Abstract: The present invention provides a device, method and system for the visualization of stringed instrument playing. The invention involves measuring a property of one or more strings, and using the property to create or modify a visual display. In one aspect of the invention, a change is measured in a property of a portion of a string of a stringed instrument and a signal is generated in response to the change. The signal can then be used to modify or create a visual display. In another aspect of the invention, a change in a property of each string on a stringed instrument is measured and signals are generated for each change. These signals may be low level signals that are processed to generate one or more high level signals providing, e.g., an overview of how the instrument is being played. The high level signals, low level signals, or both may be used to modify or create a display.
