Turandot Puccini. He left behind 36 pages of sketches on 23 sheets for the end of "Turandot". Some sketches were in the form of "piano-vocal" or "short score," including vocal lines with "two to four staves of accompaniment with occasional notes on orchestration." These sketches supplied music for some, but not all, of the final portion of the libretto. Puccini left instructions that Riccardo Zandonai should finish the opera. Puccini's son Tonio objected, and eventually Franco Alfano was chosen to flesh out the sketches after Vincenzo Tommasini (who had completed Boito's "Nerone" after the composer's death) and Pietro Mascagni were rejected.
Messa (Puccini) in 1878 and was initially conceived by Puccini as a self-contained work. Puccini never published the full manuscript of the "Messa", and although well received at the time, it was not performed again until 1952 (first in Chicago and then in Naples). However, he re-used some of its themes in other works, such as the Agnus Dei in his opera "Manon Lescaut" and the Kyrie in "Edgar". At the end of World War II, Fr. Dante Del Fiorentino purchased an old copy of the manuscript of the Messa from the Vandini family in Lucca, imagining it was the original score.
