This dissertation provides insight into the compositional characteristics of Paul Lansky's instrumental works as demonstrated in Hop (1993). As well, this document intends to make Hop more approachable to performers through a structural, harmonic, and rhythmic analysis. This dissertation presents a brief overview of Lansky's biographical information, discusses background information about Marimolin (the ensemble that premiered the piece), and provides an analysis of Hop. Hop is analyzed with regard to form, harmony, and rhythm. The analysis was conducted through a tonal approach, and harmonies are identified with a lead sheet analysis. Personal interviews with Paul Lansky and marimbist Nancy Zeltsman provided significant insight into Lansky's influences, musical characteristics, as well as other elements pertaining to Hop.
