Classical fan here too. Cannon one of my fav: Pachelbel's Canon in D--Soothing music
Pachelbel’s Canon is beautiful, almost hypnotic in the way it
becomes part of your conciousness.
People hear certain classical passages more often than they may realize.
Another favorite inspiration composition, and extremely common one would be Wagner’s Ride Of The Valkries, when sung by a Mezzo Soprano back by a full orchestra. Now that is both chilling and thrilling.
Her War Cry stays in your head. You can hear it now, can’t you?
