Fiddles go sharp or flat?
Yes, this is a fiddle question on a flute forum, but I know many here play both or know about the fiddle.
Question: does a fiddle tend to go sharp or flat after it's warmed up? Flat perhaps because the strings loosen and create a longer wave.
Helpful info for in session or playing with fiddle if one knows over time if they do go flat while the flute goes sharp as we warm up.
Perhaps the fiddle stays pretty much the same.
Thanks for the info.

Re: Fiddles go sharp or flat?
My subjective experience of being around stringed instruments - fiddles, guitars, bouzoukis, harps, etc...... - is that they tend to go flat as they acclimatise to a warm room, but it may not be consistent across all their strings. Similarly, tune up indoors, go out in the cold to play and they go sharp. However, as they have other parts that can react to ambient environmental conditions, it isn't necessarily so simple - the strings are more quickly affected, but after a while wooden or metal parts will also change. Overall they are probably more stable but less predictable in this regard than flutes and whistles - take us out in the cold to busk and we go way flat, bring us in to a nice warm fuggy sesh and we go sharp. We can warm up the instrument itself at the start of the evening and get it in tune, but as the crush in the room - and the temperatuure and humidity - increase through the evening, we'll find we've gone sharp again and have to tune down. For us it is mostly about the temperature and humidity of the air-column within the instrument, of course, especially once the body of the instrument has acclimatised. Orchestral players have in the past told me that their expectation is for the strings to go out in the opposite direction to the winds if there are environmental fluctuations. Of course, stringed instruments themselves do not get warmed up just by playing in the same way that wind instruments do with our hot, damp breath going through them, but they are affected by, say, travelling in a cold vehicle and then being brought into a warm pub, or coming from a warm Green Room onto a draughty stage.

I respect people's privilege to hold their beliefs, whatever those may be (within reason), but respect the beliefs themselves? You gotta be kidding!

Thanks, Jem, for the detailed response. You're a (shall I say it) gem...sorry, couldn't help myself

Re: Fiddles go sharp or flat?
I'm a reformed orchestral player. Jemtheflute explained it well. Put an in-tune orchestra under warm stage lights and the strings drift flat and the brass and woodwinds go sharp. Sadly, it never quite counters the disastrous tendency of many violin/fiddle players to play sharp to get a "brighter" tone relative to the orchestra.

Re: Fiddles go sharp or flat?
I second Elaine's comment (especially the bright string part)! (and Jem's)
But I think I read recently, here I believe, that strings do the opposite so it is nice to read confirmations of what I believed. Perhaps I should get my wife's cello out and tune it then turn on the heater and see what happens.

Re: Fiddles go sharp or flat?
Years ago I saw John McCutcheon, the great hammered dulcimer player, in a venue where the warm-up room was about 20 degrees different from the performance room, I can't remember whether hotter or colder. Anyway, he came out with his 58-stringed instrument and played one tune. Then re-tuned for about 10 minutes, played another, and so on. I think he spent at least half of the first hour re-tuning. He spent the whole intermission tuning, but with people going in and out, the room cooled off, then during the second set the room itself warmed up by probably 10 degrees from the doors being closed again and all the body heat warming it up. I'm sure it was a disaster for him.jemtheflute wrote:. . .We can warm up the instrument itself at the start of the evening and get it in tune, but as the crush in the room - and the temperatuure and humidity - increase through the evening, we'll find we've gone sharp again and have to tune down. . . .
A good friend of mine, the one who introduced me to Irish music, had a tin ear. And a hammered dulcimer. About once a week for awhile, he'd cook me dinner and I'd tune his dulcimer for him.

Re: Fiddles go sharp or flat?
So if, anecdotally, string instrument go flat when warmed, the next question is ... why?

Clues, schmoos ... Hit me over the head. Jem and Elaine want to do that to me anyway.Denny wrote:already got hints/clues from Jem & Elaine...
Seriously ... metal/wood expansion, air density in the instrument body, speed of sound in the bridge ... what's really going on?

Re: Fiddles go sharp or flat?
The strings warm up and get longer/expand, so they're under less tension, resulting in a lower tuning. Metal(s) expands at another rate as wood, so the effects don't cancel each other out. Actually every kind of metal expands/shrinks at different rates (bimetal cutout!), so the internal structure of wound strings might also change a little.

Re: Fiddles go sharp or flat?
I spent the whole evening tonight playing fiddle next to a brick wall, on the other side of which was the pub's boiler. I was sweating like a sexual professional in a house of worship, and my fiddle was pulling sharp. Cheers,

Re: Fiddles go sharp or flat?
The whacky one is the winds. The speed of sound increases with increasing temperature. As the wind instrument warms, sound travels faster through the warmer air in the instrument. Speed = frequency * wavelength. The speed of sound depends on atmospheric conditions, and the wavelength is set by the shape of the instrument and distance between the toneholes, so the frequency (pitch) increases as the temperature and thus the speed of sound waves traveling through the instrument increases.
This effect overrides even thermal expansion in brass and metal whistles. It does not tend to override thermal expansion of the strings that Gabriel mentioned on stringed instruments.
