Light Cycle is a two-movement suite for Intermediate to Advanced Treble ensembles. The suite, commissioned by Jennifer Gaderlund for the Graham Middle School Choirs, sets two beautiful poems by Rhoda Gordon (Light Up and I Celebrate Life), the composer’s late grandmother, for SA (SSA divisi) Choir and Piano.

Light Up is the first movement of the Light Cycle suite. The Piano features a constant rhythmic motor, representing our hopefully constant dancing throughout life. The Sopranos and Altos begin in unison and then break into harmony as the texture unfolds. The middle section contains a round between the Sopranos and Altos, with the Altos offset by two beats. A third (optional) descant part sings above the round between the Sopranos and Altos. The opening material returns with the repeated text “Think light rays” but develops the material further with a few moments of divisi. The piece dramatically builds as the choir repeats the word “glow”, finally resolving with the call to “glow and dance”. The Piano’s rhythmic motor finally comes to a rest at the last measure.

I Celebrate Life is the second and last movement of the Light Cycle suite. The piece opens with an excited yet hushed ostinato in the Piano. The choir sings the first four lines of the poem by repeating the beginning line and adding the next line until it is complete, utilizing the modern technique of additive processes popular in Minimalism. In the more pensive middle section, the ostinato transforms into a more poignant texture as the Choir “realizes the joy of being through seeing the glorious creation” they are a part of. The ostinato then speeds up and returns to the hushed excitement heard in the opening. The piece concludes with the Choir building up to the most important line of the text: “The most powerful light to celebrate by is love.”

Light Cycle is suitable for any Treble-voiced ensemble. The pieces may be may be performed together or as stand-alone pieces. Both pieces explore imitative polyphony and would be a great way for any Treble- voiced ensemble to explore polyphony and part independence. The SSA divisi may be included or omitted as suited to the needs of the ensemble.

Light Cycle will receive its premiere on December 12, 2019 by the Graham Middle School Choirs conducted by Jennifer Gaderlund in Mountain View, CA.
