Ok, let's have an initial try.
1. Liszt - Mephisto Waltz, Totentanz, I'm sure there are other possible connections.
5. Tausig - Das Geisterschiff (not as hard as it sounds, incidentally)
Two points for you! For Liszt I actually thinking of a more obscure piece called "Trauervorspiel und Trauermarsch".
I looked at the score to Das Geisterschiff-- it LOOKS scary!!
I'll take the easy one. Mussorgsky, Night on Bald Mountain.
(Someone knows Taussig by sight??)
One point for you! (I wouldn't know Tausig by sight, either...)
Mad Dowell Witches Dance
Saint-Saens Dance Macabre
Tchaikovsky Hamlet ???
I had to use Google image search to find Tausig... the image did not ring a bell.
Two and half points for you! Is MacDowell really mad? haha. He also wrote a piece called "A Haunted House". I'm going to check it out. Maybe I could get it learned by Oct. 31. Half a point for Tchaikovsky because you had the name right, but I was thinking about a piece he wrote called "The Witch" or "Baba Yaga".
