Hummel’s affinity with Mozart’s musical language began in 1786, when the very young Johann Nepomuk lodged with the Mozart family in their home for two years. • Hummel’s interest in, and knowledge of his teacher’s works for fortepiano and orchestra is attested by many accounts. • This recognized authority, added to the widespread approval he enjoyed as a composer, created the context in which Hummel produced his numerous transcriptions (approx. 50), scored principally for flute, violin, cello and fortepiano, applying now-historically valuable improvisatory practice solutions as well.
