favorite note and key!

hey guys, just wondering what's everyone favorite note and in what key.

Why I ask? Simply to find more cool sounds on the harp I might have missed.

Personally I absolutely LOVE octaves, specifically hole 1 and 4 on my g harp. It sends shivers down my spine hahaha. I try to sneak it into almost everything I play that I think will sound cool with it. Add a tremolo to that baby and it's pure cotton candy for the ears!

looking forward to hearing about your favorites boiz or gurlz.
