''It's really exciting because he had been really working hard to get it to festivals and he was able to hear that it was, that it's going in that direction,'' Ms Anderson said.
Mr Knotts leave behind his wife Jackie, a strong supporter for her husband's project.
In a previous article Mr Knotts said he decided that the lyre should have a distinctly New Zealand flavour and has used New Zealand redwood for the frame and paua, pounamu (green stone) and oyster shell for the decoration.
Mr Knotts made no attempt to hide the fact that he is "virtually terminal but still managing". His failing health meant it was even a strain to string the lyre after a harpist advised him to make a new bridge to improve its sound.
He has donated the $35,000 lyre to the Incubator at the Historic Village. "Without their support, it would never have got to this stage,'' Mr Knotts said.
