I am currently offering lessons in overtone/throat singing at $20 a lesson. They go from 30min to 1 hour depending on what material is being covered. I also offer guitar, violin, and piano lessons. Lessons focus on learning fundamental technical skills through ear-training and improvisation.
I do workshops in Junk Instrument construction, songwriting, sculpture, and winemaking.
I have lots of experience with kids of all ages and would welcome any opportunity to come to a school to do a workshop. The fees for workshops are fairly flexible. The amount of time and materials I would need to acquire have a lot to do with the price, also the number of participants and budget considerations.
