Original: Like '' Tortues , '' this is also a musical joke - the thematic material is taken from the Scherzo from Mendelssohn 's incidental music to A Midsummer Night 's Dream and Berlioz 's '' Dance of the Sylphs '' from The Damnation of Faust .
Simplified: This is also a musical joke - the tune is taken from Felix Mendelssohns Incidental Music to A Midsummer Nights Dream and Hector Berliozs Dance of the Sylphs where it is played on high-sounding instruments .
