The algorithm presented in this paper provides the means for the real-time recognition of the key signature associated with a given piece of music. based on the analysis of a very small number of initial notes. The algorithm can easily be implemented in electronic musical instruments. enabling real-time generation of musical notation. https://www.roneverhart.com/Dell-S2422HZ-23-8-FHD-IPS-Video-Conferencing-Monitor-AMD-FreeSync-4ms-GtG-16-9-Anti-glare-Height-Pivot-Swivel-Tilt-US/
