How Do I Convince My Parents Into Letting Me Get A Electric Guitar?can Anyone Help Me?

I think it is great that you want an  electric guitar, they teach electric guitar in school bands, at least in middle and high school, you can even earn a scholar ship to collage in band with that instrument. My daughter is in band and a friend of hers plays an electric guitar in the school band. Next year they are going on a field trip to london for a school band concert. To many kids are sitting on play station games, and computer chat rooms or what ever it is that they play on computers, closed off from being able to dream... To play an instrument that you like is a nice dream, and one that can take you some where in your life one day... Good luck, and i really hope they will get you one.

Prove to them that you are really interested in playing or even learning to play and you can do a better job at learning if you own your own, tell your parents all that,and I wish you luck because that is interesting and can take you a long way in life.......the best to you

In addition to these other answers, see if you can find a headphone amplifier. You can practice and hear yourself, and you can also link a stereo to your headset and jam with what you're listening to, and people outside of the room you're in won't be disturbed by the amp & speakers.

Get a friend to give you lessons on their guitar and borrow it and play it for your parents.  Hopefully they will be so impressed they will get you one of your own.
