BEYOND TINY TIM When Kate Yoder, executive director of the Concord Conservatory of Music, sings — or, more accurately, strums — the praises of the ukulele, she is not just dutifully promoting her organization’s newest program. She is speaking as a recent convert herself — and one of the very first students to sign up for the conservatory’s inaugural ukulele course last fall.

“So many people will tell you they have ukuleles at home on a closet shelf,” Yoder said. “It’s not an intimidating instrument to learn. It’s easy and social; it’s fun to play in a group.”

And it’s not just throwbacks to the ’60s or Hawaiian folk singers exploring the possibilities of the ukulele, either. Pop singers including Eddie Vedder and LP have devoted entire albums to the instrument, Yoder noted. Chaim Burstein, a guitar teacher at the conservatory, offered to teach the course. Last fall’s class attracted 14 adults, ranging from their 30s to their 60s.

Yoder, whose primary instrument is the saxophone, was surprised by how much music theory the class covered. “We learned chord progressions,” she said. “We learned to play songs by Taylor Swift, the Beatles, Stevie Wonder.”

The conservatory is offering another beginner’s ukulele group starting this week as well as an intermediate session, both taught by Burstein. The new class begins this Tuesday and is open to students age 14 and up. Tuition for the 14-week session is $198. CCM is located at 1317 Main St., West Concord.
