Voicing: stable vs. flexible

I have discussed here previously the importance of proper voicing for woodwind instruments. In a nutshell, voicing is the configuration of the oral cavity, manipulated by moving the back of the tongue.

There seems to be some debate about voicing: is it something static, or something that changes from note to note? I find that the answer is, sort of, both.

For beginning woodwind players, tone, intonation, and response (virtually every aspect of tone production) can be improved by habituating a single, stable, “correct” voicing. When this is accomplished, an ideal woodwind instrument, which of course does not exist, would play perfectly in tune, with perfectly consistent tone from note to note, and with perfectly even and reliable response.

An instrument that is merely good will do these things well, but imperfectly. A more advanced musician can use small and temporary voicing adjustments to improve individual notes by altering their pitch, tone, or responsiveness. Doing this requires a “stable” voicing as a stepping-off point, fine control of the mechanics of voicing, and an ear trained to hear notes that are out of tune, uncharacteristic in tone, or problematic response-wise.

So, in general, when working with beginning students or others with significant tone production issues, the goal is to work toward a stable voicing that stays the same from note to note, but with more advanced students the goal is to learn to adjust the voicing ever so slightly to improve each note as needed.

  • Tonguing and language sounds

    Be wary of pedagogical approaches to woodwind articulation that depend on analogies to speech sounds.

    The most common, at least in the English-speaking world, is the idea that tonguing is like saying “too” or “doo.” And certainly there are significant mechanical similarities, especially with “too.” “Doo” doesn’t work as well because it is a voiced consonant, produced essentially the same way as “too” but with vibration of the vocal cords, an undesirable effect for woodwind playing (except for some extended techniques).

    Some teachers recommend something like “too” for crisper articulations and “doo” for gentler ones. If you compare carefully your whispered (unvoiced) “t” and “d” sounds, you may find that they are not, in fact, completely identical. My “t” gives a bit more explosive sound, because I release the entire tongue, and my “d” is softer because I tend to release only the tip of the tongue, keeping the back in contact with my molars. But this difference doesn’t apply to good woodwind playing technique, in which the back of the tongue must be kept independent from the tip in order to manipulate voicing.

    “Loo” is another one that gets mentioned sometimes for gentler articulations. This one also doesn’t work well if taken literally because (1) the “l” sound is voiced and (2) it leaks air around the sides of the tongue. (You can approximate an unvoiced version by whispering “lll…,” but that sound isn’t typically used in English.) A woodwind book I read recently recommends some additional oddities like “droo” or “thoo.” “Droo” doesn’t work well because it has a sequence of two consonant tongue positions, one of which is voiced. “Thoo” (presumably the unvoiced version) leaks air near the tip of the tongue.

    Another point worth making is that consonant sounds in English aren’t necessarily the same as consonants in other languages, so even if we select some workable English consonant sounds, it’s not a given that those are the ideal choices. (Plenty of study has already been done on this topic.)

    And that’s just the consonants. Assuming they are used as a shorthand for describing articulations, with an understanding that they do not precisely represent articulation technique, vowel sounds can still cause confusion. Consider the “oo” in “too.” Vowel sounds are loosely analogous to woodwind voicings, so it is best to match the vowels to the instrument. Is “oo” the right voicing to evoke?

    For low-voiced instruments, an “oh”- or “ah”-like vowel sound is a better match. (“Oh” is still problematic because English speakers pronounce it as a diphthong, two vowel sounds in sequence—this will cause unstable pitch and tone when applied to a woodwind instrument. To avoid this, we must borrow an “o” sound from another language.) For the clarinet, “ee” is the closest match. For saxophones, the vowel sound needs to be somewhere in between, perhaps near the schwa (ə) sound like the “a” in “about.”

    Language sounds can be used only as a very limited analogy for woodwind articulation technique—use them with care.

    Huey Lewis tells the story in Kansas City Magazine (strong language edited):

    Well, my dad was a jazzer and Zoot Sims died. And when Zoot Sims died, they had a benefit in San Francisco at Kimball’s or somewhere. …

    So I take him and sit down … and then I get a tap on my shoulder. I turn around, and it’s Getz. It’s really amazing … he’s wearing his horn and taps me on the shoulder, and my dad turns around and Phil Elwood turns around. And my old man goes, “Holy s***!”

    Getz says, “Why don’t you let me play on some of your s***? I can play that s*** too.” And I said, “Oh, why, yes sir, I’m sure you can.” And then he took a card and he wrote on it: “Stan Getz. Have sax, will travel.”

    He played beautifully, and on the way home, my old man says, “If you don’t take him up on that offer, I will never, ever forgive you!”

    Why scales?

    I recently asked one of my (woodwind) students why she thinks I make her practice scales. She didn’t have a ready answer, and I realized maybe I hadn’t been clear about the value of scales. Here are some reasons to practice scales (and arpeggios, and other methodical technical materials):

    • To develop good finger movement. Scales provide a systematic way to work each finger, and to work them together in just about every combination.
    • To build familiarity with the instrument. A rigorous scale routine makes you use every key and every fingering on the instrument.
    • To get comfortable playing in every key.
    • To explore the instrument’s range. Full-range scales are a good way to make yourself play in the highest and lowest registers of the instrument every day.
    • To provide a canvas for working on other techniques. Ever notice how woodwind instruments articulate a little differently on different notes? How different notes respond differently to vibrato? How some notes tend to be flat or sharp? Learn your scales well, and then use them as a way to take those techniques through every note on the instrument.
    • To train for musical situations. Most music is made up of bits and pieces of scales and arpeggios. Getting those patterns into muscle “memory” frees up mental bandwidth for sight-reading, ensemble, expression, and more.
    • To develop your ears. Internalize major, minor, diminished, whole tone, chromatic, and other modalities.
    • To satisfy requirements. If you are a music student at just about any level, scales are probably part of your lessons, exams, and auditions for the foreseeable future.
    • To have a familiar, habitual technical workout that you can improve upon for the rest of your life, without need for an étude book.

