This is great. Your speed and inflection when speaking are just right, your explanation was just what I needed, and the angles were informative. Thank you!

In my piano one of the Key doesnt touch the string. In fact the hammer barely comes up from its rested position. What I noticed is that when I Open the keyboard, PUSH UP the bottom tip of jack with my finger and then press the key, it plays the key for one time. As soon as I release the key it again stops working. Also when looking at the jack from the front of the keyboard, It feels like this key has a jack which is slightly lowered compared to all its adjacent keys. What should I do. Thanks for your help.

So then what do you find more efficient since you close by saying "you find it not efficient"?

I have some keys on my Schimmel that don't sound, I think this is the issue. A tech wants $650 to do regulation and I dont have the doe, so I'll try this
