I am new to the cello and have been experiencing a sound on the G string that I can't quite pinpoint the cause of. Everywhere I have looked online appears to be specific to wolf tones or rattles, and I don't believe it is either.
The best I can describe the sound is like a metallic tone on top of the normal G frequency. I only get the sound when I play open G and it is not every time, sometimes it takes some effort to replicate. Here are a few other observations I have made:
- No other strings are contributing. I can dampen all other strings and it still makes the sound.
- It seems to get worse with more rosin.
- There doesn't appear to be anything else on the cello vibrating.
If I can't figure it out, I plan to take it to the shop where I bought it to see if they can troubleshoot, but I thought I would ask here first just in case it is a possible easy fix.
The cello is an Avalor Studio 2008 - Guy Cole with Thomastik Infield Spirocore G and C strings.
Edit---- Audio clip is here: https://voca.ro/bLownwgbPX0 The second bow stroke has the sound in question.
Thanks in advance!
