Based on Jeremiah Clarke s well-known Prince of Denmark s March, Joel Treybig s Prince of Denmark s March Fantasy for two trumpets and organ was composed for the 2015 International Trumpet Guild Conference. Since Clarke s piece was so well-known to the audience, Treybig s piece starts with only a brief quote of Clarke s original setting before quickly moving into newly composed material that features a variety of textures, timbres, and styles, several complete re-harmonizations of the tune, a cadenza for trumpets, and a grand coda that brings this exciting and effective piece to a robust and colorful close.
