Has any instrumental music ever been used to carry information?

  • Music is often dubbed 'the universal language', but language usually carries some information.

    I know that music has many different notes, with letters and pitches assigned to each. Was there ever any instrumental (lyric-free) music written as a code to carry information, in any form? (numbers, letters, etc)

    If so, can you please list the name, and artist/composer, if possible?

    Thanks for your help.

    While not an exact answer (and thus left as a comment), an old player-piano roll was the influence behind frequency-hopping.

    YYZ by Rush is a pretty obvious example.

    YYZ is the IATA airport identification code of Toronto Pearson International Airport, near Rush's hometown. The band was introduced to the rhythm as Alex Lifeson flew them into the airport. A VHF omnidirectional range system at the airport broadcasts the YYZ identifier code in Morse code. Peart said in interviews later that the rhythm stuck with them. Peart and Geddy Lee have both said "It's always a happy day when YYZ appears on our luggage tags."

    The pieces's introduction, played in a time signature of 10/8, repeatedly renders "Y-Y-Z" in Morse Code using various musical arrangements.

    "YYZ" rendered in Morse code:

    Y           Y           Z
    - . - -     - . - -     - - . .

    A think quite a few pieces have embedded the SOS (...---...) Morse code, but right now I can only think of one: Stranded in Iowa by Manfred Mann (https://www.youtube.com/watch?v=yi_5G_rKKTE)
