A good session player is hard to find, but u jam is always ready to rock. The Web app doubles as a studio band and a recording studio. It analyzes a melody and then produces sophis ticated harmonies, bass lines, drum tracks, horn parts, and more. Before ujam's Al can lay down accompaniment, it must figure out which notes the user is singing or play ing. Once it recognizes them, the algorithm searches for chords to match the tune, using a mix of statistical techniques and hardwired musical rules. The stats are part of the software's AI and can generate myriad chord progressions. The rules-based module then uses its knowledge of Western musical tropes to narrow the chord options to a single selection.
