What kinds of things cause a buzzing sound?

If a student approaches me with this, what other difficulties besides these five listed, might be causing the buzzing sound?

1. loose fine tuner

2. too low nut, with the string buzzing against the fingerboard

3. seam that has come unglued

4. crack in the instrument somewhere

5. chin rest rubbing against the tailpiece

These are the things I can think of, out of hand. I also tell them that, aside from making sure it's not a problem with a loose fine tuner, they should have the luthier examine the instrument, as only a luthier can do the repairs.

What else might cause the buzzing sound?

TIA

Some more:

- open seams - (knock all over the instrument over the purfling so see if there is something loose);

- unglued fingerboard,

- loose purfling;

- dirt in the f holes;

- loose soundpost;

- loose collar or pin on decorated pegs;

and many more!!! They can drive you mad!!!

Yes; the "seam that has come unglued" is the one I knew about which I omitted. The others never occurred to me.

The problem with the fine tuners, I have fixed myself more than once, but I'm not sure how to describe it. One of the little metal doughnuts (??) is loose. That I can fix. How would I describe that..?

Sometimes an intermitant buzz can be caused by an object in the room buzzing in sympathy with a certain note. Obviously that is not a problem in itself but sometimes can be mistaken for a buzz in the instrument causing great worry!....Other causes of a buzz that is not the instrument's fault can be the players personal effects, jewelry etc.

hmmm... my favorite instrument smashing topic.

string buzzing flat fingerboard, improperly cut or worn out nut slot, tailpiece buzzing chinrest, usually quiet resident dust bunny protesting living conditions, dead string falling apart, shoulder rest buzzing back of fiddle or having fit problems. buzzing most often accompanied by mental breakdown...

I keep waiting for the other shoe to drop; no jokes about string players "catching a buzz"?

I have the following:

(17) Why is my Viola making a buzzing sound?

A buzzing sound could be caused by any or some of the following:

1. loose fine tuner (loose metal doughnut)

2. lowest point of fine tuner pivot, barely touching top plate

3. string slot on the nut too deep, causing open string(s) to buzz against the fingerboard

4. seam that has come unglued

5. crack in the instrument somewhere

6. chin rest rubbing against the tailpiece or saddle

7. loose chin rest hardware

8. a high spot on the fingerboard

9. unglued fingerboard

10. loose purfling

11. loose lining

12. top and/or bottom block poorly glued

13. dirt in the f holes

14. loose sound post

15. loose collar or pin on decorated pegs

16. misplaced tailpiece

17. gap between bassbar and plate (one has opened up due improper or "sprung" fitting)

18. the bridge protectors are floating on the strings in the afterlength area

19. problem with endpin cork, ring, tip or screw

20. a label on the inside of the instrument can come loose, and buzz at a certain frequency

21. dead string falling apart; loose winding

22. loose string end in the pegbox

23. shoulder rest buzzing back of fiddle

24. loose sliding mute

25. loose wolf eliminator

26. buzz caused by an object in the room buzzing in sympathy with a certain note; sometimes can be mistaken for a buzz in the instrument

27. buzz caused by player's personal effects, jewelry or a button, etc.

28. check the bow; a screw loose on the threaded post can buzz

Aside from making sure it's not a problem with a fine tuner (#1-2), or some problem extraneous to the instrument, (#21-28), you should take it to a luthier and have them examine the instrument, as only a luthier can do the repairs.

Thanks to all!

Here is a short list:

Something nearly and unintentionally touches something..

Most of you likely find what I have found.. Loose glue joints at the plates/ribs seldom buzz.

Off the topic: Isn't it interesting that almost never does a loose edge seem to be pushed against the rib or to pop up? That is in a reasonably shaped arch.

This should say something about the normal component of force or stress in the plate at the edge. At least in the bouts. For those interested in an ideal arching, maybe something can be said.

The grooves are the operative parts of the nut. When we say that the nut is too low, what we really mean is that the bottoms of the grooves are too low.

Did anyone say that the buzzing went away with stopped notes? If the fingerboard doesn't have lumps, discussing the nut should be considered a waste of time.
