| That speech is about the Act II Finale of Marriage of Figaro, which starts as a duet, then trio, then quartet, and finally septet. And it does actually span 89 pages of Act II's 154 pages. But I don't believe it is an applicable precedent for Quintet, One Day More, and the like. In those pieces, everyone sings their individual lines first, and then all are layered over each other. In Figaro, the music that each of the 7 sings when they are all together is new musical material. |
