They went through everything in our luggage after we arrived. Goldberg is speaking about her experience at the RSA security conference in San Francisco today. There were some real songs in my music. You wouldn't know what to do if you weren't a musician. They went through the whole thing one page at a time.

Goldberg says that the code worked and the Soviets didn't seize their music, but they did question all four travelers about what they were going to do. Goldberg is a music education professor at California State University, San Marcos.

Musical note names span the letters A to G so they don't give a full alphabet of options. The code was created by assigning the letters of the alphabet to the notes in the 12-tone scale. Goldberg wrote only in the treble clef in some instances. She added a bass clef and expanded the register to be able to play more music. Verisimilitude to her music was added by these details and variations.

When writing numbers, Goldberg would write them between the staves. She added other characteristics of composition, like rhythms and key signatures. Some doubled as code supplements to the letters hidden in the music notes to make the music look more legit. Sometimes she drew diagrams to remind herself of where to go for a meeting or how to deliver a package.

The code would have sounded more like a cat walking across piano keys if someone had played it as music.

I started by picking a note and then created the alphabet from there. It's fairly easy to write things once you know it. Goldberg taught his friends the code. We used it to get people's addresses and other information. Wecoded things while we were there so that we could take out information about people's efforts to emigrate and help other people leave.

After arriving in Moscow, the US musicians headed to Georgia. They met members of the Phantom Orchestra, many of whom spoke some English, and spent time getting to know each other, playing music together, and staging small, impromptu concerts in Yerevan.
