Mercury Mercury, The Winged Messenger, written in 1916 is the 3rd movement of Gustav Holsts iconic 7-movement suite. It is light, flitting and scherzando in style. Mr. Sauer has used a very ingenious scoring technique for the brass to keep the music flowing for the very fast, long phrases used by the composer. Instrumentation is for: 4 Trumpets in C (1st part includes Piccolo) 4 Horns 3 Trombones Euphonium (Tenor Tuba), 2 Tubas Timpani and Glockenspiel Mr. Sauer has also transcribed other selections (also available on this site) from Holsts Planets Suite including: Mars, Jupiter, Venus, Saturn and Uranus.
