Hobbs, a self-taught banjo player and bluegrass lover who helped spearhead the jam sessions with the mayor, said there are plenty of times someone starts playing a song he doesn't know.
"There are chord progressions that you follow, but sometimes you just have to go with it," he said.
For some musicians, the Tuesday jam is the perfect place to brush up on their skills.
"It's a great opportunity for people to learn. If you have a question, just pull someone aside and they'll be happy to help you out," said Charleston resident and banjo picker Joe Hunter.
Novice musicians can sit in the front row during the performance with their instruments and follow along with the tunes, something Hunter said makes the show unique.
"It's not just a performance, it's interactive," he said. "It gives you something to do, and you're all the time learning and improving."
Although the group is open to all levels of musicians, Hobbs said the idea of having to jump into a tune that a player is not familiar with in front of a crowd could be intimidating.
"But I just tell people that if they make a mistake, just look at the guy next to you," he said with a laugh. "No one will know."
Kelsey Stover, 21, and her grandparents, Jim and Jeanne Perdue, came all the way from Clay County for the first time this past Tuesday to sing.
Stover, who has been singing gospel music with her grandparents since she was 3, said she was happy for the experience and the warm reception they received.
"I would come again," she said, hoping that having a young singer among the performers would encourage more people her age to come out and experience the music.
Robin Campbell, recreation director for Belle, said MusicFest has had an untold impact on the community.
"It gets people out of their homes," she said. "We have kids as young as 3 [and] all the way up to seniors that come out and play."
"It's a laid-back atmosphere," Hobbs said. "We're like one extended family."
The town knows it's unique in offering free live music on a weekly basis, but that is just the start. It plans to offer ballroom dancing classes, as well as a gospel sing, the third Saturday of each month.
"Believe me," Asbury said, "this is just the beginning."
And a good beginning it is.
"My motive for this thing," Hunter said, "is to just get together and enjoy some West Virginia music."
