Piano Concerto No. 9 in E-flat, K. 271 / Piano Concerto No. 12 in A Major, K. 414

Piano Concerto No. 9 in E-flat, K. 271 / Piano Concerto No. 12 in A major, K. 414 is a pairing of two piano concertos by Wolfgang Amadeus Mozart, composed in 1777 and 1782 respectively. The works exemplify Classical-era clarity and balance with graceful piano writing, elegant orchestral textures and interactive dialogue between soloist and orchestra, and they mark important stages in Mozart's concerto development toward greater virtuosity and expressive depth.
