Beethoven's Violin sonata no. 4 in A minor, Op. 23 was written and published in 1801, and dedicated to Count Moritz von Fries. It followed by one year the composition on the First Symphony and it was meant to be published alongside the fifth violin sonata, however it was published on different sized paper, so the opus numbers had to be split. Unlike the three first sonatas, this one received a favourable reception from critics. The work takes approximately 19 minutes to perform.
