4. Symphony No. 5 in C minor, Op. 67: Composed between 1804 and 1808, the Fifth Symphony opens with one of the most recognizable motifs in classical music, the famous four-note motif, often described as "fate knocking at the door."
5. Violin Concerto in D major, Op. 61: Completed in 1806, this piece is one of the quintessential works for violin and orchestra, showcasing the instrument's virtuoso capabilities and demonstrating Beethoven's mastery in orchestral writing.
