The archaeotonic scale is overall brighter, more "majory" and more concordant than the oneirotonic scale: there are more 4:5:9 chords and chords involving the 11th and 13th harmonics, and extremely dissonant intervals such as 16/11 and 32/21 are less common. | The archaeotonic scale is overall brighter, more "majory" and more concordant than the oneirotonic scale: there are more 4:5:9 chords and chords involving the 11th and 13th harmonics, and extremely dissonant intervals such as 16/11 and 32/21 are less common. | ||
An interesting feature is that you can switch whether you perceive an interval as minor or major by approaching it from opposite directions: for example, a minor sixth can be made to sound like a diatonic major sixth by walking up large-large-small-large-large from the tonic or like a diatonic minor sixth by walking down by two whole steps. | The unison to octave interval categories remain exactly the same as in the diatonic scale, except that there are now major fourths (6\13, approx. 11/8) and minor fourths (5\13, approx. 21/16) An interesting feature is that you can switch whether you perceive an interval as minor or major by approaching it from opposite directions: for example, a minor sixth can be made to sound like a diatonic major sixth by walking up large-large-small-large-large from the tonic or like a diatonic minor sixth by walking down by two whole steps. | ||
