Pushing in and pulling out

As a follow-up to last month’s post on playing in tune, I would like to revisit the idea of adjusting woodwind tuning mechanisms (generally by the “pushing in” or “pulling out” of some joint of the instrument). Note that this information is probably of most value to advanced players; beginning and intermediate players should be focusing their intonation efforts on breath support and voicing.

A simplistic view of “tuning” is that “pulling out” makes the instrument play a little flatter and “pushing in” makes it play a little sharper. The problem is that not all notes are affected equally.

For example, let’s keep the math simple and imagine an instrument that is 100cm long with its tuning mechanism pushed all the way in. And let’s imagine that instrument has a tonehole that can be opened to give the tube an effective length of 50cm.

tuning_percent_before

Now suppose that you pull the tuning mechanism out by 1cm. The lengths of the tube for the notes are now 101cm and 51cm.

tuning_percent_after

They have changed by the same absolute length, but not by the same percentage. The shorter-tube notes (those with more open toneholes) are more dramatically affected by changes in the tuning mechanism than the long-tube notes are.

This is a problem without a tidy solution. A high-quality instrument is built to play at a specific pitch standard (A=440, A=442, etc.) with the tuning mechanism adjusted to a precise location and at a specific temperature. The “easiest” way to play in tune is to own an instrument built to your preferred pitch standard (such as the one your ensemble tunes to), play only in spaces having a suitable temperature, and adjust the tuning mechanism to that precise spot every time. In reality, of course, we need the flexibility of a moveable tuning mechanism to adapt to a variety of circumstances, but we have to be aware of the consequences of pushing in and pulling out.

An additional wrinkle, so to speak, is that adjusting tuning mechanisms can introduce perturbations to the instrument’s bore. Skilled instrument makers can purposefully create perturbations to improve an instrument’s intonation, but undesirable perturbations can have non-intuitive effects on the instrument’s scale.

Here’s what I mean by the tuning mechanism creating a perturbation. Notice how when the tuning mechanism is pushed in the bore is a consistent width, but when the tuning mechanism is pulled out, there is a wider spot in the bore:

perturbation

This is one of the benefits of tuning a clarinet or bassoon flatter by switching to a longer barrel or bocal: you get the additional length you need without creating a bore perturbation (though remember, notes are still affected unequally). A workaround for clarinetists is to use tuning rings, preferably matched to the instrument’s bore size at that joint, to fill in the perturbation.

Most of getting tuned up has to do with obtaining a high-quality instrument and playing it with high-quality basic technique (good breath support, voicing, and embouchure). That last little bit of improvement is complex and elusive, and understanding some of the reasons for that can help you get there.

  • Woodwind instrument “care kits” are bad news

    Congratulations on your new student-level flute, oboe, clarinet, bassoon, or saxophone! Your music store’s friendly sales associate (or your online retailer’s auto-suggest software) is probably insisting that you purchase a “care kit” as well. This kit ostensibly contains all the items you need to keep your new instrument working well and looking shiny. I recommend that you do not buy it, because it is, at best, a waste of your money, and, at worst, a hazard to the instrument’s wellbeing.

    Here are some of the items that frequently appear in these terrible kits:

    • Polishing cloths. Chemicals or polishes (liquid or embedded in cloths) can gum up pads and mechanisms. Students can “polish” their instruments with a soft, dry cloth, like a piece of an old t-shirt. Your repairperson can remove the keys and do a more thorough polishing safely.
    • Swabs. Woodwind instruments should definitely have swabs, but beware the kinds in these kits.
      Silk is preferable for pull-through swabs (oboe, clarinet, bassoon, saxophone) because it is absorbent and compressible, so it’s less likely to get stuck inside the instrument than a cheaper felt swab. Even for a student instrument, it’s worth a few extra dollars to get silk.

      "headjoint swabs"
      “headjoint swabs”

      For flutes, avoid “headjoint swabs” that are little oddly-shaped pieces of chamois (or a synthetic version), unless you want to have to fish them out of the headjoint every time you try to use them. Instead, use the cleaning rod that came with the flute, plus a strip of fabric cut from an old bed sheet.
      The fuzzy “cleaning” brushes that look like giant pipe cleaners, that you insert and leave inside the instrument, do exactly the wrong thing by keeping all the moisture inside the instrument, instead of wiping it out like a good swab does.

