Textural Cluster Pedal

This piece starts with a textural cluster pedal in the low strings, using the notes D and F played simultaneously. They are repeated as 16th notes at 135 BPM in 4/4, creating a measured tremolo. Technically, a cluster involves three or more adjacent notes, often a group of semitones. In this case, the D–F minor third functions similarly by adding harmonic tension and a dense texture. This dyad acts as a pedal point, supporting the harmonic foundation without changing pitch. Meanwhile, the piano carries the melody, providing contrast through a more expressive, fluid line.
