This recording was prepared using the Ricordi vocal score published in 2003 and based on the critical edition, with no cuts made anywhere. Note that this edition includes a few minor (and obvious) misprints in Romeo's aria: on page 51, bar 74, the last two notes should be D and E, not E and F, and on page 56, bar 136, the last note of the bar should be a D, not a C (same in the repeat, bar 170).
Where cues are given from Lorenzo's part, I have assumed he is a bass (the 2003 score also includes his part for a tenor).
