Vivace (2010) for string orchestra began its musical life as the third movement of my Sonata for Guitar (2009), recorded by Isaac Bustos on MSR Classics [MS 1581]. While writing the sonata I began to realize what a symphonic instrument the guitar really is, and how well idiomatic guitar figurations might translate to the orchestra. As the title suggests, Vivace is a short lively piece tinged with spiritual uplift. Supported by a steady rhythmic ostinato in stretto, the broad melody (in slow harmonic rhythm) is presented first in the highest voice and then answered in a lower one. The dovetailing of gestures and its consequent antiphonal character permeate the movement. Often the melody is presented in harmony at the interval of the 7th or 9th. As with many of my recent compositions, variation, color and drama are enhanced by the juxtaposition of pandiatonic passages with those that are chromatic and dissonant. --Peter Lieuwen Vivace has been recorded by the Slovak National Symphony Orchestra on MSR Classics [MS 1582].
