Clarinet Concerto No. 2 Op.74 in Eb Major 3rd Movement by Carl Maria von Weber composed in 1811. Like all of Weber's clarinet works except for the Grand Duo Concertant, it is dedicated to Heinrich Baermann, who was soloist at the premiere.
Considered staple clarinet repertoire, the 3rd movement in E-flat major is an exhibition of technique and style on the part of the soloist. The polonaise is a slow ballroom dance, yet some soloists choose to take the movement at a far faster speed than what is traditional or intended for the true polonaise dance; nonetheless, many soloists dedicated to the text choose to take the movement at the danceable speed of a traditional polonaise.
