Coordinating and mixing vocals captured from geographically distributed performers

A system comprising:

• geographically-distributed portable computing devices for capture of media content for a coordinated group performance that includes at least vocal performance contributions captured at the respective portable computing devices, the portable computing devices each having a display, a microphone interface and a communications interface;
• the communications interface of at least a first one of the portable computing devices configured to receive (i) a backing track including a vocal performance of at least one other vocalist captured at a different, remote one of the geographically-distributed portable computing devices and (ii) a vocal score temporally synchronizable with the received backing track and with lyrics, wherein the vocal score encodes a sequence of notes for at least a portion of a vocal melody;
• the first portable computing device further configured (i) to render the received backing track and to concurrently present, in temporal correspondence therewith, corresponding portions of the lyrics on the display thereof and (ii) to, against the rendered backing track, capture and pitch correct at least a portion of a vocal performance of the user in accord with the vocal score;
• and
• a content service platform configured to stream, as the coordinated group performance, a mix of the user's captured vocal performance with the vocal performance of the at least one other vocalist captured at the remote portable computing device, wherein metadata associated with the streamed mix includes geocoded location of the respective vocal performance captures for display in association with an audiovisual rendering of the coordinated group performance.
