Composer and genre required. One of these pieces by this composer opens with the stormy ascending half notes G, B-flat, C-sharp, and D, followed by dotted figures falling to low D then a dramatic silence. In the Vivace finale of one of these pieces, a drone in the low strings accompanied by gracenotes on the downbeat evokes a Dudelsack used to accompany street performances, giving the piece its nickname. A set of (-5[1])six of these pieces was conducted at their premiere at the Olympic Lodge by Joseph (10[1])Bologne, Chevalier de Saint-Georges, (10[1])and subsequently (10[1])gained nicknames like “The Hen” (-5[2])and “The Bear.” (10[3]-5[1])A set of these (10[1])pieces (10[1]-5[1])named for London (10[3]-5[1])includes (10[1])one (10[2])in which a (10[1])startling (10[3]-5[1])fortissimo (10[1])chord (10[4])interrupts its quiet Andante (10[2])second movement.
