I played at the very same castle in the trailer on 6th August - Hedingham Castle in Suffolk.
Probably my favourite venue so far - fantastic acoustics, incredible atmosphere....the only bad thing from a harpist's point of view, and it was a pretty big one, was the stairs situation. Fortunately I had been forewarned by my harp teacher (yes, even at the grand old age of 32 I still have a teacher!), and took my star of a Dad with me. Dad was a complete hero and helped me all the way up the wobbly steps.
and then up the spiral staircase....
then up some more nice shiny wooden steps....
to about half way up the keep, where the double windows are.
The photo in my profile picture was taken in the Banqueting Hall. It was worth all the effort, and my dad, who was listening out of sight in the basement, said the acoustics were such that he could hear every note. Congratulations to the bride and groom!
