Amadeus is a play by Peter Shaffer which gives a fictional account of the lives of composers Wolfgang Amadeus Mozart and Antonio Salieri, first performed in 1979. In the words of Playbill: 

It’s 1823, and a cacophony of scandalous whispers echo through the streets of Vienna. Renowned Italian composer Antonio Salieri flees from claims of murder but has nowhere to hide. While chasing fame and fortune, we learn how Salieri becomes obsessed with the rowdy young prodigy, Wolfgang Amadeus Mozart. A deadly game of envy, deceit, and revenge ensues. Who will prevail? The villainous veteran or the worshipped wunderkind? Musical history is enlivened and re-imagined in Peter Shaffer’s award-winning parable about malice, madness, and the love of music.
