Woodwind technique and conservation of energy

ByBret Pimentel

That people prefer to move in energetically optimal ways has been established for decades and now represents a central principle of movement science. … Energy optimization may also occur over the course of a lifetime, as years of experience could allow people to learn the optimal way to move in familiar situations and allow training to tune physiology to be more economical. An additional hypothesis—one that underpins many modern theories of motor control—is that people can adjust their movements to continuously optimize energetic cost.

Selinger, Jessica C., Shawn M. O’Connor, Jeremy D. Wong, and J. Maxwell Donelan. “Humans can continuously optimize energetic cost during walking.” Current Biology 25, no. 18 (2015): 2452-2456.

I certainly see this phenomenon in my own woodwind playing and teaching. How many times have you encountered these?

  • More resistant notes failing to respond because there’s just enough breath support for the less-resistant ones

  • Embouchures losing their shape, reverting to a neutral/normal mouth position

  • Voicing, such as the high, cold-air voicing needed for clarinet playing, or the low, warm-air one for flutes and double reeds, lapsing into a medium, luke-warm state that negatively affects tone, pitch, and response

  • Pitch sagging at ends of notes as breath support peters out

These are often addressed by teachers as “habits,” which may be true, but they may also be fed by the brain’s capacity—and priority—to micro-optimize our muscle use to conserve energy. No wonder they are difficult to overcome! Patience and persistence are necessary to train our bodies to put the right amount of effort into playing our instruments.

A factor in this is establishing a suitably high bar for success. For a beginner, the only question might be, “did a sound come out?” For a slightly more advanced student, it might become, “did the correct approximate pitch come out?” A more advanced player might examine the precision of the pitch, the quality of the tone, and the immediacy of the response, among many other factors. It takes a relatively low amount of energy to meet the beginner’s threshold of success, but potentially much more for the advanced player’s.

Additionally, this intentional use of greater energy resources must be managed carefully to avoid its misapplication, which can result in excessive tension.

I find that when I am playing at my best balance of efficiency and effort, an hour of playing a woodwind instrument leaves me feeling like I have done some light exercise; I’ll feel the mild and pleasant fatigue of having taken a walk or reorganized a bookshelf. Serious tiredness or soreness are warnings that I’m overusing my body. (Your results may vary depending on your physical capabilities.)

Be in tune with your own body as you play, and teach your students to be in tune with theirs, so that you’re in the sweet spot of working hard enough but not harder.

  • Decrescendo to zero

    ByBret Pimentel

    Woodwind players often struggle with decrescendos that quit too soon. (“Decrescendi” if you prefer.) It’s pretty disappointing to play a graceful phrase and have the last note end abruptly instead of fading down smoothly to zero.

    There’s not a special technique to deploy in order to make successful decrescendos to niente. This delicate dynamic effect just exposes a common shortfall in the fundamentals of tone production. Correcting this makes good decrescendos possible.

    Softer dynamics are produced on the woodwinds by shrinking the aperture (opening) in the embouchure. The flute has an independent aperture, which can be made smaller or larger at will. The aperture on reed instruments is built around the opening of the double reed, or the opening between the single reed and the mouthpiece. Reducing the aperture of the lips on reed instruments applies a slight pressure that squishes the reed closed a little, reducing its opening. (This is a lip movement, not a jaw movement).

    As the opening is reduced, airflow into the instrument decreases. At a certain point there is no longer enough power to keep the reed or flute air jet vibrating, so it stops. Hopefully, this occurs at such a soft volume that it seems like the note faded away completely.

    When the note ends too abruptly, check to make sure breath support isn’t decreasing with the decrescendo. Steady, powerful breath support as the aperture decreases equals an increase in air pressure. This keeps the reed vibrating as the opening and the volume decrease toward zero.

    Consistent, strong breath support and a flexible, well-formed embouchure are the keys to successful decrescendos.

  • Flute pressure against lip: survey of published opinions

    ByBret Pimentel

    My own past flute teachers gave me conflicting advice about how much the flute headjoint should press into the lower lip. One would pull on the crown of my flute while I played to make sure it came away from my lip with no resistance. Another would push the headjoint more firmly into my face as I played. (I improved under both teachers’ approaches.)

    I got curious about it recently and looked up what some flute pedagogues have had to say. I’m presenting my findings here without taking a personal stance (yet).

    It’s a little tricky to parse some of these, since many speak in terms of avoiding too much pressure, but don’t clarify whether that means to use as little pressure as possible or some moderate amount of pressure.

    In the avoid-too-much-pressure camp:

    A very important point to remember is never to force the mouth plate against the lower teeth as such forcing will limit the amount of flexibility after the embouchure has been developed.

    Do not press the head joint hard against the lips. Control of the tone must come from the lips themselves, not from pressure.

    In order to correct this problem [sharpness/pinching], the student should be certain that he is not pressing the flute against his lower lip, but rather thinking of the flute as resting lightly against the lip…

    Do not press the flute too tightly against the chin because too much pressure will alter the tone and pitch.

