Interactive music generation system making use of global feature control by non-musicians

A computer-implemented method for interactively generating music comprising the steps of:

• receiving from a user input device a position signal and at least one selection signal that are generated by the user input device in response to a user gesture that is manifested by manipulation of said user input device;
• displaying a graphic object;
• varying an appearance of said graphic object responsive to said position signal and said at least one selection signal, and continuing to vary the appearance of said graphic object after completion of the user gesture in a manner determined by the user gesture;
• and
• generating a musical segment having at least one global feature selected responsive to said monitored position signal and said monitored at least one selection signal, wherein said musical segment is isomorphically coherent with variation of appearance of said graphic object.

A computer-implemented method for interactively generating music comprising the steps of:

• a) receiving a first performance gesture from a first human performer via a first input device;
• b) receiving a second performance gesture from a second human performer via a second input device;
• c) varying an appearance of one or more graphic objects in a visual display space responsive to said first performance gesture and said second performance gesture;
• and
• d) generating a musical segment with one or more global features specified in response to said first performance gesture and said second performance gesture.
