Baadsvik about the piece: Did You Do? is a word-play on ‘didgeridoo’, the name of an instrument which is one of the oldest in the world, possibly developed around 1,500 years ago. It is basically a wooden tube (which is of course the meaning of the Latin word tuba) and is played in a similar way to my instrument, i.e. by vibrating, or ‘buzzing’, the lips into the mouthpiece. During a visit to Australia I therefore bought a didgeridoo to try it out. The difficult part wasn’t playing it but finding music that could be played with others, which is why I composed this piece for didgeridoo and wind band. As the instrument only has a single, more or less fixed pitch, the whole composition is centred around D flat.
