	overblowing (Site not responding. Last check: 2007-10-20)
		Overblowing is producing a different note in a wind instrument by forcing air harder.
		In most more developed instruments, this transition from lower to higher registers is aided by a "register hole" which encourages a vibration node at a particular point in the pipe, causing the vibration pattern to change, so overblowing is not so important.
		Overblowing is a problem that arises when playing the bagpipes.

	Flute
		One advantage of the flute over the recorder is that the player has direct control over the angle at which the air from the lips strikes the embouchure hole.
		Rolling in or out with the lips relative to the edge gives the player a greater range of volume and expression, and aids the process of overblowing to achieve the higher register.
		This is achieved by a process called "overblowing" the flute, and the notes produced are said to be in the "upper register" of the flute.

	Harmonica Central - Howard Levy - Levyland
		Overblows and overdraws provide a player with all of the notes that are ”missing” from the diatonic harmonica.
		When you are ready to try overblowing, practice blow bending 8 blow, and getting it to bend very smoothly at moderate volume, up and down, so there’s no crack where the pitch changes- I will assume that whoever is reading this knows how to blow bend.
		You can also get 1 overblow using mouth breathing- no breathing from the lungs through the throat at all, just pushing air quickly in and out on the first hole with your tongue making that “who” shape, getting D and Eb on draw and blow.

		In reed woodwinds it refers to the situation that the reed vibration frequency is controlled by a higher oscillation mode of the air column.
		Overblowing is caused by a particular combination of embouchure and input parameters, sometimes assisted by a special fingering.
		Similarly, in conical bores overblowing establish reed vibrations at frequencies which are about 3, 5, 7 etc. times the lowest mode.

		That's the limitation of Howard's individual overblow technique, which - dare I say it - is only middling (it's only one small part of a package of musical abilities which, in aggregate, are quite amazing).
		I'm far from being the best overblower in the world, but I've played a sustained overblow for Howard and favorably surprised him with it.
		Overblowing was first recorded in 1929, and was recorded again around 1970 by both Toots Thielemans and by Will Scarlett - Will taught me the technique in 1974 in a room full of people who seemed amazed that I'd never heard of it.

	tenhole - Tinus [1.] - introduction
		I am what is sometimes called an overblow player and one of the few diatonic harmonica players that take the radical approach of playing everything on a single diatonic harmonica.
		Although the use of overblows has started to become widespread among bluesharp players the use of the diatonic harmonica as a fully chromatic instrument is still rare.
		Overblows and overdraws can be played on most diatonic harmonicas.

	Musical Instruments - MSN Encarta
		The keyed trumpet and keyed bugle (see Bugle) became obsolete only when valves were widely adopted for brasses in the 19th century.
		In many aerophones, overblowing (drastically increasing the wind pressure) forces higher harmonics to supersede the fundamental pitch.
		A bugler, whose instrument is a tube of constant length, can thus play tunes by overblowing to produce various harmonics.

	Future of the Harmonica
		However, even on a well set up instrument, overblowing is still a very difficult technique to master, especially throughout the range, and several new designs have been developed to make it easier to achieve clear and strong overblows on all notes.
		A different approach to overblowing, but which is also intended to enhance the expressive and chromatic abilities of the diatonic harmonica, is to allow more notes to be bent in pitch.
		This means that overblowing is not possible, and the tone is not the same as on an unvalved diatonic - and these factors, as well as the instrument's larger size (meaning hand effects are not so easy), would be considered drawbacks by staunch diatonic overblowers.

		If the vibration in the instrument without overblowing consists of frequencies of 100 Hz, 200 HZ, 300 Hz etc., the frequencies after overblowing may be 200, 400, 600 Hz etc., or 300, 600, 900 Hz.
		The fundamental frequency and the overtones form a harmonic series in the case of overblowing as well, and the pitch of the fundamental will be determined by a similar "tug of war" as without overblowing.
		Overblowing on such an "instrument" (which could only exist in theory) would be no problem: the octaves and most other overtones are perfectly in tune.

	Best of Harp-L - Overblows
		It's clear that an overblow requires a certain kind of air pressure (Yes, somewhat like a blow bend,) the same is true of all the "micro-tones" in the OB bend.
		As an aid to overblows, I might suggest starting by playing the draw note, which gets the draw reed activated (the draw reed is the one that is the overblow reed), then immediately blowing in the hole, as Larry is suggesting, using a blowbend type of action.
		If you are having difficulty with overblowing, you might still try overdrawing, as some players hit their first overbend in that way.

	Chicago Symphony Orchestra - Woodwind instruments
		Overblowing is also different from one woodwind instrument to the next.) Overblowing causes the air column to vibrate in partial lengths, meaning at higher frequencies, and the result is higher pitches.
		When used in combination with covering and uncovering holes, overblowing greatly expands the range of possible pitches on a woodwind instrument.
		Since there are far more holes on a woodwind instrument than a player has fingers, woodwind players must cover and uncover the necessary holes by using an array of metal keys, which are part of a system of levers, rods, and springs, all connected to felt-padded hole covers.

