In 1913, a composer named J.R. Shannon published a song titled "Good Old Denver Town," just one in a rash of Colorado-centric ditties that popped up on pianos in the early 1900s. Thanks to the CU-Boulder Music Library, 21st-century players can tune into the 150,000-plus treasure trove of titles written about D-town and beyond, plus a vast, timeless array of ragtime, Western and Ingram scores. Songs are accessible through the Digital Sheet Music Collection, an Internet database that's searchable by genre and title. Though the collection's primary mission is to preserve old-fashioned music from the player-piano days, the Digital Sheet Music Collection makes a great case for the beauty of life in the modern age.
