Many Wandelweiser composers feel free to dwell on a sweetly consonant interval or chord.
Next in order of consonance comes the octave (2 1), the interval between c and c′ (encompassing eight notes of the piano keyboard); another highly consonant interval is the fifth (3:2, as from c to g).
Experiment 2 ruled out the possibility that this nonmonotonicity was due to the octave being a more consonant interval than the half-octave, indicating that it represents a true pitch chroma, rather than a consonance, effect.
Consequently, the arithmetic subdivision of the octave can never produce perfectly consonant intervals.
In contrast, humans showed clear preferences for the consonant intervals of Experiment 3 and the white noise of Experiment 4 using the same stimuli and a similar method.
The other three consonant intervals are the fourth (4 3, as C F), the minor sixth (8 5, as C A♭), and the minor third (6:5, as C E♭).
In a duet consisting of eerily consonant intervals, they tell him the story of the man they loved together, Yukihira, who left their village long ago, promising to return.
After so much busywork, Mr. Levingston and Mr. Jacobsen reversed course for an eagerly demanded encore: Arvo Pärt's "Spiegel im Spiegel," a luminous meditation made entirely of lingering notes, consonant intervals and prayer.
His melody lines are characterised as primarily "vertical", employing wide, consonant intervals which express his "extrovert energy and optimism".
The major chords consisted of A, C#, E, A, C#, and as such were characterized mostly by consonant intervals.
The recorded chords satisfy the statistical profile discovered by Krumhansl in classical Western music [30], that is, octave relationships are the most frequently, followed by consonant musical intervals (perfect fifth, perfect fourth) and the smallest probability of occurrence is given to dissonant intervals (minor second, augmented fifth, etc).
