If you are a music teacher yourself, make sure that you can be found. Connect to your community through some of the avenues outlined below. You may open up a whole new market for yourself.
1. Scan some local newspapers
2. Search online
Also, you can check out some online teacher directories. Some of the sites I've seen that seem to have a good amount of teachers listed include MusicPeeps.com, MusicTeachersDirectory.org, or if you want a nationally certified teacher you can check out the MTNA's Certified Teacher Directory.
3. Talk to music educators
4. Check with an arts center
5. Talk to church music directors
Whatever you choose to do as you search for a music teacher, don't be afraid to reach out to all the local music people that you can. Music is something that is designed to be shared. The more you know your local music scene, the better equipped you will be when you need someone with particular skills or resources.
