How a Saxophonist Tricked the KGB by Encrypting Strategies in Audio

“When we arrived, we were instantly pulled aside, and they went by anything in our baggage, to the position of unwrapping Tampax. It was crazy,” suggests Goldberg, who is presenting about the expertise and her musical code at the RSA security meeting in San Francisco currently. “With my songs, they opened it up and there were some true tunes in there. If you are not a musician, you wouldn’t know what’s what. They went site by webpage by everything—and then they handed it back.”

Goldberg suggests that while the code labored and Soviet officers did not confiscate their music, they did interrogate all 4 travelers about what they prepared to do though in the USSR. “We ended up brought into a space with a large burly guy who banged on the desk and yelled at us,” remembers Goldberg, now a new music education professor at California State College, San Marcos.

Musical observe names span the letters A to G, so they really don’t deliver a complete alphabet of possibilities on their have. To create the code, Goldberg assigned letters of the alphabet to notes in the chromatic scale, a 12-tone scale that involves semi-tones (sharps and flats) to increase the prospects. In some examples, Goldberg wrote only in a single musical assortment, recognized as treble clef. In other folks, she expanded the sign-up to be capable to encode much more letters and additional a bass clef to increase the variety of the musical scale. These particulars and variants also extra verisimilitude to her encoded songs. 

For quantities, Goldberg would merely produce them concerning the staves, where from time to time you may see chord symbols. She also extra other features of composition, like rhythms (fifty percent notes, quarter notes, eighth notes, whole notes), important signatures, tempo markings, and articulation indicators like slurs and ties. Most of these were there to make the new music search a lot more authentic, but some doubled as coded nutritional supplements to the letters hidden in the music notes. She even once in a while drew small diagrams that could be mistaken for charts to remind herself of wherever a meeting location was positioned or how to provide a little something. 

Even though anyone could technically have played the code as audio, it would have sounded significantly less like a tune and far more like a cat strolling across piano keys.

“I picked a note to start out, and then I designed the alphabet from there. When you know it, it ends up staying fairly quick to compose points. I taught my friends on the journey the code, as well,” Goldberg claims. “We made use of it in purchase to choose in people’s addresses and other information and facts we would will need to come across them. And we coded points although we were there so we would be in a position to choose out some details about folks and their endeavours to emigrate, as nicely as facts we hoped could assist other persons talk to to leave.”

The US musicians bought their bearings in Moscow prior to heading to Tbilisi, the capital of Georgia. There and on their up coming quit in Yerevan, the money of Armenia, they effectively fulfilled users of the Phantom Orchestra, many of whom spoke some English, and expended time obtaining to know each and every other, playing audio collectively, and even staging smaller, impromptu live shows.
