For the Love of Newton, HOW can guitar strings go sharp?

Question

Other than a change in humidity/tempterature, how in the name of thermodynamics can guitar strings go sharp (i.e. increase their tension)?

Answer 1

Pass an electric current through them then tune the guitar, and THEN stop the current. The atoms slip back into a position of lesser energy and their radii diminish. Over the length of the wire for the guitar string, this overall shrinkage is enough to raise the key to slightly sharp. Additionally, having the guitar close to a radio transmitter will accomplish the same thing, as a current will become induced by the proximity of the radio waves to the metal guitar strings. Again the same atomic scenaroi, as the electrons get less excited when the transmitter is off, the less space the electrons need and slip back into a lower energy level, shrinking the radius of the metal atoms.

Answer 2

well, the fact that after you use the guitar it's tempreture will increase, and to let you know that if the tempreture increases 5 degrees you will notice that the string with the least thickness will affect the most and became several cents flat.
(cents is a term used in tuning meaning one fiftieth of a full note.
Temperature has a great enugh affect on the wood and metal strings of a guitar to change the amount of tension put on the strings.
that's a fact my friend you basicaly can't avoid it.

Answer 3

The same reason other instruments go sharp or flat

Answer 4

actually it depends what kind of guitar and what kind of strings you have....

i have a bc warlock with power slinkies and i can go a whole note higher then the standard eadgbe tune....

Answer 5

the tention like u mentioned
