With microtonal music the sound of intervals and chords can be more or less dissonant or alien-sounding. Partly this is due to us being used to hearning acoustic music in 12-TET, with timbres that almost without exception share the same harmonic series. The acronym stands for twelve tone equal temperament, where each octave is divided into twelve equal steps. The temperament has has dominated western music for the last hundred years or so. Before that all music was in practice tempered some way, to make chords and intervals more consonant for any given peformance.
Let’s venture deeper into the territory though, and look at the effect the harmonic series has on different tunings and scales. We shall construct a completely novel harmonic series based on the golden ratio instead of the usual integral series. We will also adapt our tuning so that the new timbre can be played consonantly. It will sound like this:
