Mechanical songs like "3 Blind Mice" and "Row, Row, Row Your Boat" have been enjoyed for centuries. But mechanical songs can be more than just novelties for children. The songs in each of these sets are called "machines." Machines often use a different ostinato (repeating pattern) in each of the voices. Machines can have a transfixing beauty to them. Like a kaleidoscope, the repeating voices juxtaposed in new ways can be fascinating. The songs in this set - Set 2 - are special. Each song contains a hidden famous melody that reveals itself after the song gets underway. These songs are fun for the performers and fun for the audience. Full of ostinati and countermelodies, these well-crafted songs were written for adult ensembles but are appropriate for thinkers of all ages.
