Liszt: The Grand Sonata

In an article about one of the greatest masterpieces of the 19th century piano literature, Franz Liszt's Sonata in B minor, Patrick Jovell guides us through the history of the work as well as a few of the most common analytical approaches. Listen online to the two recommended performances by Vásáry and Arrau while you follow along in Liszt's autograph manuscript or the printed score available from Piano Street's sheet music library.

hi, i have a key sticking on a baldwin acrosonic spinet.  i can't figure out how to get to the action!  i was able to take the front board off, the board in front of the keys, and the lower portion by the pedals, but how do you actually access the hammers etc?  does anybody know?

if i can access them, i will be able to fix it.
thanks

I have an Acrosonic spinet. Just lift the lid. The hammers are right up on top. Do not remove the action unless you know how. Acrosonic spinets actions have to be tied up a certain way or the stickers (think push rod) will fall out of the holes and you will have a real mess on your hands. I wish I could verbalize it better but I would have to type a book.

When you say sticking, sticking how? Do you think the hammers are rubbing together? Maybe could it be a hammer butt jack is stuck and not moving freely? That being the case the key wouldn't depress. That can be accessed by taking the knee board off underneath. Is the hammer not returning? Might be a spring popped off. You could gently rock the key back and forth, side to side if the key bushing is stuck. Careful, don't crack the key.
There's a lot of things that could get stuck and its difficult to diagnose on the site.
Take the knee board off, get down there with a flashlight and depress the key that is sticking and compare it with the note next to it that is not. You may be able to spot the problem. Or simply lift the lid and see if 2 hammers are stuck together. Common in this crazy weather.

Best of luck.
