Music Sheet Cipher

Encryption uses 14 notes and eighth notes, quarter notes, half note and whole note, this is 4*14=56 symbols + 3 extras. There are many ways to encode letters with these 59 symbols.

dCode try common combinations in an automatic way and allows you to tell your own character list.

Example: Example 1 : alphabet is composed of 14 eighth notes then the first 12 quarter notes : do₁ = A, re₁ = B, ... si₁ = G, do₂ = H, until sol₂ = N then quarter notes do₁ = O, etc. until fa₂ = Z.

Example: Example 2 : alphabet is composed of the first 13 eight notes then the 13 first quarter notes.

The decryption of the Musical Sheet Cipher consists in the substitution of the 59 symbols (notes) by the characters of a defined alphabet.

The ciphered message is composed of classical notes without musical value.

The notation used does not necessarily matter, no more than the instruments or actually produced sound.

The sheet can be printed without a key or other important detail for a musician.

Try multiple alphabets and think to use a shifting cipher.
