If you're interested in artistic representations of the four temperaments, you'll find countless paintings, sculptures, allegory plays, and even a ballet. If you want a musical interpretation, I highly recommend Carl Nielsen's Symphony No. 2, Opus 16. Its movements and their respective temperament illustrated are as follows:
2. Allegro comodo e flemmatico (Phlegmatic)
3. Andante malincolico (Melancholic)
4. Allegro sanguineo — Marziale (Sanguine)
This Valentine's Day, have fun listening with your spouse and noticing all of the musical features which best represent your temperaments. Do you hear all of that thunder and lightning in the first movement? Yeah, that would be me.
