Music and its attributes have been used in cryptography from early days. Today music is vastly used in information hiding with the use of Steganography techniques. This paper proposes an alternative to steganography by designing an algorithm for the encryption of text message into music and its attributes. The proposed algorithm converts the plain text message into a musical piece by replacing the text characters of the message by mathematically generated musical notes. The sequence of musical notes generated for the particular character sequence of plain text message mimic a musical pattern. This musical pattern is sent to the receiver as a music file. The seed value for encryption/decryption key is sent using the asymmetric algorithm RSA, where the key maps the letters corresponding to a musical note. The encryption key used is an n x n matrix and it will be generated using the seed value for the key on both sender and receiver ends.
