I'm a beginning Cello player, and I'm usually able to get a clear and consistent tone on all the strings with 1st position fingerings. However today, I've suddenly had bad problems with squeaking.
- Open A and D stings sound fine. A string is completely fine.
- The D string is 100% squeaky with any fingering. It's impossible to get an acceptable sound.
- The G and C strings squeak a little bit open OR fingered.
- It definitely feels like the bow isn't catching the strings enough, but I could be wrong because it catches just fine on open A and D.
Things that have changed between yesterday and today
I lost my old rosin (which was 6 years old but worked fine) and got a new, cheap one (light, soft) as a replacement. I might have used too much rosin trying to break it in, because the lightest bow touch on the string coats the string in rosin, and I've done this 400+ times and it still coats the same amount. I've practically never touched the bow hairs with my fingers, though I did wipe them gently with a clean, dry washcloth after the squeaking, trying to get some of the rosin off (didn't work).
I can't imagine the cheapness of the rosin being the culprit, because the seller is a reputable small business that I deal with a lot and they're trustworthy and wouldn't carry bogus products. Maybe I shouldn't have combined the two types of rosin? Did I use too much? I'm really antsy because I'm afraid I might have ruined the instrument or the bow. What am I doing wrong?
