Women and the Chopin Competition: Breaking Barriers in Classical Music

The piano, a sleek monument of polished wood and ivory keys, holds a curious, often paradoxical, position in music history, especially for women. While offering a crucial outlet for female expression in societies where opportunities were often limited, it also became a stage for complex gender dynamics, sometimes subtle, sometimes stark. From drawing-room whispers in the 19th century to the thunderous applause of today’s concert halls, the story of women and the piano is a narrative woven with threads of remarkable progress and stubbornly persistent challenges.

Mid Part of Piano not WORKING properly after Disassembly

on: October 16, 2021, 03:00:35 PM

Hi, my piano is a yamaha clp 545, and a problem appeared recently which was the loud keys problem.
I decided to disasembly it so i can get to the rubber contact band and clean it.

Behind the keyboard was 3 part of the motherboard, I removed just the middle part because it's where the problem is (c,e and a medium)
when removed the mb i had to unstick the rubber band to it and clean it, so then I put back all the things back together but when played the mid part of the keyboard doesnt work or just work when being hit rly strongly.
I think i didn't put back the rubber back in the goodway, but the direction of it was the right one. so I just need help fix that please

All right, I'm not the best, but I've replaced a few Yamaha actions.

Do you have a picture or something you can upload?

I wouldn't rule out that Yamaha did a factory recall on the action on this one, but I couldn't say without looking at it.

It seems to me that you didn't assemble it correctly. If one side of the rubber doesn't seat properly in place, then only some of the contacts work and that's why only loudest playing makes some sound. Difficult do say definitely from the pictures, but usually the PCB slides under some plastic clips of the case and on the other side it's fixed with screws. The rubber must seat flat on the PCB. If you didn't disassemble the rest of the keyboard you should be able to compare if it's fixed the same way.
