I would like some advice on the various sizes of F-holes on violins. I know there is not a standard size and it seems most Luthiers decide their own, but what is the minimum and average size of f-holes you have encountered?

I get conflicting information and would appreciate som input.

I am trying to determine if a 5/16" (8mm) ball will fit into all violin f-Holes.

 

Thanks

Castle wrote some rules about size and tonal consequences.  But there’s so much fluff, it’s hard to follow what he is saying.  Somebody should synopsize his “rules."

 

Violin tone-peculiarities : Castle, Frederick

 

I think his basic rule is smaller raises tone pitch, larger lowers it.

 

Too bad it's just the opposite. A narrower F hole produces a lower (A0) pitch and a wider one a higher pitch

Hi,

Mass and the structure of wood is the critical factor. Logic would dictate that a bigger hole leaves less mass, therefore favours the higher frequencies. A smaller F hole leaves mor wood and favours the lower ones. However the thickness of the plate, arching and the structure of the wood has to be considered.

Keeping in mind I said "I think... “   :)

 

He says, in fact, “Enlarging exits raises tone pitch.” (p. 51)

 

He discusses the “exits” at length, from page 190 onwards.  Topics include size, obliqueness, and proximity to the edge.

Hi Addie - my thoughts too - so I'm busy trying to work up (down?) an abridged version for my bookshelf.

 

cheers edi

I don't know if anyone else caught this. Anyhow, I just read this in Castle. He says nothing about tone pitch being controlled by the area of the "exits", namely f-holes. He says increasing the area of the f-holes increases the tone-power

One parameter, two effects. Simple, yes? :D

Ha! Right after where I stopped reading last night, I find this morning that Castle goes into great detail about how this phenomenon works. Good catch. I need to finish reading before commenting further and looking stupid.  :lol:

 

'Hook and Link can now have their thread back.

Recently, many scientific papers have suggested "increasing size of f-holes increasing the dB".

Which studies? I remember one in the past which was cited a few times by newspapers. The main effect was an increase of airflow at the f hole edge and nothing more.
