Abstract: Methods for generating music are disclosed. A music data file is generated at a first node. The music data file is transmitted from the first node and received at a second node. Musical definition data that provides information regarding a data structure and data for musical parameters is extracted from the music data file at the second node. The musical definition data is processed and music is generated at the second node for playback in accordance with the data structure and the musical parameters. A modified music data file is generated at the second node and transmitted to the first node. Modified music is generated at the first node based on the modified music data file.

Abstract: Systems and methods for creating, modifying, interacting with and playing music are provided, particularly systems and methods employing a top-down process, where the user is provided with a musical composition that may be modified and interacted with and played and/or stored (for later play). The system preferably is provided in a handheld form factor (860), and a graphical display is provided to display status information, graphical representations of musical lanes or components which preferably vary in shape as musical parameters and the like are changed for particular instruments or musical components such as a microphone input (845) or audio samples. In addition, the present invention makes use of node-based music generation as part of a system and method to broadcast and receive music data files, which are then used to generate and play music.
