Mozart, Sonatas in E minor K304 for Violin and Piano ( Henle)

Mozart's "Romantic Sonatas" for violin and piano have uncertain authorship. The original autographs are missing, and the publisher, Breitkopf & Härtel, doubted their authenticity. Konstanze, Mozart's wife, offered the sonatas to the publisher in 1799, but they were disappointed and requested the original manuscript. However, it could not be found, adding to Konstanze's doubts.

Mozart's Sinfonia Concertante for Violin, Viola, and Orchestra in E-flat major, K. 364 (320d), was composed in 1779 during his tour of Europe. This piece is a cross-over of symphony and concerto and showcases Mozart's exceptional musical talent. The piece's three movements are filled with intricate melodies, harmonies, and rhythms that demonstrate the complexity and depth of the composition. Its average performance time is half an hour.
