So with that in mind, would you like to learn the guitar on your own or with others? The choice is yours at Guitar Center. If you prefer one-on-one instruction, that's absolutely doable - in fact, you'll find our schedule to be very flexible. Of course, learning in a group is an excellent way to meet like-minded musicians with similar tastes and share ideas on how to improve one another's craft. Who knows, you might even leave a group guitar lesson with plans to start a band with your newfound musical companions. Either way, our group and private guitar lessons are very entertaining and informative.
The next step is to figure out what gauge, or thickness of string is best suited to your playing ability and style. Thinner gauges are easier to fret and bend, and may be better suited for beginners, until callouses build up on the fingertips. Heavier strings tend to produce greater volume and fuller tone. Nylon strings are typically categorized as light, medium or heavy tension. Steel strings for both electric and acoustic guitars are categorized by the gauge, or thickness of the lightest string, the high E string, measured in thousandths of an inch, with .09 being a common size for an electric set. A set of electric strings may be labeled .09-.042 - this is the gauge of the lightest and heaviest string in the set. Acoustic sets are a little thicker, so a typical medium-gauge set might be .012-.054.
The E minor chord is one of the simplest to play because you only use two fingers Take extra care not to allow either of them to touch any of the open strings, or the chord won't ring properly. Strum all six strings. In certain situations, it may make sense to reverse your finger position so that your second finger is on the fifth string, and your third finger is on the fourth string.
The horizontal lines represent the frets on the guitar and the vertical lines represent the strings. The numbers listed let you know what fret number it is referring too. If there is an X it means don't play that string and if there is a 0 it means to play that string but do not press down on it anywhere. The black circles show you where to press down.
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.
