At one level, the mechanics of playing the vibraphone are quite obvious and intutive: grab amallet and hit the bar, and you get a pretty good sound. However, there are other "extended"techniques; some offer sounds unattainable with traditional techniques, and others allow accessto notes above the range of the instrument. Please note that the sounds created here were all

done acoustically; no signal processing or audio "wizardry" was involved.

I. Harmonics

Vibraphone bars possess not only the fundamental tone of a given pitch (that is, the "written"note of a bar), but also the partials, or harmonics of that note. The first harmonic on a

vibraphone bar sounds two octaves above the fundamental tone. The use of harmonics allowsone to play notes which are above the high "f," the top note of the standard vibraphone range.Harmonics which fall within the standard range of the instrument (such as the example shown

below) will have a different sound compared to the actual note on the vibraphone.

There are two ways to notate the use of harmonics, and these are sometimes used together.One indication is the small circle shown under the note showing the bar to be played. The otherindicator is the diamond­shaped note head appearing on the pitch of the harmonic itself. Both

are shown in this example:

The technique for playing harmonics is fairly simple, and with a little practice, one canconsistently execute the technique. Simply touch a fingertip, or a mallet head, on the center ofthe bar (equidistant between the nodal points of the bar); then, strike the bar directly on a nodal

point.

II. Pitch Bending

While the vibraphone will never have the same flexibility of pitch as string, brass, or windinstruments, it is possible to bend the pitch of a bar down. This technique has been around for

decades, but its use is a relative rarety nowadays.

To bend a note on the vibraphone, one needs a "normal" vibraphone mallet (cord­ or yarn­wrapped), and a hard mallet (with a mallet head made of hard rubber or plastic, or a very hardwrapped mallet head ­ although this technique is difficult to execute with a wrapped mallet).

rest the hard mallet on a nodal point of a barstrike the bar with the "normal" malletpressing the hard mallet into the bar, drag it away from the nodal point

Several things to remember with this technique:

you may have to experiment with your choice of hard mallet.you may have to experiment with the amount of pressure used topress the hard mallet into the bar.the pitch will lower as you move the hard mallet away from thenodal point; if you get past the midpoint of the bar, and startmoving towards the other nodal point, the pitch will begin to rise.it is easier to execute this technique by pulling the mallet towardsyou, towards the center of the bar, rather than pushing it.

This effect may also be used to "bend" one pitch down to the pitch of another bar, if the secondnote is a half­step or whole­step below the first note:

III. Bowing

A vibraphone bar may be manipulated with a string instrument bow (almost always a bass bow,whose size is better suited to this use than a 'cello, viola, or violin bow). The sound which is

created is quite beautiful, lacking the strong attack of a mallet and producing a different tone asthe bar sustains.

Since this technique is borrowed from string instruments, the notation is borrowed as well.Notes to be bowed on the vibraphone are indicated with a down­bow (indicating motion fromthe handle, known as the "frog," to the tip of the bow) or an up­bow marking (from the tip

towards the handle); another method is the use of the term, "arco." (It is your author's humbleopinion that the choice of "up bowing" or "down bowing" is of minimal importance on the

vibraphone; it's much more significant to string players who have to agree on common phrasingfor their section in an orchestra.)

To bow a vibraphone bar, draw the bow vertically across the extended edge of the bar.Experiment with the amount of pressure used to hold the bow against the bar, with the speed at

which you draw the bow, and with the tension of the bow itself.

A few notes about bass bows:

String instrument bows can be very expensive, running into thousands of dollars for the finesthorsehair bows. A much better choice for a percussionist is to invest in the least expensive

fiberglass bass bows, which will last much longer than those with horsehair, and usually cost fiftydollars apiece or less. Any improvement in the sound one might get on a vibraphone with thehorsehair bow is negligible, if any, and certainly does not justify the initial expense or the added

expense of restringing the bow.

Also, the use of bass rosin on the bow is vital. Rosin will help the bow grab onto the bar as youdraw it, making it much easier to get the bar to speak. Additionally, remember to loosen the

tension on the bow when it is not in use; overtightening the bow, or leaving it tightened when notin use, will greatly shorten the bow's lifespan.

IV. Bowing Harmonics

Finally, just as one can use harmonics when playing with mallets, these harmonics can beaccessed when bowing as well.

Here is an example which begins with the fundamental tone, and by placing a finger on themiddle of the bar, the harmonic is created for the second note:

The extended techniques demonstrated in this lesson are more commonly associated with"classical" vibraphone performance, but there is no reason that a jazz musician cannot make use

of them as well.

(And finally, keep in mind you can bow marimba bars as well, along with xylophone bars,crotales, cymbals, triangles, music stands...)
