golden1-arp.flac

A timbre (rendered with something akin Paul Naşca’s PADSynth algorithm) which has partials of form m + n ϕ where ϕ is the golden ratio, and m, n are integers. Though not all the partials, just such a set that this all resembles a usual harmonic timbre. This sequence starts

This chord (simultaneous and arpeggiated) is (ϕ + 2) : 3ϕ : (ϕ + 5) : (3ϕ + 3) over the middle C. These kinds of intervals should harmonize well with this kind of timbre by design, though they surely sound unusual and maybe unnatural due to our tendency to evaluate musical sounds as composed of harmonic timbres.
