Wolfgang Amadeus Mozart

Organ

A famous Maestro and harpsichord player could not be persuaded that Mozart was as celebrated for improvisation as was said. He challenged him to a public contest and the two professors went to the Chiesa della Passione where there were two organs. Wolfgango Amedeo took the themes which the other professor played on the first organ and improvised on the second in a way that can only be described as divine.
