[Harp-L] What's a "key"?

[sheltraw@xxxxxxxxxxxx]

On another thread the question of how to determine the key of a tune was
raised. So I would like to ask two questions of importance to that thread.

(1) What do you think the term "key" means?

and

(2) Given that you have identified the "key" then what are you going to do
with that information?

Cheers!
