I'm working on a song, and I can't think what genre to put it into. It is an eerie, echoey song in a major key. It has lots of random sound effects thrown in there, including the backdrop of wind howling. The main instruments are strings, organs, pianos, and synth bells. What genre would this be? Maybe ambient? Experimental? Classical (because it does have a melody, its just very dissonant, echoey, and repetitive)?

I'm thinking Ambient, and if I get no answers, then I'll go with that.
