Plucking or strumming the strings. Recently, I had occasion to hear a woman telling a story whilst she played a sitar. I do believe it was my first live sitar playing story-telling concert like event. In fact, I know it was. Well, not the live women telling stories part, just the sitar part. She told a fascinating tales whilst plinking the strings. Oh, and it was an audience participation type event. Oh. The. Joy. Anyhoo...strings (not necessarily a sitar) or piano playing.
But then again, it really isn't an either / or situation, is it?
Well, in either case, play ON.
