Thanks everyone…and thank you Sylvia for sharing your tips. I’m not used to improvising and playing by reading chord symbols (i.e. when they are not explicitly written out). I guess it’s a skill you have to learn…I’ve always admired people who can improvise on music on the spot.
The problem with being an amateur, I guess, is when you said you won’t do it, people will take it as your incompetence. While if you’re a professional, they would take it more seriously and think that perhaps their demand is unreasonable.
Philippa, I’m sure they have some very good pianists too…but for some reason the conductor wanted the harp to play, since it sounds “pretty”…but then of course they’re forgetting (or not aware) of the fact that the harp will never sound as loud as the piano so they can hardly hear it.
