D# harmonic base

Harmonic base verification

To verify your harmonic base with D#, your personal fundamental pitch, turn on the D# drone loop. Take a moment to tune in.

With the D# drone running, one at a time and with a moment of listening just to the fundamental drone in between, leisurely try out the two pitches below as many times as you like. Determine which one of the two, G# or A#, suits you better in the context of the D# drone.

By choosing A# over G# or both equally, you verify D#, your personal fundamental pitch, to be the fundamental for your individual tonalities, forming their harmonic base with A# as their quint. But if you clearly chose G# over A#, you can proceed with G# as fundamental for your individual tonalities, forming their harmonic base with D#, your personal fundamental, as their quint.

Reference loops

Turn off any running loop before starting another, or they may sound simultaneously.

D# with A#

G# with D#

Explanation

The harmonic base of a tonality is its fundamental together with its quint (fifth), the first overtone or harmonic that is not an octave of the fundamental. D#, your chosen fundamental pitch, may well be the fundamental of your individual tonalities, together with A# as quint. However, if verifying your harmonic base you chose G# over A#, through the miracle of nature, G# becomes the fundamental of your individual tonalities, and your chosen personal fundamental pitch becomes their quint.
