Low buzzing noise in high intervals
When playing third or sixths in high shifts on the strings (A and E mostly), there seems to be a low buzzing undertone sometimes that comes with it and is very bothering. Is this phonmenon common?
That buzz is real. It is a difference tone, aka Tartini-tone. It means that those high pitch thirds are in tune. But it is annoying, and composers and arrangers should avoid the high-pitched thirds for the violins. It is not noticed on the piano because the wave-form is percussive, and the piano thirds are not in tune. I don't hear difference tones on the sixths, maybe because my hearing is damaged.
Yes,the Tartini-tone. Congratulations, you are playing in tune! I want a lot of it because it's affirming when I play double stops.
when you hear it and it's bothering you, try tweaking your tuning very slightly. You have to be close to perfectly in tune to hear it at all, but if you absolutely nail the double stop, the tartini tone will usually be harmonious with the pitches you're playing, not clashing or buzzing.
I'm learning a lot on v.com lately. I think I may have produced a Tartini-tone or two. I play more sixths than thirds, and not a lot on higher positions. I think this may be even more noticeable on electric/acoustic violins.
Thet are produced through a form of intermodulation distortion in the ear itself, in a microphone, a preamp or power amp, loudspaeker etc, but not in the air of the room you are in.
