You've finished! BUT The Journey has just begun...
Seriously. Now that you've learned these concepts, there are at least a 1,000 new doors that have been flung open and are waiting for you to walk through them! I encourage you to take every opportunity there is to play. Play guitar at your small group, in the worship band, on a mission trip, at work, at school, for friends and family, with other musicians. You can even start writing songs now that your familiar with song structures and the 7 chords of each key that work together!
One door that I highly recommend walking through is here at jwithrow.com. There will always be exciting new videos and programs being released so that you can continue to grow in your knowledge and skills--just as you've done with these 20 lessons. So please check out the other videos on this site as well as review old ones that may still need work. I'll continue to keep you in the loop of new videos and programs in the e-newsletter. Let's keep in touch :)
Happy playing and may God greatly bless you!
