Abstract
Abstract A dynamic display for automatic sound signal analyzing equipment that displays the closest recognized musical note to that being played or sung by a musician, whether the note is sharp or flat or on tune and if sharp or flat, the extent to which it is sharp or flat by means of a strobe-like moving bar pattern.