    • Cork grease. Yes, for instruments with parts that friction-fit together with cork, such as clarinets, oboes, and saxophones. Flutes don’t have any corked joints (though some piccolos do). Some bassoons have corked fittings, but some have thread wrappings instead. Use cork grease on cork only—never on thread-wrapped or metal-to-metal joints.
    • Screwdrivers. Yikes! Woodwind instruments often have “adjustment” screws. Bored students and well-meaning dads can’t resist just tightening everything up, just to make sure. This leaves the instrument in unplayable condition, and only a professional can put those adjustment screws back just right.
    • Reed guards/cases. Yes! Keeping reeds in one of these generally keeps them intact and in playing condition for longer than the disposable ones that the reeds come in. Those little plastic or cardboard sleeves that clarinet and saxophone reeds come in don’t keep them flat when they dry. And oboe and bassoon reeds often come in tubes that are too flimsy for regular use, or hinged plastic cases that come apart in the instrument’s case, leaving the reeds to bounce around unprotected.
    • Mouthpiece brushes. These are basically little vegetable brushes, with scratchy synthetic bristles and the dreaded twisted-wire core, much too aggressive for cleaning clarinet and saxophone mouthpieces. Instead, try a gentle rinse with room-temperature water and a drop of mild dish detergent. Stephen Howard’s vinegar-and-cotton method is good for occasional deeper cleanings.
    • Neck or bocal brushes. Probably too aggressive for use on these particularly delicate and crucial instrument parts. Plus, a strong risk of getting something stuck.
    • “Tone hole cleaners.” These are usually garden-variety pipe cleaners. Tone hole cleaning isn’t a task for beginners to do. The pipe cleaners’ twisted-wire cores can damage toneholes, the instrument’s bore, or pads.
    • “Pad papers.” It’s really tempting to use a lot of pressure with these, which can distort pads and cause leaks. Some are coated with a powder—these operate on the same principle as getting some gum stuck on your shoe, then stepping in some dirt so the gum won’t keep sticking to the sidewalk when you walk.Pad papers and other powder treatments should be an emergency treatment applied wisely and carefully by a knowledgeable musician, not a daily treatment applied badly by a student.
    • Key-dusting brushes. Gently removing some dust from the instrument’s mechanism isn’t an all-bad idea, but be advised that it’s easy to knock springs and things out of place. The brushes in these kits usually have twisted-wire cores, which can scratch instruments’ finishes. Instead, consider using cheap kids’ watercolor paintbrushes. Or, even better, make sure the instrument gets professional maintenance and cleaning at least once a year.
    • Key oil. No, no, no. This is a job for a professional to do. Besides, the kind in these care kits is usually cheap 3-in-1-type oil. Even if applied properly, it tends to drip back out of the keywork onto fingers, or worse, pads.
    • Bore oil. Absolutely not. Using this at all (only in wooden instruments) is controversial. When you bring it in for its annual maintenance, your repairperson can apply bore oil properly and safely if they deem it necessary. (My opinion: if in doubt, don’t bother.)
    • Care manuals. These are generally provided to justify the other items in the care kit.

    Skip the care kit—they are a way for retailers to squeeze a few more dollars out of you at purchase, and then more when you bring the instrument back in to fix the damage you have done with your brushes and oils and screwdrivers.

  • Fox bassoon crutch modification

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

    I use an inexpensive Fox plastic crutch on my bassoon. The shaft has always been a little too short for my preference, and I wasn’t interested in paying for a custom-made one, so I decided to attempt removing and replacing the shaft. I’m sharing this information here in case anyone else wants to do the same.

    I wasn’t sure if the stock shaft was glued or molded into the plastic or if I would be able to remove it without destroying the crutch. But a little heat, slowly applied to the shaft not too close to the plastic, did the trick and the shaft pulled right out. (It’s hot! I used pliers.) The plastic inside the hole was slightly mangled, so I reamed it out a little with a drill bit.

    I replaced the shaft with some brass that I had on hand. 3/16″ turned out to be too thick to fit into the bracket on my bassoon, but 5/32″ (just under 4mm) worked. The stock shaft seems to be somewhere in between. I cut the brass a bit too long with a Dremel cutting wheel, so I could gradually trim it down until it was just right.

    I cut some shallow notches into one end to imitate the stock shaft, hopefully giving the glue something more to hold onto. My 5-minute epoxy had hardened, so I substituted some gel-type cyanoacrylate (“super”) glue.

    After a little trimming I found the length I wanted. (I use my crutch in this position, which I think is less-common, but gives me the “ball” of the crutch right in the palm of my hand which feels good for balance.)

    With my minimal skill set and tools, plus a little trial and error, this was a manageable and successful project.

  • From Google: Lord of the Rings on whistle, low A on bassoon, woodwind commonalities

    Classes are canceled today due to a freak snowstorm in my little Southern college town. (Typical yearly snowfall: 0 inches. Yesterday’s snowfall: 5 inches.) So instead of teaching a woodwind methods class and rehearsing on contrabassoon with the university’s Wind Ensemble, I thought I would take a few minutes to do something I’ve been seeing some of my favorite bloggers do lately.

    With some simple traffic-tracking tools, I can see what Google searches are leading people to my website. Most times, to my satisfaction, their search brings them to highly relevant content on my site. Other times I know they are not finding quite what they are looking for. So I’d like to address a selection of the searches that have brought people here unsuccessfully lately, and hopefully future searchers will find what they are after.

  • Physical factors and beginning woodwind players

    Ideal flute embouchure?
    Ideal flute embouchure?

    A disturbing amount of flute pedagogical literature includes drawings or descriptions of what types of lips are good for flute playing and what types aren’t. Usually the lips deemed flute-appropriate are perfectly symmetrical and not too thin, not too wide. I tend to think that those kinds of distinctions are garbage, as are the descriptions of the “right” lips for clarinet or oboe playing or the suggestion that students with natural overbites are born bassoonists.

    I also object to the instrument-assigning days that I understand happen in many beginning band programs, at which students are allowed to try several instruments, and assigned based on the “aptitude” that they show in their first 30 seconds holding the instrument.

  • 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.
