Plateau Clarinets: A plateau clarinet simply does not have holes for the fingers to close, they have covered keys. They are great for young students that have trouble covering the holes and for players of any age that have trouble covering the holes. They sound just like a regular clarinet.
Low C Key Bounce:
On many saxophones the G-Sharp and Low C keys tend to bounce. The reason for this many times is the spring placement. The spring is right near the rod of the key and this allows the key to bounce unless it has a lot of tension on the spring. Not enjoyable to play with this tension.
This photo shows the traditional placement for the Low C spring.
By making a slight grove further out on the key the bounce can be made less and still have a spring tension that is usable. It does not weaken the key and allows the response time of the Low C key to be improved. I also used a stainless steel spring to help with the bounce because they tend to bounce less.
This photo shows the spring placement.
Very easy fix……
Common clarinet repair mistakes: Article No. 1
One of the most common mistakes made by many repairmen is they use a pad that is too large for the 1st finger left hand key under the throat A key. This is the tone hole that allows the open G to speak and if the pad is too large the throat G will be stuffy. This pad should be just big enough to cover the tone hole and not hang over the pad cup.
This is likely the only key you would like the pad and pad cup to be the same size.
The J. L Smith Valentino Master Series Pad – Tan/Cork – .110” pad is great for this key. It is smooth and there is not fish skin to start to make the note stuffy.
