A 'concertino' for tenor trombone and piano (arguably my first concerto before Requital), Singular Irregularity was my first attempt at a multi-movement work for tenor trombone. This piece came together in chunks and ended up being written backwards (3rd movement first), which explains each movement's stark contrast to the others. The first movement centers around harmony, exploring how a single note can function in different chords. The second movement experiments with rhythm and syncopation through the time signatures of 9/8 and 8/8 (3+3+2). The final movement is a burst of energy that combines the harmonic ideas of the 1st movement with the rhythmic ideas of the 2nd movement. Performance time is roughly 11 minutes.
