Gaetano Donizetti's Lucrezia Borgia- Com' e bello

The song composed by Donizetti uses several chordophones like what seems to sound like a harp in the background and violins to accompany the woman singing somberly to the audience. You can clearly listen to these instruments accompanying the singer to support the melody, thus making this song homophonic. Of course, the first song played in the following video is pulsatile and has a pretty slow tempo throughout the song to show the character more emotionally struck. At the beginning of the song, her tone is light and brittle, but she then attempts to hits some high pitches here and there. I really did not see any changes in the tempo; just the instruments carry her through the first part of the song. As the song ended, the audience applauded without any restraint and quietly waited for to her to sing again.
There was a nice change from the tempo in the second piece. The piece had a cheery tone and sounded similar as to what you find commonly in most opera music. The song begins with a low, stressed out pitches and then all of the sudden; it becomes an upbeat song that moves the character forward. Finally, the song changes tempo to build up tension for the last few notes and ends it with a loud, booming crescendo.
