Concertos pour piano No. 20 en ré mineur, K.466 / No. 23 en la majeur, K.488

Concertos pour piano No. 20 en ré mineur, K.466 and No. 23 en la majeur, K.488 are two piano concertos by Wolfgang Amadeus Mozart, composed in 1785 and 1786. They exemplify Mozart's mature Classical-era concerto style, featuring a balance of lyrical melodies and virtuosic solo writing set against Classical orchestral textures, and they originate from his productive mid-1780s period when he was refining the dialogue between soloist and orchestra.
