Mixing Console and LaptopWe are constantly surrounded by music in our everyday lives, and as technology has progressed, it's become even more prevalent. But what if this music could be used as more than just a form of entertainment? For centuries, authors, composers, and scientists have been experimenting with the possibility of musical cryptography and steganography. In this episode, we explore different methods of encrypting and hiding messages in music, the history of the practice, and how musical cryptography affects how we analyze music from the past and how we could produce music in the future.
