Modern didgeridoo designs

The design changes include features that are similar to more familiar musical instruments like the trombone and natural horn.

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

[7] Scott Dunbar independently created a version of the variable pitch didgeridoo instrument called the slide didge in the early 1990s.

The didgebox is monotonal and made in the specific keys C, D, and E. The Biking PVC Didgeridoo, also named as a Cyclophonica Didge and Bike Didge, was developed by the Cyclophonica Bicycle Orchestra, founded in 1999 in Rio de Janeiro- Brazil.

The construction method includes cutting the cylindrical parts, joining them with the connections and making a "mouthpiece" from the pipe end by heating it up and molding it to better adapt in the player's mouth.

The main interesting features are that it can be used while the player is cycling - with no accident risks to the audience or player- and that a trained performer is able to make circular breathing while doing the physical work required for biking with the Cyclophonica [8] The spiral didgeridoo is also known variously as a spiral didge, spiralidoo, didgehorn or snail didgeridoo.

[9] A keyed didgeridoo (having keys somewhat like those of a saxophone, allowing the performer to play melodically) was developed in the late 20th century by the U.S. didgeridoo player Graham Wiggins (stage name Dr. Didg) and used on his CDs Out of the Woods (1995) (in the track "Sun Tan") and Dust Devils (2002) (in the tracks "T'Boli" and "Sub-Aqua").

In 2015 Aidin Ardjomandi won A’DESIGN Award[11] by inventing a new brand musical instrument, the Celloridoo, which was a hybrid one by a combination of Cello and the Didgeridoo.

This requires breathing in through the nose whilst simultaneously expelling stored air out of the mouth using the tongue and cheeks and the chordophone part is played with a bow.
