I agree with Hal and Avie. As a solo instrument, it's no accident it was chosen to depict eeriness, numinosity, fear, sci-fi, psychosis, ghosts etc.. Orchestration evokes.

The reason it never took off as a virtuoso instrument is surely that, when played as a violin might, it comes out sugar-coated, sickly, sentimentalised. In those contexts it's like funeral-parlour kitsch, thickly flowered and steeped in embalming fluid.

I still want to hear 'Parade of the Charioteers' for didgeridoo ensemble.
