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.
Simonetta Puccini started in 1980, Simonetta was proven to be Antonio's daughter and was assigned one-third of her grandfather's (now greatly diminished) estate, which included his villa in Torre del Lago, and took his name. The remainder of the estate remained in possession of its original heirs, who were not related to the Puccini family. Another claimed heir, Nadia Manfredi, believed her father Antonio to be Puccini's illegitimate son, but her case was not proven, and was opposed by Simonetta. After taking ownership of the villa, she established a non-profit "Friends of the Homes of Giacomo Puccini" to restore and maintain it.
