The Adagio is based on a manuscript that was discovered in the Dresden State Library after the Second World War by Remo Giazotto, a Milanese musicologist who was working on Albinoni's biography at the time. Only the bass line and six bars of melody were found and they probably belonged to the slow movement of a Trio Sonata. In 1945 Giazotti reconstructed the now famous Adagio which has made Albinoni known to a worldwide audience.
