A# harmonic base

Harmonic base verification

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

With the A# 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, D# or F, suits you better in the context of the A# drone.

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

Reference loops

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

A# with F

D# with A#

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. A#, your chosen fundamental pitch, may well be the fundamental of your individual tonalities, together with F as quint. However, if verifying your harmonic base you chose D# over F, through the miracle of nature, D# becomes the fundamental of your individual tonalities, and your chosen personal fundamental pitch becomes their quint.
