Capriccio, Op.17

August Gottfried Ritter (25 August 1811 – 26 August 1885) was a German romantic composer and organist.

Co-creator, together with Felix Mendelssohn Bartholdy, of the first example of Romantic Organ Sonata (the first one was composed in 1845); he moved in 1847 from being organist in Merseburg cathedral to become organist in Magdeburg Cathedral. In his critical writings, Ritter condemned the Renaissance organ composers referred to as the "Colorists" for overindulging in ornamentation.
