Chinrest weight and sound
I just want to share... I was using a custom made, pure ebony chinrest. I was very proud and it looked great. However, while trying some alternative shapes I started to notice changes in the sound... I have been experimenting and there is a clear and provable inverse relation between the weight of the chinrest and both the volume of sound and the clarity.
I could not find such obvious change in the chinrest position once you adapt your bowing.
But the weight difference is very noticeable. By myself, by listeners and by sound apps.
I see it has been mentioned before, so just a +1 to that fact and another tool if anyone wants to change the loudness of the instrument.
I have also noticed the relationship between chinrest weight and sound.
I suspect it is not only the weight of the chinrest that is significant but also the contact area of the cork with the violin. Accordingly, I like to minimize that contact area by cutting away the cork in various places so as to allow more vibration of the body. This is probably best done when the cork on a well-used chinrest is starting to deteriorate and it is time to re-cork.
Yes, the chinrest definitely changes the sound coming off of the instrument. And, to an even larger degree, it changes the players perception of the sound.
Question — is there a difference between playing with your custom made chin rest and without a chin rest? Would it be louder without the chin rest?
What is happening is that when you try a different chin rest your ear moves relative to your f-holes and your violin sounds different.
I have just a few anecdotal data points on this, but I've noticed the chinrest mounting can affect how much the chinrest affects the sound of the violin.
Re Paul: the OP mentions "by listeners and by sound apps", so it doesn't seem to be just the ears of the player.
Sound is certainly one thing which is at least noticeable, but I simply like the handling of violins with heavy chin rests very much (low center of mass, etc.).
Carlos, once you have tried your experiment on enough fiddles, I think you'll conclude that "it depends on the fiddle", and also that it is highly dependent on the personal tastes of the players and listners.
I noticed this also and I have since discarded my ebony rests and replaced with one made from light weight wood. I also cut excess wood from the replaced rest thus weighing even lighter.
At all: Regardless of the quality of the sound produced, which is a subjective point, a phone in the music stand measuring the sound was showing consistenly 2-3 db louder with no (or light) chinrest.
