Quadrangularis Reversum

Quadrangularis Reversum is a piece inspired by Harry Partch’s marimba-like instrument of the same name which is a real-time interactive duet between a solo violist and six unique FM synthesis sounds crafted in Max/MSP. The ratios available on Partch’s instrument, situated so that the player can easily play them in sweeping arpeggios, are here rendered as frequencies in the free just-intonation program Scala and stored as a list in a coll object in Max. The chords are first tuned to the C subharmonic series, and then to the F harmonic series. After a meditative introduction, the Viola player chooses to play various notated figures in a semi-random order they wish, triggering different “chords” from the C subharmonic series in Max, each one related to the original arpeggios found on Partch’s instrument. These choices are stored as an independent list and are recalled by Max to trigger the same “chords” retuned to fit into the F harmonic series when the violist exists the stage, and the material which was layered in the beginning returns as if a phantom version of itself. Thus the subtitle What’s Inside the Mirror relates first to the form of the piece, as well as to Partch’s construction of the Quadrangularis which was itself a mirrored version of an older instrument he designed called the Diamond Marimba. It is a mystical piece, which hopes to find the listener reflecting on the present moment, the eternal now – to find a quiet moment with themselves outside of the mad rush of the human world. Quadrangularis was premiered at my senior recital at University of the Pacific on November 28th 2018.
