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.diegojavierfares.com/quick-find-Catalina-Black-Sugar-Skull-Masquerade-Mask-with-Red-Flowers-mega-find/
