Symphony No. 4 in A major, Op. 90 ("Italian") and the incidental music to A Midsummer Night's Dream are orchestral works by Felix Mendelssohn, completed in 1833–34 and 1842 respectively. The symphony features bright, rhythmically energetic melodies and sunny orchestration reflecting Mendelssohn's Italian impressions, while the incidental music comprises evocative, theatrical pieces that use lyrical woodwind writing and delicate orchestral colour, placing both works within Mendelssohn's contribution to early Romantic orchestral and stage music.
