Beethoven’s friend Louis Spohr was one of the most significant symphonists of his day and his nine works in the genre divide fairly evenly into those which follow classical traditions and four which have titles. Symphony No. 4 in F major, Op. 86 is subtitled Die Weihe der Töne (The Consecration of Sound) and is a programmatic work, based on an eponymous poem by Carl Pfeiffer, that offers both a novel symphonic form and a powerful musical narrative. Spohr was also a hugely influential figure in the development of German opera, as the two overtures clearly demonstrate.
