WEBER Carl Maria Von, Grand Duo Concertant in E flat Op.48

Allegro con fuoco 
Andante con moto 
Rondo. Allegro 

Weber’s own diaries contain a wealth of information about when he composed this work. The first movement to be written was the Rondo finale, completed in Munich on 5 July 1815 and a note from a few days later mentions sketches “for the sonata with clarinet and piano”. By 19 July Weber had also written the slow movement, describing it as an “Adagio”. It wasn’t for another year that he turned his attention to the first movement – noting in Berlin on 5 November that the “First movement of the Duo in E flat was written down”, and finally on 8 November “Allegro in E flat for the Clarinet and Piano Duo finished.” The work was published by Schlesinger in Berlin six months later, Weber noting that he received printed copies on 19 June 1817.  


What is remarkable about this work, given its rather fragmented composition history, is that the finished piece has such concentration and coherence. An early review in the Allgemeine Musik-Zeitung was full of praise: “The whole piece has an original and fiery spirit as well as tender heartfelt feelings; a thorough development of ideas comes without any pedantry … The harmonic and melodic aspects of each movement are beautifully balanced against each other and both instruments are treated with a perfect knowledge of what each can do.” 


The ebullient and virtuoso writing for the two instruments in is one of the glories of the Grand Duo. It was conceived as a real partnership for clarinet and piano, with neither part dominating the proceedings. The results are very rich melodically but also extremely successful in terms of Weber’s handling of large-scale forms. Though the work was called Grand Duo concertant when it was published, it’s interesting to note from Weber’s diaries that he referred to this substantial three-movement work at least once as a “Sonata”.
