A music production system is presented that includes a music module to access computer software applications and produce music compositions. The system in a first mode records and corrects the pitch of a tune, typically a tune sung by a user at a microphone. The user may produce additional tracks with the software applications including instruments playing the recorded and corrected tune or to accompany the user while singing the tune. In a second mode, the system generates virtual characters such as band members, a producer and/or a manager to simulate the production and presentation of the recorded tune as a stage show as part of a recording industry. Virtual characters may assist in the use of user interface functions during music composition development and orchestration.
