I have heard how giving you are in so many respects of music schooling and I must say that I am impressed. You remind me of the pure idealism that we had in starting Apple. If I were young, with time, I'd likely offer to join and help you in your endeavours. Keep making people happy, not just in their own learning, but in the example you set for them.
Learn how to read tabs. Tabs will have six lines that represent your strings, along with numbers that designate where you should be placing your fingers. The numbers represent the fret in which you need to hold the string down. A 1 means the first fret, a 2 means the second fret, and so on. Numbers in a progression mean that you hold down the first individual fret and pick the note, then move to the next one, and so on in succession. Numbers on the same vertical line are meant to be played together simultaneously as a chord.
I have checked out Justin's site and found it to be comprehensive and informative. I have always felt that learning about music and especially music theory applied to the guitar, is helpful in finding your own unique voice on the instrument and expanding your creative horizons. Along with his insight into teaching and his fantastic abilities on the instrument, Justin has created a powerful go-to-place for anyone interested in exploring the instrument to their potential. Just don't hurt yourself.
YES! It is possible for you to learn to play guitar, regardless of your age. The oldest student of mine that I’ve heard from was 93… just starting to learn how to play guitar, and LOVING IT! The biggest hindrance to learning how to play guitar, at any age, is the belief that you’re not able to do it. So, if that thought has ever crossed your mind, toss it in the garbage can right now, and let’s move on.
There's an abundance of guitar information out there on the web, some good, some not. I stumbled across Justin Sandercoe's site a year ago and now tell everyone about it. The lessons are conveyed so clearly, concisely and in the most congenial way. The site is laid out logically as well so you can to go straight to your area of interest... beginner, blues, rock, folk, jazz, rhythm, fingerpicking... it's all there and more. Spend ten minutes with Justin and you'll not only play better but feel better too. From novice to know-it-all, everyone will learn something from Sandercoe.
You do not need long fingernails to play guitar. In fact, it's best to keep your fingernails short! As for the callouses, these may be unavoidable. If you would like to avoid them as much as possible, ask your guitar instructor about lowering the action of your guitar (the action is the distance between your strings and your frets) so that the frets are easier to press down on.
