Orfeo and Euridice: Excerpt from Act II, Scene I by Christoph Willibald Gluck Listening Journal

I am analyzing an Excerpt from Act II, Scene I of Gluck's Orfeo Euridice:
Melody: The melody is mostly conjunct, as it moves fairly stepwise, this seems to be consistent throughout this section of Act II Scene I.
Rhythm: The tempo is more adagio than anything else, as it moves fairly slowly, like it is introducing a new concept.
Pitch: The top part has a fairly wider range, as it goes both in the lower and the upper octave. The pitch for the other instruments stays fairly in a limited range.
Timbre: There is a violin, a cello, and a viola. This could easily be a part for a string quartet, played by the orchestra during this opera. There are only chordophones, and the tone of this piece sounds almost introductory.
Dynamics: The piece starts at a mezzo-forte, and has different dynamics within it. At 0:19, there is a decrescendo and then an accented note several seconds later. There is another decrescendo right before the end of the piece. The volume fluctuates from piano to forte and back throughout 0:53-1:10.
Texture: The piece is homophonic, as there is one distinct melody which is then accompanied in harmony by a few other parts.
