Quote from G.P. Telemann (1681-1767)- the most prolific composer of all time:
Fortunately, Telemann seemed to find musical inspiration everywhere, including from the pop and folk music of his day. As he put it, "One would scarcely believe what wonderful ideas pipers and fiddlers have when they improvise while dancers pause for breath. An observer could easily gather enough ideas from them in eight days to last a lifetime!"
"Do not write so that you can be understood, write so that you cannot be misunderstood." -Epictetus
