About
An sound agglomerate is a cluster of pitches defined by intervallic relationships rather than functional harmonic identity. This tool allows you to explore the 95 valid sound agglomerates and hear how they interact with different bass configurations.
Constraints: Four notes, within one octave (span < 12 semitones), no uniform tertian stacking.
Intervals: S = semitone (1), T = tone (2), m3 = minor third (3), M3 = major third (4), 4 = perfect fourth (5).
