegment([1, 2]).slope
Fraction(3, 2)

Return fraction.

MelodicChromaticIntervalSegment.spread

The maximum harmonic interval spanned by any combination of the intervals within a harmonic chromatic interval segment:

abjad> pitchtools.MelodicChromaticIntervalSegment([1, 2, -3, 1, -2, 1]).spread
HarmonicChromaticInterval(4)
abjad> pitchtools.MelodicChromaticIntervalSegment([1, 1, 1, 2, -3, -2]).spread
HarmonicChromaticInterval(5)

Return harmonic chromatic interval.

Methods

MelodicChromaticIntervalSegment.count(value) → integer -- return number of occurrences of value
