JB you just stole my thunder just as I was about to post. My suggestions exactly. The solution is so very simple. just invest in a digital for gods sake then you can cut back your time on the acoustic to one or two hours when the neighbours are out.It aint rocket science.
true it aint rocket science, however we dont' know if debussy is wealthy or??? easy to say "go buy a digital" but we don't know his situation.
It's a safe assumtion that if a family can afford an acoustic piano, a digital isn't unrealistic. Even if you've gotta save up for a month or two, it's not a big hurdle.
