A system, and related method, for creating music in real time includes an input device and a real-time music generator. The input device is used by a user to provide rhythm-related signals and pitch-related signals to the real-time music generator. The real time music generator receives the rhythm-related and pitch-related signals and creates or composes in real time music that includes pitches based on the pitch-related signals and rhythmic activity based on the rhythm-related signals. The input device can provide pitch related and rhythm-related signals that are representative of position, velocity, or acceleration. The real-time music generator can derive position, velocity, or acceleration from the pitch-related and rhythm-related signals and compose in real time music comprising pitches and rhythm activity based on the derived information. The input device can be, for example, a contactless sensor such as an infrared transceiver or a digital camera, a joystick, a mouse, a...

26. The system of claim 1 wherein the input device comprises a discrete controller.

27. The system of claim 1 wherein the real-time music generator includes an accumulator that receives the rhythm-related signals from the input device and accumulates them over a predetermined period of time, and the real-time music generator composes in real time music comprising rhythmic activity based on the accumulated rhythm-related signals.

28. The system of claim 1 wherein the real-time music generator includes a pattern matcher that receives the rhythm-related signals from the input device and selects one of a plurality of rhythm fragments that corresponds to the rhythm-related signals, and the real-time music generator composes in real time music comprising rhythmic activity based on the selected rhythm fragment.

29. The system of claim 1 wherein the first axis and the second axis comprise the same axis.
