I'm having trouble w/ double tonguing below a G on the staff. My teacher has been working with me on this, but it seems the lower I go, the more trouble I have. Mind you, I'm on the comeback trail, about 6 months now, and when I played before I could not double tongue at all. My teacher has worked with me on this and I sound fine above a G. In the lower register, the notes just do not want to come out - at least not when I double tongue. Any tips on mastering double tonguing with lower register notes would be appreciated.
