First composed in 1809 as a viola showpiece for his for his step-brother Fritz, Weber's Andante et rondo ongarese remained unpublished in the composer's original settng for decades after the composer's death. In the wake of the touring composer's great success with his Clarinet Concertino of 1811 - composed for Heinrich Baermann, virtuoso clarinetist of the Munich Court Orchestra sortly after the composer's arrival there, the orchestra's bassoonist Georg Friedrich Brandt demanded a concerto for bassoon, which was premiered later the same year - again to great acclaim. In 1813 Brandt asked Weber for another bassoon concerto, so the composer reworked his earlier viola showpiece into the one for bassoon and orchestra which is the version ultimately published and generally known today. This newly engraved edition by Richard W. Sargeant, Jr. corrects the numerous mistakes that are in the parts and presents for the first time a published orchestral score using both the manuscript and the original parts as sources.
