A record crowd attended the festival, which is now in its fourth year.

Yarriambiack councillor and committee member Ray Kingston said the crowd was gently building from year to year.

"This would have to be our best crowd yet," he said.

The predominantly acoustic and unamplified event gives people the opportunity to show off their musical and spoken-word talents in a variety of locations in the town.

About 15 performers lined up to play throughout the day.

Locations included a church, kindergarten, halls and even a verandah.

Cr Kingston said the kindergarten was a new venue this year.

"It provided a great space for families and a really nice atmosphere," he said.

"The festival is about everyone having a go in a relaxed space - it was a great day."

The event was free and performers volunteered their time.

Cr Kingston said it was pleasing to see it grow each year.

"It is the sort of thing that takes a few motivated people to put on each year," he said.

"We are now building a scenario where people are looking forward to it from year to year - it is slowly becoming part of Rupanyup's calender."

Music styles varied and included country, blues and even Irish small pipes.

Rupanyup Major Events president Ash Teasdale said the idea for the festival was based on a quote by Australian author Tim Winton.

"In one of his novels he talked about any music that could be played on a verandah -  dirt music," he said.

"That's how the whole thing started off."

He said the festival was a good opportunity for people to share their music with an audience.
