Iridescence (progressive rock instrumental)

It's been too long!

I thought I would share this piece written for my theory and composition class at Berklee. We were asked to work with a couple of "exotic scales" from a selection including the whole-tone scale, the octatonic scale, and modes other than those derived from the major scale. I felt drawn to the Lydian Augmented and Spanish Phrygian modes. I ended up with a contrapuntal rock instrumental in rough ABCA' form. 

The A section is in B♭ Lydian Augmented, the B section is in G Spanish Phrygian, and the C section an unbroken transition into D Spanish Phrygian. Finally, I modulate with the common tones D and A back to B♭ Lydian Augmented, for the A' recapitulation.

The title (Iridescence) was inspired by my understanding of modes as a concept. With many modes sharing the same collection of notes, the tonic note that each mode centers on is what makes it unique -- gives it a unique color. And, iridescence is when something appears in different colors depending on the angle of viewing. I see that as a fitting metaphor.

The artwork is my own, made with ProCreate. I didn't paint it for this track, but as a birthday present for my mother, inspired by Kate Bush's song "Kite". She is a massive fan of Kate's and introduced me to her when I was a little girl. I rediscovered her recently and I've been spending a lot of time with her early work. My current favorite album is Never for Ever...whose influence I thought was bleeding into this track. So, in the end there is some relation. 🙂

I hope you enjoy! Any feedback on both the mix and composition is more than welcome.

P.S. I was required to include a detailed score for the assignment. It might be too precise for a rock track in general, but if enough people are interested I will upload that, too.