    Excessive pressure against the chin should be avoided.

    …the flute should rest lightly against the chin in order to leave the lips free and flexible.

    Nancy Toff: The Flute Book: A Complete Guide for Students and Performers, third edition. Oxford University Press, 2012, p. 94.

    [Common problems:] Too much pressure into the lip. The teacher should be able to tap the flute off of the lip with very little effort. … [for piccolo:] Too much pressure into the face, especially upper register. Excessive pressure makes high notes much more difficult if not impossible.

    Charles West: Woodwind Methods: An Essential Resource for Educators, Conductors, and Students. Delray Beach, Florida: Meredith Music Publications, 2015, p. 17.

    These are the ones I could find that seemed to advocate for at least some pressure, although neither is explicit about how much:

    Students should keep in mind the three points of pressure… [including] the lips pushing out against the flute…

    John Knight, “Flute Intonation,” in Woodwind Anthology, volume I, 1999 edition. Northfield, Illinois: The Instrumentalist, 1999, p. 529. Article originally printed in The Instrumentalist in 1989.

    “Keep a relaxed embouchure, but place the flute firmly on the chin.”

    John Knight is the only author to speak in terms of the lips putting pressure on the flute, rather than the reverse.

    In any case, among the sources I consulted, there seems to be some consensus that pressure of flute against lip should be light, or at least not “excessive.”

  • How many instruments do you play?

    ByBret Pimentel

    “So, how many instruments do you play?” I get this a lot.

    The way I prefer to answer is this: I play all of the major modern woodwind instruments, plus some folk and ethnic woodwinds.

    That answer usually doesn’t cut it. Read More “How many instruments do you play?”

  • What are registers?

    ByBret Pimentel

    “Registers” are a tricky concept in woodwind playing. Here’s how they work.

    For simplicity’s sake, let’s say I am playing a flute with a C footjoint. If I finger a low C, that closes all the instrument’s toneholes and produces a C4:

    Make your own woodwind fingering diagrams: fingering.bretpimentel.com

    As I work my way up the chromatic scale, I gradually open more and more of the flute’s holes. When I reach C-sharp 5, I run out of holes to open. (Using standard fingerings, that is.) To continue upward, the fingerings sort of restart—I close a bunch of toneholes again, fingering D5 in almost the same way I played D4. By the time I get to E5 I am using fingerings identical to the ones from an octave lower.

    I can play higher notes using the same fingerings I used for lower ones because I have moved into a higher register, which in this case is an octave above the lower register. On flute, I do this by changing something about my tone production; on reed instruments I get extra help from octave/register/”whisper” keys.

    If I continue my scale up to C-sharp 6, I run out of toneholes again, and move up to the third register, which is a fifth higher than the second. To play D6, I use a fingering that looks similar to G5, but sounds a fifth higher.

    So, for typical flute playing situations, we can consider the second register to begin at D5, and the third to begin at D6.

    But this doesn’t paint a complete picture in terms of the instrument’s acoustical properties. When the fingerings “start over” at D5, that’s not really starting over—I have left out the low C and C-sharp fingerings. And it turns out I can in fact play C5 and C-sharp 5 using those fingerings. The reason that flutists typically don’t is that the “standard” fingerings (with most of the toneholes opened) happen to work better for most situations, with regard to pitch, tone, and/or response. Likewise, when I reach C-sharp 5 and C-sharp 6, I haven’t completely run out of toneholes to open. If I open everything I have left (both trill keys, plus maybe the G-sharp key) I can get up to about D-sharp in either octave. But I usually don’t do that unless I have a special reason, because the standard fingerings are more usable.

    And starting the third register on D6 with an adapted “G” fingering raises this question again, but with an even larger gap. What about third-register notes using the fingerings from “low C” up to “F-sharp?” The answer is that those fingerings work, too (producing G up to C-sharp, an octave plus a fifth above the corresponding low-register fingerings). But, again, they aren’t as useful because of their pitch, tone, and response characteristics.

    So from an acoustical standpoint the first and second registers overlap in the C5-D-sharp 5 range, and the second and third overlap in the G5-D-sharp 6 range.

    When there’s overlap, there are fingering options available. The “standard” fingerings are the ones that have been chosen over the centuries by flutists as the ones best suited to most situations, but the others (sometimes called “overtone” fingerings or “harmonic” fingerings) can be used to good musical effect at times.

    The flute and most of the reed instruments follow the same pattern of registers: the second register is an octave above the first, and the third is a fifth above that. Additional registers above those are also used sometimes, spaced with increasingly small intervals. This series of intervals is a naturally-occurring phenomenon known as the harmonic series.

    The clarinet is an exception; due to its acoustical characteristics it uses only every other harmonic. This is why the clarinet doesn’t have an “octave” key, it has a “register” key that skips the octave register and goes straight to an octave plus a fifth.

