Should I start teaching lessons? How?

The beginning...

I get asked frequently about how to start teaching music lessons from fellow musicians. I have been teaching private lessons for over a decade and I wished I started a lot sooner for the sole fact that I would have become a better musician faster. In my experience I found that in order to be viewed as a potential instructor I had to study and get organized. For years I had what my friend Jimmy Townsend called “Swiss cheese knowledge” due to the holes I had in my musical training. Well after I stuck my neck out taking on my first student it was time to start at the beginning. I bought guitar method books, music theory for dummies and most importantly I spied on other_ teachers. Sadly my first student didn’t know what was coming and tried to dump all the informatin I had been studying in 30 min which was a disaster. The poor kid just wanted to strum his new guitar and I got lost trying to explain to him how to harmonize the major scale. After a couple lessons I figured out our pace and outlined some rough lesson plans. My student and his dad were both happy and I felt good about our progress as well. 
If you feel that you are wanting to make some extras cash and learn more about your craft then by all means I recommend you start teaching. Maybe try with a relative or friend first to get your beak wet before you throw a price out there. Nowadays it so easy to post videos online or at least record them to critique your teaching skills.
