A veritable museum of acoustic instruments, the Denver Folklore Center is stocked with used and vintage banjos, mandolins, dulcimers, autoharps and guitars from floor to ceiling; it's a sight to make the city's string players sing. A new generation of players can also find inspiration among the itty-bitty things for every skill level and hand size: whistles, tambourines, flutes, recorders and authentic Hawaiian ukuleles. There's also sheet music from around the world, instructional videos and CDs, stands and strings -- even those fancy harmonica neck-wrap thingies that really boost the average Dylan impression. Staffed by players, teachers and die-hard folk loyalists, the Folklore Center strikes the perfect chord.