    Understanding registers is helpful in navigating between them and in finding alternate fingerings for special situations. Happy practicing!

  • Preparing for a multiple woodwinds recital

    ByBret Pimentel

    Disclosure: As an Amazon Associate I earn from qualifying purchases, at no cost to you.

    For over a decade, all of my solo recital performances have been on multiple woodwind instruments. Last month I performed (twice) a recital program with pieces played on flute, oboe, clarinet, bassoon, and three saxophones. Here are some of the things I do to prepare.

    multiple-woodwinds-recital_mini

    • Practice the physical changes. I opened my program with an oboe piece, and followed that with a flute piece with a delicate entrance. As the recital approached, I made sure to follow each oboe practice session by practicing that flute entrance, to be sure I could do it under those conditions. Something that didn’t work very well: after the oboe, flute, and bassoon pieces, my hands and jaw tended to be a little tense for clarinet playing. If I were preparing this recital again, I would bump the clarinet to the end of my practice sessions to work on playing relaxed even when fatigued.
    • Practice the mental changes. If I can put myself into the right place mentally for the instrument I’m about to play, my physical technique seems to fall into place. Sometimes I will do some rotating warmups—play, for instance, some scales on one instrument, and then immediately play them on another, and another. That gives me a chance to practice shifting mental gears. Once I have my program order set, I also make liberal use of Post-it Notes to give myself reminders between pieces: “take a moment to relax embouchure,” “keep breath support strong in low register,” “clear moisture from octave vent.”
    • Make thorough checklists. With seven instruments on my most recent recital, I surely would have forgotten something—a bassoon seat strap, a case of clarinet reeds, a piece of sheet music. I made a detailed list and used it to set up for a dress rehearsal. Sure enough, there were a few things that hadn’t made it onto the list, and I was able to retrieve those items and add them to the list before the first public performance. When I traveled a few hours for another performance, I was confident that I had everything I needed.
    • Use good stands. Good ones are sturdy and make it easy to set down or pick up an instrument without fuss. Since I played flute, oboe, clarinet, and bassoon on the first half without leaving the stage, having some good stands kept things moving smoothly and let me stay focused.
    • Do thorough warmups. As the performance approaches, it’s tempting to practice in panic mode, and skip over things like warmups. I always play much better if I do my warmups faithfully all the way up to the day of the performance. I find that if I warm up slowly and thoroughly on each instrument before the performance (this might take a few hours with multiple instruments! I usually do it in the morning), then I’m able to switch between them more easily.

  • Practice technique: anchoring

    ByBret Pimentel

    This is a technique I recommend often to students who are struggling with notey passages. I can’t remember where I picked it up, or whether “anchoring” is my own name for it or someone else’s. No doubt credit for this belongs to somebody smarter than I.

    The problem that I sometimes see with my students (and, okay, occasionally with myself) is that fast passages are uneven and panicky. The student sees a long string of notes and frantically dives in, to the detriment of meter and tempo, and with notes accidentally omitted or added.

    Let’s consider this excerpt:

    from Debussy Première rhapsodie
    from Debussy Première rhapsodie (clarinet)

    It’s a challenging passage—shifting harmony, intervallic motion, awkward fingerings. This is a recipe for frustration using the old standby method of playing slowly with the metronome and gradually increasing the tempo. Instead, let’s set the metronome aside for a few minutes, and play the passage in an intentionally uneven way:

    with added tenuto-accent-fermata
    with added tenuto-accent-fermatas

    Put lots of weight on the metric pulses (the “anchor” notes): play them long, loud, and with emphasis. Hold each fermata long enough to scope out the next four notes, then move through them as quickly as you accurately can, coming to rest again on the next fermata. Repeat the passage in this way as many times as you can stand.

    Here’s what this accomplishes:

    • It makes you think about logical groups of notes, rather than trying either to process each note individually or to deal with the whole phrase as an overwhelming sea of notes. It’s the sweet spot between too much mental chatter and too little focus.
    • It encourages effective phrasing by treating the notes as leading toward downbeats.
    • It trains your ears to hear the notes in fours (at least in this 2/4 passage—try threes instead if the situation calls for it). Now as you return to playing the passage evenly, you are more likely to notice if you are omitting or adding notes.

    To transition from this technique into a more performable approach, gradually decrease the duration of the fermatas and the weight of the accents, while continuing to mentally emphasize the anchor notes and place them carefully in tempo (time to get the metronome back out). Also try spacing the anchors farther apart as an intermediate step—one at the beginning of each measure, for example, or every few measures as appropriate.

    Practice smart!

  1. Great article!

    People tend to add energy to solve problems. It’s counterintuitive to reduce energy to solve problems…but sometimes necessary.

    People like physical symmetry….balance the force of embouchure with the force of air pressure/flow. I had to practice using a gentle embouchure while increasing air pressure…making a crescendo or playing loud.
