マンハイム楽派
Boury named this piece after the opening gesture of the American Manheim Rocket theme of the finale of Symphony No. 40 in G minor by W. A. Mozart. Although this piece was written for solo piano, there is a full orchestral quality. Like the old composers of the Mannheim school Boury used sudden "crescendo" in the introduction and rising arpeggiated melodic line accompanied by "ostinato". Use of a wide range of keys with chromatic passages and various hairpin dynamic indications support the orchestral quality as well.
