Avoiding clarinet undertones: published techniques

Clarinet “undertones” or “grunts” are the unpleasant low sounds that happen usually at the beginning of tongued upper-clarion-register notes (about written G to C, above the staff). They are the lower register speaking out of turn—a clarion G’s undertone, for example, is the chalumeau C.

Fine clarinetists can more or less eradicate the problem, but there isn’t a lot of consensus or clarity among clarinetists about how exactly this is done.

This listing isn’t comprehensive, so I welcome submissions if you can point me toward published sources. And in many cases I have done some interpreting of the authors’ intents. (Julie DeRoche, for example, lists a number of embouchure specifics in her article, which I have reduced to “Ensure correct, stable embouchure formation.”) If you are one of the authors, or have particular insight into their thinking, I also welcome corrections.

How exciting to try out new instruments (or mouthpieces or headjoints or barrels or…) and to find one that really has a great sound! It’s a rite of passage for the young woodwind player, trying out a parade of shiny new possibilities, surrounded by parents, a private teacher, friends, and a salesperson with dollar signs … Read more

The role of tone exercises

Tone exercises are useful, sort of. Read last month’s post about tone for a reminder why tone exercises are only part of the process. Here is what tone exercises do: Excellent tone exercises demand solid fundamental tone-production technique, providing a chance to habituate useful muscular actions. Trevor Wye’s “Flexibility I” flute exercise is a perfect example. (I suggest you buy the whole Trevor … Read more
