Abstract
The invention provides an electronic method for assessing student skills on a stringed musical instrument, based on comparing the digital signature of an expert template sound to the digital signature of a student's attempt to replicate the template on the stringed instrument. In particular the method employs in sequential series an audio input device, an analog-to-digital converter, an audio correlation decoder, a digital-to-analog converter, and an audio output device; in certain embodiments they are all under the control of the same central control processor, which also has access to a first addressable data memory including unprocessed emulations from a student, a logic filter circuit element, a second addressable data memory including emulations from the student that have been filtered to remove background noise and other extraneous elements, and an addressable data memory including expert templates for incremental components of stringed musical performance.
