Piano concerto
A piano concerto is a concerto written for piano and orchestra.
Characteristics
Form
A classical piano concerto is often in three movements.
A quick opening movement in sonata form including a cadenza (which may be improvised by the soloist).
A slow, free expressive movement
A faster rondo
Examples by Mozart and Beethoven follow this model, but there are many others which do not. Beethoven's fourth piano concerto includes a last-movement cadenza, and many composers have made innovations - for example Liszt's single-movement concerti.
