Modern didgeridoo designs

Modern didgeridoo designs are distinct from the traditional Australian Aboriginal didgeridoo, and are innovations recognized by musicologists. Didgeridoo design innovation started in the late 20th century using non-traditional materials and non-traditional shapes. The design changes include features that are similar to more familiar musical instruments like the trombone and natural horn.

The modern didgeridoo design innovations differ from traditional authentic digeridoos because they are not made by Indigenous Australians in a traditional style and do not use eucalyptus branches hollowed by termites. Some didgeridoo design innovations, like the sliding didgeridoos, are also multi-tonal, unlike monotonal traditional didgeridoos. Like traditional didgeridoos, modern didgeridoo innovations produce a drone sound and are classified as aerophones.

The sliding didgeridoo, or didgiphone, uses a telescopic mechanism to create a variable pitch instrument, and can be made from plastic, aluminium or wood.

Invented by didgeridoo player Charlie McMahon, the Didjeribone design is a cross between the didgeridoo and trombone, and consists of two plastic tubes placed inside the other. The sliding inner tube creates nine different tones, similar to the trombone mechanism. This enables the pitch to be varied mid-song, unlike traditional didgeridoos. As a result of eliminating the monotonal aspects of traditional didgeridoos, the Didjeribone can be used in horn concertos. The Didjeribone has a pitch range from high G to low B. The length is 65" extended, and 37.5" closed. The flared end also gives a brighter and louder sound.
