Hi! Welcome aboard!!

You've come to a great place to learn how to play guitar.

As you go through the lessons, it's OK to move onto the next lesson even if you haven't completely mastered the current one. You'll find that you'll fly through some and get totally bogged down on others.

When you move on though, make sure you conintue to practice the things you still haven't mastered.

As an example, let's say you've gone through a lesson that teaches a few chords. You get through that and next up is a lesson on changing between them in a song. This takes EVERYBODY time to master. Rather than staying on that lesson until you can switch chords flawlessly, move onto the next lesson. BUT, each day when you practice, be sure to practice those chord changes in addition to other stuff you've learned.

Don't be afraid to go back to an old lesson also. That's part of the beauty of the setup here - you can jump around if you want and you can repeat the same lesson over and over and over again without feeling embarassed in front of your teacher.

Best of luck learning guitar...let us know how it goes for you!
