The sound of the chords

Consonances & dissonances

Description

A list of the perfect & imperfect consonances, and the regular or irregular dissonances
Any interval of two simultaneous tones can give a chord.
As we have already seen, the intervals can be classified into two different categories: consonances and dissonances.
The simple intervals are smaller than an octave and the doubled intervals are larger than an octave.
There are also perfect and imperfect consonances.
Imperfect consonances include: the minor third, major third, minor sixth and major sixth.
The Perfect consonances are: the perfect fourth, perfect fifth, the unison and the perfect octave.
The doubled imperfect consonances have the same characteristics: the third becomes a minor tenth, the major third becomes a major tenth, the minor sixth becomes a minor thirteenth and the major sixth becomes a major thirteenth.
The doubled perfect consonances adopt the same principle: the perfect fourth becomes a perfect eleventh, the perfect fifth a perfect twelfth, the perfect unison becomes a perfect octave and the perfect octave becomes a perfect double octave.
It is the same for the dissonances that make real chords: the minor second, major second, minor seventh and major seventh, but also: the augmented fourth, the diminished fifth, the minor ninth and major ninth.
The augmented eleventh is a doubled augmented fourth, the diminished eleventh is a doubled diminished fifth, the minor fifteenth is a doubled minor seventh and the major fifteenth is a doubled major seventh.
All these intervals of two sounds are real chords, consonant or dissonant.
