A great idea for a special to offer as a music teacher would be a "birthday package". Offer a package of 10-15 music lessons in a reduced price with a special coupon that can be offered as a gift certificate. This goes well when the additional birthday gift was an instrument, or when friends and family want to re-awaken musical abilities in a loved one.
It also allows you to know that you are getting paid ahead for 15 lessons, and therefore gives you some wiggle room with the price.
Publish this deal on your website, in forum ads and in your music teacher classified ads.
