The Symphony No. 4 in E minor, Op. 98 by Johannes Brahms is the last of his symphonies. Brahms began working on the piece in Mürzzuschlag, then in the Austro-Hungarian Empire, in 1884, just a year after completing his Symphony No. 3, and completed it in 1885.

The Flute Concerto No. 2 in D Major is an adaptation of the original oboe concerto. Dutch flautist Ferdinand De Jean (1731–1797) commissioned Mozart for four flute quartets and three flute concerti; which Mozart only completed three quartets and only one new flute concerto. Instead of creating a new second concerto, Mozart rearranged the oboe concerto he had written a year earlier as the second flute concerto, although with substantial changes for it to fit with what the composer deemed flute-like. However, De Jean did not pay Mozart for this concerto because it was based on the oboe concerto.
