L'Orfeo toccata & Viderunt omnes Creating a Different Tone

Both pieces are similar in the way that they both add different instrumentation, whether adding female voices or strings, they both use this idea of changing the sound of the piece by adding them.  They are creating a more vast visual by using these techniques.  In the toccata, the wind instruments are already loud, but when the strings are added it softens the sound, making a different painting to imagine, as with omnes, which female voice adds in, giving it this ethereal feel whereas before it sounded like a bunch of serious dudes just sitting around a campfire in Game of Thrones or something just being cool and stuff wailing about God.  When the women join it's like them gathering around a good meal, like rice and vegetable soup, enjoying the beautiful day, saying a little somefin to their Lord and Savior, if you catch me. :-)
