The banjo break at the beginning comes almost directly from Pete Seeger’s How to Play the 5-String Banjo. I worked out the banjo part in the verse by ear, following the melody and drawing inspiration from Buell Kazee’s recording on the Anthology of American Folk Music.
The electronics part uses multiple looping delays to create a rhythmic texture from the banjo. The timing for each delay line is based on the time between consecutive instances of a given note played by the banjo. One delay line changes every time the computer hears the note g , another changes when the computer hears f, another for b-flat, etc.
The tablature above more accurately represents how I’d play the tune on a fretted banjo. When I play the fretless banjo, as on the recording, I throw in more slides on the 3rd and 4th strings.
