The composition of string quartets ran as a continuous thread throughout Louis Spohr’s life, and he used the Quartet No. 10 in A major as his ‘parade horse’, playing it frequently in the Viennese salons to show off his skills both as a violinist and composer to audiences accustomed to Haydn, Mozart and Beethoven. Its first violin part matches the bravura display of the Quatuor brillant No. 3, written as Spohr planned to resume life as a touring virtuoso after resigning from his post in charge of the Frankfurt Opera. The Variations, Op. 6 see the soloist covering a wide range of ideas derived from a theme said to be by Haydn. This is the final volume in the Marco Polo complete Spohr String Quartets edition.
