written for and performed by Hypercube (Chris Graham, Andrea Lodge, Erin Rogers, Jay Sorce)

Throughout the composition, the musicians are presented with multiple staves.  They are allowed to choose and play from any of them, and can switch between staves at any time (barring a few rules).  The piece is meant to be a game for the ensemble, constructed as a "choose-your-own-adventure."

About “Ad Parnassum” (Ad Parnassum, 1932)
The dark outline of a pyramid-shaped mountain glows beneath a warm orange sun while an open archway invites the viewer to take the first step on their journey towards enlightenment. Inspired by the pyramids and temples of Egypt, Paul Klee’s pointillistic masterpiece from 1932 is built from contrasting blocks of color built up brick by brick in a style that he called “divisionism.” In the same way, the music takes the form of a rondeau as repeated musical progressions are developed through textural variations. In Greek mythology, Mount Parnassus is associated with Orpheus and the home of the nine muses and “a step towards Parnassus” (gradus ad Parnassum) came to define the gradual process of pursuing mastery in scholarship or the arts through diligent, repeated practice. The climb towards any summit begins with a single step and although that journey can be defined as a series of steps towards a goal, there is no guarantee that the path will be straightforward. The path may be winding, or may double back on itself, or seem to disappear altogether – it is built from small victories, epiphanies, frustrations and defeats – and by the end you have come full circle, stepping through the door towards Parnassus once again, both an exit and an entrance.

In "Short Tempered", the performer reads a one-page score top to bottom with the accompanying electronic track in MaxMSP, then flips the page upside-down and reads a "reversed" version of the music with the electronics also reversed. This piece was commissioned and premiered by yours truly in 2016.

Associated Text:
Whispering pinks tell me my
streetlights are lightyears away and
their horizon hugs a new sky that I can’t see except
only in the detail.
And my streetlights glow from
lightyears away
and they show me a new sky
that I can’t see except
only in the detail.
Whispering greens tell me my
place is at once here and not here
- the silence breathes -
and you help me find Hercules

pallid amethyst
catching embered sapphires
surged golds
the boldest of them
a ruby supreme
sundered opals
atop ashen grounds ushered
by unnatural natural
- the music hums -
and you say my eyes like it too

Sun Songs - I. passenger

play a vibration in the rhythm of the universe 
 play a vibration in the rhythm of dreaming 

 play a vibration in the rhythm of dreaming and slowly transform it
into the rhythm of the universe

repeat this as often as you can
