It is not essential to read music to play guitar but understanding a few basics helps. I show my students what they need to get started. If they want to learn more later on they can.

There is no "average" student and everyone learns at a different rate. However, assuming you have a weekly lesson and practice regularly I can usually have you playing something musical within 4-6 weeks or even less.

This is up to you but buy the best you can afford without spending a fortune. Entry level electric and acoustic guitars are available just over £100 - there are cheaper but I would not recommend them. Remember to budget for an amplifier when buying an electric. A reasonable practice amp can be bought for £75 upward. If you know anyone who plays it may be a good idea to take them along when you to buy your first instrument.

It is better to practice every day for half an hour than four hours once a week. Picking up the guitar every day will make you feel more comfortable as you become more familiar with the instrument. You are also less likely to spend time re- tracing the progress from the last practice session is you practice more frequently.
