Description: This study examines the compositional devices Eckhard Kopetzki used to create consonance and dissonance throughout his two works for solo percussion, Topf-Tanz and Canned Heat. By manipulating meter, ostinato, syncopation, polyrhythm, note values and overlapping figures, Kopetzki creates high levels of musical tension and release that shape phrase structure and large-scale form. After a discussion of rhythmic consonance and dissonance, and specific rhythmic devices, both works are considered in detail, illuminating the composer’s compositional language. Topf-Tanz is an exploration of contrasting ideas: the rhythmic and the lyrical, the call and the response, the loud and the soft. It is manifested first in the opposition of antecedent and consequent phrases and second in the overlapping of contrasting metric ideas, which creates prolonged rhythmic dissonance. Canned Heat, on the other hand, is composed through a process of continuing melodic variation. Throughout the piece, melodic motives are prolonged and abridged, creating both delay and acceleration to cadential figures. In contrast to these melodic ideas, each phrase is concluded with stark and syncopated rhythmic punctuations. Topf-Tanz and Canned Heat share Kopetzki’s creation of rhythmic consonance and dissonance. Most notably is the overlapping of contrasting metric ideas between the two hands, and highlighting this contrast ...
