I don't like this idea of heaven with harps and clouds, though it is a very biblical instrument. David played harp for Saul in the Old Testament and soothed his nerves.

I get happiness from playing solo. It's not impersonal like an orchestra where you might have to count 150 bars of rest. That can be nerve-racking.

Happiness for me is a spiritual thing. I couldn't get it from shopping or eating a few more Jaffa Cakes than usual. A relationship with God is important. I feel unhappy if I'm not speaking to or hearing from him. It's like a marriage. If you don't communicate, it falls apart.

I believe the reason people get unhappy is because they break that connection with God. It's not a fashionable thing these days. I'm not so interested in what's fashionable. I keep Sabbath on a Saturday. I don't work. For me, it's a freedom thing: I get to Friday evening and I can relax. I can be happy. Even if you don't have faith, you need some time out.

Happiness for me is being as peaceful as I can be, which is something I try to pass on to my daughter. The harp has really affected her. I played while I was pregnant and it was a calming sound after she was born. I sang to her. She actually sang back in tune with the notes. She looked at the harp and was transfixed. It looks relaxing, magical, a little like the wing of an angel.
