Mix is an often misunderstood term (as are most in singing). Singers often refer to mix as "something less than belt," but in this episode, John discusses how to take your mix into the world of intense belting without the usual vocal fatigue and danger. The acoustics of mix are incredibly fascinating and open up an understanding of a wide range of contemporary vocal possibilities. Episode Links: Ken Bozeman "Practical Vocal Acoustics."
