Musical cryptography

Musical cryptography is the art of encoding messages within music, using specific musical elements—such as notes, rhythms, melodies, or harmony—to conceal information. Like a secret code, the message is hidden in the musical structure, making it unintelligible unless you understand the encryption method. This technique has historically been employed for clandestine communication or artistic expression, blending music theory with cryptographic principles. Essentially, it transforms music into a medium for secure or secret messaging, requiring specialized knowledge to decode and interpret the concealed information.
