Acoustic Consonance of The Minor Chord
A unique particularity of the minor chord is that this is the only chord of three notes, in which the three notes have one harmonic - hearable and with a not too high row - in common (more or less exactly, depending on the tuning system used) : This harmonic, common to the three notes, is situated 2 octaves above the high note of the chord : This is the harmonic of row 6 of the fundamental of the chord, the one of row 5 of middle note, the one of row 4 of the high note:
- In the example do, mi, sol : a sol, 2 octaves above.
Demonstration :
- Minor third = 6/5 = 12/10
- Major third = 5/4 = 15/12
- So the ratios of Minor chord : 10:12:15
- And the explication of the unique harmonic in common, between the three notes, is verified by : 10*6 = 12*5 = 15*4

Famous quotes containing the words minor and/or chord:
“A child who fears excessive retaliation for even minor offenses will learn very early on that to lie is to protect himself.... If your child intuits that you will react very punitively to his wrongdoing, he may be tempted to lie and may become, as time goes on, a habitual liar.”
—Lawrence Balter (20th century)
“The notes, random
From tuning, wander into the heat
Like a new insect chirping in the scrub,
Untired at noon. A chord gathers and spills....”
—Philip Larkin (1922–1986)
