String tension pitch

[pfchang]

So i've started being more conscious of my stringing, and one thing i noticed the other day when i was stringing was that after i had finished all of the mains, the pitch of the string was lowest around the middle, higher and even around the last couple of mains toward the outside. Is this supposed to be normal?

I also acquired an e stringer, transitioning from a dropweight, but i just can't help but be paranoid about the actual tension. The tension callibrator is all over the place sometimes. Strung a APD at 53-54 and ended up dropping straight to 47.5 after i took it off the machine according to racquettune.

Just want to make sure im doing things right.

Yes that is normal. As you keep string toward the outside mains the racket collapses and he center mains are looser. As you string the crosses the racket is stretched back out and it should be normal length when you finish.

Resonant frequency is function of tension, resilience & length.

So even if string is same tension, shorter string will sing at different pitch.

this is the answer.

Mount the racket and measure the racket length. String the mains only and measure the length of the racket. They will not be equal.

Irvin may be a little right but Tamiya has the mostly right answer. That's how guitar frets work, y'know, shorten the string, higher pitch.

Thanks all, sad to see my education in physics has gotten me nowhere Ha.

this is likely true, but it's not the answer to the question about shorter strings at the same tension being higher pitched.

as stated above, ever played a guitar?

The center strings wil not only be longer causing a lower pitch, but the will have less tension (because of racket compression) which causes a lower pitch. Ever turn the tuning key on a guitar? One way increases tension and pitch and the other way decreases tension and pitch.

EDIT: I am assuming the OP is questioning the pitch of the center strings after all main are tensioned as compared to when just the center mains are tensioned. True a shorter string will produce a higher pitch sound without question that is why effectively shortening the length of the guitar string with a fret produces a higher pitch. If you tighten the string you will also run the risk of breaking the string. Also lengthening the string produces a lower pitch and is the reason bass instruments have longer string. If you lower the tension on the bass instrument you will also get a lower pitch but you will not have as loud a sound. The instrument will also be dead.

lastly, thicker strings produce a lower pitch than thinner strings.

I would hope hoop doesn't crush down noticeably much,
otherwise IMHO your machine's 12 & 6 frame clamps aren't tight enough.

I like strumming the mains before starting crosses.
The 7/8/9-note minor chord is good way of making sure nothing's slipped,
especially when cranking 4 sticks @ 4am last night.

Not really noticeable but it is measureable.

Don't forget the flatted diminished 5th.

 

[Tamiya]

I hear that with power pads...

Or the Add 9...
