take off all the old ones and than put new ones on, you may have to adjust the action and neck on the guitar depending on how drastic the string gauge swap is.
but 90% of the time I find you dont have to do anything but change the action.
the frets make the guitar string make a different sound.
The sound is produced by the vibration of the string.
It causes the string to vibrate more slowly, decreasing the pitch (frequency).
depending on the the individual gauges of the six (6) guitar strings ie: E, A, D, G, B, E, of course the guitar string that is long and loose produces the lowest pitch... A good example of this are the strings on a mandolin or a 'banduria' which has shorter strings compared to the strings on the guitar...because the mandolin/banduria strings are shorter and tighter, it produces higher pitch... "short and tight=higher pitch......long and loose=lower pitch"
The sound is produced by the vibration of the string.
http://emedia.leeward.hawaii.edu/frary/changing_strings.htm << go to that website for how to change classical strings. When changing guitar string it is best for your guitar depending on how well built it is, to change them one at a time. This keeps the tension on the truss rod. After you replace one string, tune it, and move on to the next.
i dnt no
second thickest if its a 4 string bass or 6 string guitar
Turning the peg or moving frets makes the pitch (frequency) of a guitar string go higher or lower.
The lowest string on a guitar is an E .........
you go to a guitar shop and get another string
if you are talking about an acoustic guitar i use the back of a hammer to pull the cap up
