Quite a few years ago I used to teach guitar to kids on the side to try to supplement my meager, struggling musician income. I just did it out of my house and charged five bucks an hour (it was the 80’s).
My cancellation policy was that the students could quit whenever they felt like it with no finacial penalty. I was not fond of trying to keep plodding along with a kid who had lost interest in the instrument.
It takes a certain set of skills and qualities to teach an instrument, especially to children.
You have to be patient. You have to be able to sit there and listen to the same ear-splitting mistakes over and over again. You have to remain upbeat and encouraging and keep finding the things they’re doing right.
You have to be able to connect with kids but you also have to project some authority. You have to control the lesson and not get sidetracked. Don’t ket the kids draw you into long conversations about professional wrestling or Spiderman 2. Stay on task. It’s very easy to get off track when you’re working with kids. They get bored and distracted easily and you have to direct them back when they start to drift away.
You have to know what your lesson plan is going to be. You can’t just wing it. You need something written down. I know this from hard experience. I have faked my way through lessons I had not prepared for and it did not go well.
Above all, you have to know how to communicate. You may feel like you understand the instrument very well but it can be surprisingly difficult to convey certain things verbally, especially to kids. Practice how you’re going to explain things at every step. Find someone who doesn’t know anything about music, practice an explanation of major scales and triads and see if they get it. If an adult won’t get it immediately, a child won’t get it.
Keep the lessons simple and focused. Don’t overload them with too much info at once. Give them only one or two new ideas to work with for each lesson.
I always gave them at least one new song to learn at each lesson, starting with the first one. I used to teach a simplified fingering of “Knocking On Heaven’s Door” but any simple two or three chord song will do. You can truncate the chords to just the top three strings at first. It doesn’t have to sound like Pete Townahend. The idea is just to get them playing songs rather than exercises because songs are more fun and they will be more likely to practice them.
Tailor your lessons as much as you can to the kind of music the kid personally likes, Teach him those kinds of songs. Don’t waste time on the Mel Bay “Down in the Valley” stuff. Teach them to play stuff the recognize and like. Feel free to simplify songs at first. Paraphrase them, strip them down to the basics. They’ll still like them.
A lot of kids, I’d even say most kids are going to get bored or lose interest after just a few lessons. They’ll find out it’s hard, their fingers will get sore, they won’t practice and you’ll be repeating lessons. When this happens, ask the kid if he’s sure he wants to go on, and maybe talk to the parents about it. If a kid won’t practice you will never get anywhere. The instruction is a very small part of learning the instrument. 99% of it is practice. You can teach a kid the chords but if he doesn’t practice, he will never progress. If that was going on for me I would tell the parents that they were wasting their money and maybe the instrument wasn’t for him. I actually tried to be very cognizant of a kid’s relative interest and I always let them know that music was supposed to be fun and if they weren’t having fun then they didn’t have to do it. I wanted them to feel they could quit at any time. I didn’t want them to ever feel like it was something they had to do. I still tried to get it across that the work would pay off if they stuck with it, though.
I hope some of this helps and good luck with your endeavor, It feels really good to take a student from the very beginning stages to a level where they can actually play. It’s a nice sense of accomplishment to know that “I taught him/her how to play.” The one kid that loves the instrument, who practices all the time, who can’t wait to learn the next thing. The kid who you realize has talent. That one kid makes it all worthwhile.
