I wrote my TROMBONE in reaction to a composition I composed in 2001 for the Beek en Donk Wind Orchestra, in The Netherlands. Neither melody nor counterpoint were key elements in this earlier piece; and in fact, the musicians in the orchestra commented that they wanted to hear more melody. As a result of their critique, I made it my goal to compose a continuous theme, which I have used in my piece TROMBONE, for l’Orchestre d’Harmonie Nationale des Jeunes. The word “trombone” has two meanings in French. It refers to both the instrument and a small bent wire by which loose sheets of paper may be held together(a paper-clip). These two references are in my composition.
First, I composed several short motives, which were later strung together to form the final melody. Each motif is based on the elliptical form of a paper-clip. Their architecture resembles a nota cambiata or double-neighbour figure, in musical terms. The strict nota cambiata requires a precise interval structure between notes — generally diatonic seconds(major and minor seconds). The intervals in my motives exceed a second for the most part. These larger intervals often suggest two-part polyphony, as we find in Bach’s unaccompanied violoncello suites.
Secondly, I have placed emphasis on the actual instrument, by entitling my composition TROMBONE. The trombone section is given a distinctive role throughout the piece; although it is never treated as a family of solo instruments. The sound of unison trombones is unique. Slight mistuning between players gives it a captivating character. C’est un son extraordinairement riche et trop beau.
There are two other structural elements, in addition to the “paper-clip” motives. The first is an example of plainsong(Gregorian Chant), a response chant taken from the Canonical Hours entitled Media vita in morte sumus. It is used as the bass voice on occasion. The harmonic series is the second element. The series is principally used to create chords over which the melody is played. The work opens with the trombones climbing up the harmonic series, first in F, followed by G and then Bb. The notes of the series are stacked one on top of the other.
TROMBONE provides a good work-out for the brass players. There are significant solos for alto saxophone, english horn and bongos. Rhythmic awareness is a necessity from beginning to end. Drive and momentum are essential.
