Bianchi had composed the celebrated cavatina 'Semianza amabile del mio bel sole', which Marchesi sung with the most ravishing taste; in one passage he ran up a voletta of semitone octaves, the last of which he gave with such exquisite power and strength, that it was ever after called 'La Bomba di Marchesi!' Immediately after this song, Storace had to sing one, and was determined to bring a bomba into the field also. She attempted it, and executed it, to the admiration and astonishment of the audience, but to the dismay of poor Marchesi.
Bianchi composed the celebrated cavatina 'Semianza amabile del mio bel sole', which Marchesi performed with exceptional taste; in one section he played a voletta of semitone octaves, culminating in an extraordinary note that was dubbed 'La Bomba di Marchesi!' Following this, Storace had to sing another piece and aimed to include a bomba. She attempted it but left Marchesi disheartened.
