More days than not, when I get ready to play my uke, and I tune her up, the C string is just a tidbit high. What is going on there? The rest are generally right on the money.
I have played guitar, mandolin and uke for years. If we are at a gig, I tune the instruments serveral times each during the evening. Going sharp is something that seems Sometimes the strings go sharp, sometimes flat. I can't explain why strings go sharp. There is a lot of magic and voodoo involved in it all. Practicing at home I tune my uke several times in an hour.This thread confuses me. I routinely have to tweak a string or two each day. I always have. I never thought a thing about it. I thought that was just a characteristic of stringed instruments. Am I wrong about that?
I have to tune them up once in a while while when I pick it up. But I don't have to tune them up every day. They stay in tune for a long time. In this case though, I wonder why that one string goes sharp? How does that one string get tighter, and whatever is causing it, why doesn't the other strings get tighter? Does that clear up the confusion a little?This thread confuses me. I routinely have to tweak a string or two each day. I always have. I never thought a thing about it.

It has very little to do with the composition of the guitar. Strings stretched across a 2x4 will do the same thing.
The strings warm up when you play them. They EXPAND (get longer -- less tension) as they warm up. ALL STRINGS GO SLIGHTLY FLAT.
THEN YOU TUNE THEM. They are warm from being played. You keep playing and tuning and playing and tuning.
NOW YOU LEAVE YOUR GUITAR THAT YOU TUNED TO ACCOMMODATE THE WARM STRINGS.
WHAT HAPPENS? The strings COOL DOWN (get shorter -- increase tension). As the tension increases the strings GO SHARP.
Wanna test it?
Tune your largest unwound E9 string to straight up on the tuner. Rub the string between your thumb and forefinger the length of the string back and forth 3 or 4 times. Check the tuner. YOU'LL BE SHOCKED
Fascinating ... easily replicable and totally true for long steel strings. I'm not getting such a dramatic variation from short nylon strings, though it certainly possibly helps explain some anomlies I've always experienced with my travel guitar ... low mass, warms up quickly when held close, needs retuning almost constantly for the first few minutes, then it's fine 'till I put it down. An hour later do it all over againHere is one guy's theory from that forum ... Tune your largest unwound E9 string to straight up on the tuner.

I thought it was about second-hand smoke in Colorado.

Maybe the OP's problem is down to the thickness of his C string ... just starting to wonder if this is a soprano we're talking about here or something a little longer?
All interesting stuff
