I'm having a bit of a Gothic piano fetish at the moment. I'm currently rebuilding an old piano. A Soviet-era Lirika, only I've had it painted black, sprayed the string frame purple, and my dad sent some candle sconces for the front. I intend to add red leather braiding when I restring it, and possibly re-top the keys with mirrors. It's a long-term project, but if I ever get there, I'm going to need something suitably Alicia Gris to play on it.
I'm fairly adept at tuning a piano, I'm not bad at fixing one, but I'm a pretty poor player. I learned the intro to Corpse Bride a while back and play it whenever we get heavy rains and lightning. It's the only time I take the mute off. I'll never make it to Lucille Sharpe standards, but I do enjoy trying.
I've recently discovered this guy called Lucas King, who does some delightfully Gothic tutorials. They seem deceptively simple, but can be a little tricky. My favourite is called Pain (below), it's satisfyingly funerary. He also does a nice rendition of Dark Fur Elise.
I'm always interested in dark music, so if you've got any other suggestions - and especially stuff that isn't too tricky to play - please do drop them below.