    Practice scales every day!

  • Woodwind dynamics and the embouchure

    There’s a lot of confusion about how different dynamic levels are produced on woodwind instruments. How do you think it’s done?

    If you said something like “use more or less air,” you are on the right track, kind of. But how do you put more or less air into the instrument?

    If you said something like “blow harder or softer,” you are asking for trouble. Adjusting volume by increasing and decreasing breath support causes all kinds of nasty problems, especially sluggish response, unfocused tone, and saggy pitch at softer dynamic levels.

    dynamics

    So what method is left to adjust the volume of air entering the instrument, and the corresponding loudness or softness (weirdly, also called “volume”)? Surprise, it’s your embouchure. Take a look in the mirror at your flute aperture, or look at the opening in your oboe or bassoon reed, or the opening between the tip of your clarinet or saxophone reed and the tip of the mouthpiece. By manipulating the size of this opening, you can control the volume of air passing into the instrument, while keeping your breath support powerful and steady.

    The opening isn’t large to begin with, so bear in mind that the adjustments needed are incredibly small. But your lip muscles are well-suited to very small, subtle, expressive movements—certainly more so than your larger breath support muscles.

    If you are an advanced player, you are probably doing this already, maybe without realizing it. But if you are struggling with dynamics-related problems, like unstable pitch during crescendos and diminuendos, or the inability to maintain tone at pianissimo, you might want to reexamine your technique.

    Try this: play a note in a comfortable range at an easy mezzo-forte, with powerful breath support. Without letting up on the breath support, apply just the slightest squeeze with your embouchure. (For me, the sensation is that my lips don’t really even move, they just firm up a little.) Gradually increase the squeeze—don’t forget to keep the support strong—and see what happens.

    Try it again, this time starting with the lips squeezing, and see what happens as you allow the embouchure to become more and more relaxed. This maxes out when the reed is almost completely free to vibrate at its widest amplitude, or when the flute aperture gets too large to maintain focus in the tone. (At this point you may be able to get more volume by straining harder with your breath support muscles, but notice what happens to your pitch and/or tone!)

    Like so much of woodwind playing, the real key here is breath support. If you remember to keep it steady, then creating dynamic changes from the embouchure is really quite intuitive and produces much better results.

    Incidentally, this is why recorders, pennywhistles, and other “fipple” flutes really have only one dynamic level; the opening can’t be manipulated effectively because it is rigid. Blowing harder or softer does change the volume but at unacceptable cost to intonation. (This is probably a major reason the transverse flute essentially replaced the recorder in Western music—it could play with dynamic contrast.)

  • Pedagogical recipes

    I want to follow up on something I touched on in my last post. I described in that post how I had my woodwind methods class evaluate some online pedagogical resources, and mentioned that I had them compare the information found online to the information presented in class. My idea was to prepare them to deal with conflicting information, which will be part of their reality as public school band directors.

    Woodwind pedagogy, unfortunately, is a mishmash of contradictory ideas. This is supported by a culture of hero worship of certain teachers and performers, a permissive editorial process for publishing pedagogical materials (increasingly so with the rise of the internet), and an attitude that music is not subject to scientific method.

    When conflicts exist between one school of thought and another, in some cases that is because one or both sides is incorrect. In other cases the problem is a communication failure: both sides are applying the same techniques in the same way, but describing them poorly (or at least differently). But I think there are other cases where the difference can be attributed to what I think of as different “recipes.”

    There are many ways to make a chocolate cake. Some cake recipes might be objectively better than others by some measure or another. Some might produce results that are generally satisfactory but especially suited to certain tastes. And in some cases, two different recipes might produce results that are very similar. In those cases, the way the ingredients and techniques balance is significant: one recipe might call for two eggs instead of three, but has more of another ingredient that makes up the difference, or a difference in baking time and temperature.

    I think a similar thing can happen with “recipes” for woodwind playing. Equipment preferences are a fairly clear example: one clarinet teacher might favor very stiff reeds, while another prefers softer ones. Both might produce excellent results, so long as they are balanced properly—the first teacher probably balances stiffer reeds against mouthpieces with a more closed tip, and the other might use softer reeds with more open mouthpieces. One oboe teacher might clip his reeds to 70mm while another clips hers to 69.5mm, but they probably balance this with narrower or wider shaper tips, or tweaks to any of a dozen other variables.

    Playing techniques are a little more abstract and complicated to separate out, but I think the same concept applies. One bassoon teacher might encourage some jaw movement when articulating lower notes, while another teaches a more stable embouchure, but it’s always more complicated than that: the technique’s usefulness and effectiveness has to be evaluated in the context of each teacher’s approach to breath support, voicing, embouchure, equipment, and more.

    The idea that I wanted to bring across to my class is that, for band directors or other musicians and music educators who might not be specialists in each of the woodwind instruments, it is important to beware little pedagogical proverbs taken out of context. Something like “firm up your embouchure” or “use a stiffer reed” or “use the alternate F-sharp” can seem like a quick and digestible solution, but can’t be applied casually and without understanding of the larger picture.
