Here's a sampler of instruments in the lute family found at a recent Hummin' and Strummin' session at the Bluffton Public Library. Six string guitars predominate, but you'll find them in various sizes as well as bass guitars, mandolins and ukuleles. Twelve player-singers were at this session, which repeats from 5:30-7:00 p.m. on Mondays when the library is open.
