In the 1830s, Louis Spohr was commonly considered undisputedly the greatest living composer. He was inspired to write his four clarinet concertos, which have always ranked among Spohr’s most popular works, by his acquaintance with the Thuringian clarinetist Johann Simon Hermstedt. Up to today, the decidedly virtuoso clarinet concertos have been a challenge for any clarinet soloist, as they mirror Spohr’s view of the form of the solo concerto as a projection surface to flaunt technical skill in an ideal symbiosis with the poetic and lyrical contents of the music.