		It is primarily the keywork that is used for sound production, whereas the technique of overblowing, so important on brass instruments, plays only a subordinate role on the flute.
		The high notes are generally produced by means of special fingerings rather than by overblowing.
		Exceptions are made in difficult passages, however, where it is not unusual for the notes D6 through A6 to be produced by overblowing to the 3

		And the German sax man has always maintained that he was happy to hear Ayler's earliest discs because it meant that someone else beside him was experimenting with overblowing, multiphonics and the non-song form.
		While not as mind-altering as Machine Gun, which in 1968 extended this cacophony to a larger group, For Adolphe Sax, initially issued on the saxophonist's own Bro label, is still a pretty impressive achievement.
		As an aside, one wonders if the saxophonist's frenzied playing on the 16 plus minutes of "Morning Glory" was what first created the tale that he literally burst a blood vessel during performance; it certainly seems to be hernia-creating music.

	FAQ - Fujara playing technique
		Fujara has 3 holes (vents) and the height of tone is decided mainly by the strength of in-blown air achieving thus various overtones.
		Fujara overtone overblowing (breathing-like) playing technique feels very natural and is easy to learn for anybody.
		Fingering is used mostly in the lower bass series (lower three octaves) while on the other hand the fourth, highest fujara octave is played purely by overblowing the overtones where the height of tone is decided by the sthrenght of the inblown air.

	The Future Of The Harmonica by Brendan Power / Free Reed Festival 2000
		When bending and overblowing are combined on the humble blues harp, suddenly the instrument is capable of a fully chromatic scale - leading to all sorts of possibilities which weren't conceived of before.
		Since overblowing requires a very fine reed setup to work properly, the understanding of how reeds function and how to make them work better has grown enormously in recent times.
		The first of these, Henry Bahnson's Overblow Harp, was a modified Hohner Golden Melody model with a slide that, when activated, moved over the surface of the reedplate to cover the relevant reeds.

		As on all woodwinds it is primarily the keywork that is used to produce the various pitches.
		The technique of overblowing - the bassoon overblows to the octave – is largely replaced by the use of speaker keys.
		The notes from F#3 to D4 are produced by overblowing the fundamental scale (first-degree overblowing), the fingering is the same as that for the lower octave.

		I'll start off with a proven idea that has not been taken advantage of, ergo, overblowing an ocarina into a second mode (octave is incorrect here) above the fundamental pitch.
		There are 6, 7, or 8 holes in front and sometimes a dorsal thumbhole too and has the same range as a Budrio "sweet potato".
		If we take the gemshorn internal shape and stretch it out to a narrow cone and move the lowest hole to the end, we have the basic shape of a recorder.

	Air Column Use by Musical Instruments
		The playing range of woodwind instruments is extended by the existence of upper registers which allow them to excite upper harmonics of the air columns.
		In the flute the process is called overblowing.
		The upper register is an octave up in such instruments since they act as open-ended cylinders.

	The Not-Quite-Harmonic Overblowing of the Bassoon
		This reduction is analogous to shortening the bassoon’s air column (pipe) by opening tone holes to raise the pitch from Bb1 to F3 (open F).
		A pipe in the shape of a perfect cone will overblow harmonically – it will produce an array of pipe resonances related to one another by a harmonic ratio.
		We noted earlier that the bassoon’s full-system, second-mode response is essentially in tune – it overblows at a harmonic ratio of 2:1.

		Overblowing results when contractors blow in fiberglass to the depth listed on the bag label but cover a larger area than prescribed.
		“Overblows of 25% are common in the industry, with some jobs overblown as much as 50%”, says Larry Helminiak, former president of the ICAA, who continues, “the Insulation Contractors Association of America has been engaged in a 15-year crusade to put an end to this.”
		Even if they do, they won’t spot overblowing because the fiberglass is probably at or near the proper depth, but not the proper density.

	Andrew Lenz's Bagpiping Competition #19
		Scott called me over and told me basically what he was going to write on the sheet, that is, overblowing on the top hand which also affected the drones tuning with the chanter, bad grip in the first line (but fine after that one), birls not consistent.
		I think the overblowing may have been subconscious effort to keep the reed from choking.
		Sandy called me over and told me that aside from overblowing, I was hitting the C (from D) before cleanly finishing the G gracenote of the doubling—that I need to lift the G finger higher.

		Howard advised me that half of overblowing is setting the harp up properly; in response to my question about whether he could reliably get all the overblown pitches on every harp, his answer was yes, mostly.
		Howard's lines, dazzling though they were, did not have a uniform tone and attack; it was often obvious when a note was played with a bend or an overblow.
		I couldn't help but feel that the excitement of being to able to get all the notes is leading the adherents of fully chromatic technique to ignore a lot of very basic stuff related to how the notes actually sound.

		The other way is to increase (to varying degrees) the tension of the lips and the pressure of the breath.
		This is called “overblowing.” Overblowing changes the pressure of the air column within the tube, causing it to vibrate in partial lengths, at higher frequencies.
		Before that, all horns were “natural horns.” To produce a series of different notes on a natural horn, the player must rely entirely on lip technique (overblowing) and handstopping.

		His tenor saxophone sound is gigantic, with a warm and wide vibrato, and an attack that runs from the gentle caressing of notes to extended shards of intentional overblowing.
		His clarinet playing has the same command of sound, with a massive, piercing tone and a conception that integrates the entire history of the instrument.
		With his broad tenor sound and the quartet's tenor sax-trombone front line, this music may sound quite like a 1966 Archie Shepp record.

		With overblowing, we use lip and breath technique to "kick" the tone up into a higher range.
		An octave is a doubling (or halving) of a note's vibrational frequency, which our ears interpret as being the same note, but in a "higher" or "lower" range, respectively.
		Thus, they're forced to use higher lung pressure as an aid in overblowing.
