Ludwig van Beethoven's Piano Concerto in E flat major, WoO. 4, is one of his earlier works, written in 1784 when he was only 14. Only the solo piano part survives today, although there are some indications in the manuscript for orchestral cues. On the occasions when the work has been performed, the orchestral part has had to be arranged beforehand. The concerto is sometimes referred to as Piano Concerto No. 0, as it came before all of Beethoven's other piano concertos. It is rarely performed. Pianists Howard Shelley, Ronald Brautigam and Philippos Tsalachouris, as well as the Swiss musicologist and composer Willy Hess, have each made their own reconstructions of the concerto.
