Specific Impulse
Specific impulse is a term in rocketry relating to engine efficiency. The life-span of a rocket is quite an event, from the highly kinetic launch, to the empty and reflective orbit, to the fiery re-entry. The arched shape of flight is often manifested in music, and in the case of this piece, done so with a hint of programmaticism. Technically demanding, this piece requires great dexterity as well as knowledge of extended techniques on the horn.
