Here you’ll find a video capturing another improvised piece of music of mine which I named A Guiding Light. A guiding light can be metaphorical for a person who offers support, perspective and clarity; or for our own inner compass, intuition, and hope; enabling us to navigate uncertainties, challenges and darkness. For me, these ideas were represented by the warmth, light and groundedness of A major (A Ionian mode); and the twilight, shadows, ambiguity and mystery in the A Mixolydian flat 6 mode and F harmonic minor.
In this improvisation I used the A Mixolydian ♭6 mode to bridge the gap between the warm, stable, and bright A major (Ionian mode) and the darker and more haunted F harmonic minor. The A Mixolydian ♭6 mode keeps the lifted major 3rd degree (and the same major quality tonic triad) of A major/Ionian, but flattens the 6th and 7th degrees (resulting in a minor 6th and 7th), thus introducing shadow and a hint of minor sound, creating the distinct hybrid major/minor twilight sound of the Mixolydian ♭6 mode. This creates a kind of liminal space, before descending fully into the minor darkness of F harmonic minor.
I returned to A major for the final section, and this modulation was more abrupt than the previous ones, like a path that was previously overlooked suddenly coming to light after we fear we’ve lost our way. This return to the tonic key created a kind of structural resolution, like navigating the way back home after a journey through shadows and secrets.
