In 2015 Aidin Ardjomandi won A’DESIGN Award by inventing a new brand musical instrument, the Celloridoo, which was a hybrid one by a combination of Cello and the Didgeridoo. The Aerophone part of Celloridoo is played with continuously vibrating lips to produce the drone while using a special breathing technique called circular breathing. 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. A chordophone needs a Pegbox, a neck and a resonance box, and an aerophone needs a pipe and a mouthpiece so the pipe under the mouthpiece became to peg box and neck to install finger board on it, and the lowest part of it became to a resonance box to install bridges, holes and keep the strings.
