45.B.1
I-Li
Istituto Musicale "Luigi Boccherini", Lucca
First part of a double leaf, 4° oblong format (33 × 24 cm) with 12 staves.
42 bars (= first part of 45.B.2).
Notated in the soprano, alto, tenor, and bass clefs.
46.B.1 is written on the second part of the double leaf.
In the margin, Puccini wrote the words: “Alcune Fughe a 4” (probably added sometime after the work had been composed).
45.B.2
I-Li
Istituto Musicale "Luigi Boccherini", Lucca
1 double leaf, 4° oblong format (33 × 24 cm) with 12 staves, a total of 85 bars, and a few corrections in another hand.
Notated in the soprano, alto, tenor, and bass clefs.
This is probably a copy of 45.B.1 and its continuation to the end, which Puccini may have considered unsuccessful in the (lost?) second part of 45.B.1.
