Program Notes: Clockwork, Op. 34 was written in the spring of 2015 for the percussion trio Tala Rasa. Scored for marimba, vibraphone, glockenspiel and a battery of non-pitched percussion instruments, Clockwork is a six movement work that follows the clock in four hour intervals.  The first movement, ‘From Midnight ‘til 4am,’ opens with marimba and bongo accompaniment in an asymmetric rhythmic groove in 7/8 to drive the momentum to a brief, starry-eyed interlude before the next wave of action culminates into a marimba cadenza and definitive end. 4am through 8am meditates on soft and smooth timbres – bowed vibraphone notes, sparse drums, a floating glockenspiel set on top of a bed of white noise from a suspended cymbal – we are asleep. A thoroughly bohemian lifestyle, from 8am until Noon, one is still deep in dream but slowly beginning to emerge from the nocturnal slumber. A slowly developing rhythmic instability leads to several half-climaxes until our somnambulist is fully awake and beginning their day in Noon Through 4pm. A steady vibraphone pulse is kept throughout with sporadic accentuations that give a sense of instability and propulsion forward to a volatile marimba climax before quickly descending into what can only be an early afternoon siesta, reminiscent of earlier musical material. From 4 in the Afternoon ‘til 8pm develops the primary motive of the cycle with a stable marimba riff accompanying throughout while subversively preparing for the evening to come with a growing rhythmic density, climaxing to the attacca into 8 O’clock ‘til Midnight. An exciting and quickly shifting marimba ostinato, irregular vibraphone accentuations and an unpredictably recurring vibraslap drives our dilettante to the end of their diurnal cycle, reaching a zenith in what can only be described as an absorbing and provocative day.
