Our invention is an apparatus and method to identify and simultaneously visualize and hear musical notes contained in an analog or digital sound wave. Musical notes are expanded into a language for the eye as well as the ear. An analog-to-digital converter processes an analog sound wave to provide a digital sound wave. Component frequencies of the digital sound waves are identified, filtered and translated to their corresponding musical note and volume. As the original digital sound wave is sent through a digital-to-analog converter and output to an audio device, the identified musical notes are synchronously output to a display device. User-specified parameters, adjustable at any time before, during or after the music-playing process, control frequency filtering, the graphic display of the identified musical notes and the graphical background on which the musical notes are displayed. Users may also utilize existing, or create their own, computer programming code software modules, known as plug-ins, or hardware components, to interface with the invention to extend and control the invention's functionality. Because the synchronous musical note identification and visualization process occurs extremely quickly, the method applies and works in real-time for live music.
