If you are looking for some new music to add to your listening repertoire try Brahms Symphony No 4, 2nd movement. It is a great piece!
What to listen for: The piece starts with a distinguished theme in the French horns. Listen then as it moves between different instruments throughout the piece. Brahms not only had different instruments playing the theme throughout but accompanied by different orchestrations as well.
Ready for some relaxing music to unwind to this piece should do the trick.
Try the rest of the fourth symphony’s three movements if you get a chance.
