The influential head of Moray Council's music instruction service has resigned in protest at the local authority's tuition fees rising by 85%.
John Mustard said the increase - approved last month as part of a bid to balance the council's budget - would "deprive" many young people of a skill and pleasure.
He said he regretted having to make the decision.
Moray Council said it was sorry to see Mr Mustard leave.
The 85% increase will raise music tuition fees to £699 a year.
Councillors approved the increase on 23 January.
'So much damage'
Mr Mustard said in a statement: "I can confirm that I have resigned as head of Moray Council's music instruction service.
"The reason is simple: I cannot agree with the decision by the council to raise the cost of music lessons by 85% - to what will be the highest level in Scotland.
"In a low-wage economy such as Moray this will have the effect of depriving many young people of a valuable skill and pleasure for life.
"I regret this deeply, but I cannot be part of a decision that will do so much damage to a service I've built up to national acclaim over the last 30 years."
A Moray Council spokesman said: "We are sorry to see John Mustard leave, he has created a huge musical legacy in Moray.
"We wish him well for the future."
It was reported last year that only 10 of Scotland's 32 councils still provided free music tuition.
