But it was the extraordinary sounds he could make from a guitar in classical and jazz genres that was another string to his bow - a gift he had no hesitation in passing on to the many students he taught.
Smith was born in Kaitaia and came to Rotorua in 1979 to work for the then Forest Research Institute doing social research into implications of forestry. He left the organisation in 1999.
He was the chairman of the Rotorua Civic Arts Trust, consultant in social research and health research ethics, acting chairman of the Wellington-based Health and Disability Multi-Region Ethics Committee and chairman of the Lakes District Health Board Research and Ethics Committee.
He was the co-founder of the Rotorua Music School, member of the Whakarewarewa and Glenholme school committees, chairman of the Rotorua Girls' High School Board of Trustees, president of the Rotorua Performing Arts and Competitions Society and Bay of Plenty Health Research Regional Ethics Committee chairman.
Mary Smith said her husband was a "tower of strength" for the family.
"He was an incredibly grounded person and we all had huge respect for him."
Former Rotorua mayor Grahame Hall said he was a man of integrity and always had the Rotorua community at heart.
"I had the utmost regard for him. He had outstanding skills, expertise and knowledge and made such an enormous contribution to Rotorua. He has always been prepared to share his considerable talents whenever he was available."
Friend and fellow musician Richard Anaru said Smith never had a bad word to say about anyone.
"He was a consummate lover of life. It is heart breaking. We grew to be really good friends over the years and he will be sorely missed."
