Both of these quartets are transcriptions of quintets for winds and piano by their respective composers but the links that bind them go much deeper. In the year after Mozart's death, Beethoven began the draft of a work for the unusual instrumental ensemble of four wind instruments and piano. He was inspired by the similar work by Mozart, which had largely emancipated winds from their role in Harmoniemusik, employing them instead in the sophisticated ambience of chamber music. In this performance, following Beethoven's own practice, the cadenzas in his quartet are improvised.
