The folks at Swallow Hill Music, which celebrates its fortieth anniversary this year, cannot get enough of the ukulele. For the past decade, they've hosted Denver Ukefest, a three-day festival showcasing all things uke, including workshops, master classes and performances from some of the country's top players. While the annual shindig is a top-notch gathering of uke players, Swallow Hill's music program celebrates the instrument year-round, with classes and workshops that teach everything from basic chords to improvisation. On the third and fifth Saturdays of every month, Swallow Hill also hosts Denver Uke Community, a gathering open to all levels of players.
