 Edward Elgar attempts to use the timpani to imitate the engine of an ocean liner in his "Enigma" Variations by requesting the timpanist play a soft roll with snare drum sticks.However, snare drum sticks tend to produce too loud a sound, and since this work's premiere, the passage has been performed by striking with coins.Benjamin Britten asks for the timpanist to use drumsticks in his "War Requiem" to evoke the sound of a field drum.
