Uh, why don't you try a bit of metal? You know, there are those power, symphonic, melodic metal bands... They are great, write about geeky stuff (like dragons, epic battles, unicorns, whatever), and have some really smooth piano sounds! Check those out:
Shaman - Fairytale
Nightwish - Last Ride Of The Day
Tarja - I Walk Alone
Avantasia - Dying For An Angel
EdGuy - For All The Clowns
