Contributions
Wolk introduced Train Jazz by saying he gave every New York train an instrument. The app turns the live map into a jazz ensemble. Its current published client assigns line groups roles such as bass, comping, solo and color, with register limits and voice-leading. Closely grouped trains can share a held note or voicing. The version notes explain the progression from raw oscillators through sampled instruments to role-based musical behavior. The mapping produces a composed interpretation of train activity rather than an audio recording of the subway.[3][5][6]
