i didn't realize debussy wrote a ballade. thanks for the info! his approach to form is quite interesting. perhaps the ballade gave him as much freedom as a fantasy, but he preferred to let people decide which one it was. am sort of surprised that he didn't come up with his own french term. perhaps they have nothing equivalent (or am i being a little too 'american' in my thought). just joking around, really.
just looked up the term 'ballade' in my Harvard music dictionary and found that Schubert also wrote in this form his 'erlking.' and, liszt and brahms did write ballades, too, as i now recall - so perhaps it was a very standard form. somehow, i had the idea that the impressionists tried to stay away from poetry because it would exactly define the music - but maybe debussy was trying to use a poetic or written form only with music and without any reference to a poet? sort of like writing a ballade with an idea of a story in mind, but no distinct story?
