Idiophones
|
Sticks
|
Each singer holds a pair of wooden
sticks, one in each hand, and provides a percussive rhythm. One, long and
slightly flattened stick is generally grasped in the middle and held flat.
The other, more rounded and held towards the end, is brought sharply and
cleanly on to the first. The paired sticks can vary considerably in shape.
|
Boomerang clapsticks
|
These provide a similar function
as the sticks. At times they may be shaken so as to provide a continuous
rattle.
|
|
Handclapping
|
Handclapping and slapping various
parts of the body are used by singers of both sexes, sometimes as a
substitute for a pair of sticks.
|
|
Set of percussion sticks
|
Sometimes referred to
"gongs", the set of three or four variously-lengthed wooden sticks
hit with a stick are used only in Yabaduruwa ceremonies.
|
|
Percussion tube
|
A percussion tube, the
"hollow log drum" is used with the Ubar ceremonies. Other percussie
idiophones include a stick beaten on a shield, a stick beaten on another
stick lying on the ground, and the women's bark bundle hit on the ground.
|
|
Rasp
|
The Kimberley Tabi songs are
accompanied by a rasp. A notched stick, or the side of a spear thrower is
scraped by a second, smaller stick.
|
|
Rattle
|
Island style songs from Cape York
are accompanied by bunches of seed pods held in the hand.
|
|
Membranophone
|
Skin drum
|
A single-headed hour glass shaped
drum, whose head is made from lizard or goanna skin, or on at least one
occaision the rubber from a tyre inner tube, is heard from Cape York, with
both traditional song types and island dance. The open end is sometimes
shaped like the mouth of a crocodile.

Didjeridu
|
The didjeridu is usually formed
when a branch of a tree, naturally hollow, is further hollowed out by nesting
termites. Aboriginal Australians cut these branches to a suitable length
(approx. 1.5 metres), hollowing out both ends a little more and sometimes
smoothing the mouthpiece with gum. Blown with vibrating lips, the didjeridu
gives a fundamental note with a rich and complex harmonic series. Constant
air pressure is maintained by simultaneously blowing out through the mouth
and breathing in through the nose, using the cheeks as a reservoir.
Considerable stamina is required for this technique and a good didjeridu
player is considered capable of sustaining fast energetic rhythmic patterns
throughout a given song. A skilled player is highly respected and may travel
with a professional songman to enhance trade meetings or other interband
meetings.
The function of the didjeridu is
to provide a constant drone on a deep note, somewhere between D flat and G
below the bass clef. This drone is not a simple held note, but is broken up
into a great variety of rythmic patterns and accents by the skilful use of
the tongue and cheeks. Nor is it constant in timbre, for many different tone
colours are achieved by altering the shape of the mouth cavity and the
position of the tongue and by shutting off various parts of the anatomy which
act as resonating chambers for the human voice.
It is not, however, in the
manipulation of the droned fundamental, nor in the slight rise and fall of
pitch used to accent a rhythm, that the great skill of a didjeridu player
lies, but in his use of two entirely different notes, which are alternated in
rapid succession to form complex and fascinating cross-rhythms. These two
notes are not haphazardly chosen, but invariably are pitched a major tenth
apart, the upper note being the first overtone. The physical explanation for
this overtone being a tenth above the fundamental has not, so far, been
found; but probably lies in the fact that the tube is slightly and
irregularly conical. One would expect either the octave (for a conical pipe)
or a twelfth (for a cylindrical pipe) to result, but the actual interval is
never less than a tenth nor more than an eleventh.
