Stanley Jordan's "Haydn Seek"

This is a scatter-plot rendering from @stanleyjordanofficial is his lost computer music masterwork from his undergraduate days at @princeton, circa 1980. In the latest edition of “Composers & Computers," Jordan talks about how he recreated the piece for this podcast.
“Haydn Seek was a composition I made in 1980 while I was studying computer music at Princeton,” Jordan wrote. “It was spawned from an assignment in a composition class with J.K. Randall, in which we were to take an existing piece of music and compose a new one using something that we liked in the original. I based mine on a piano sonata in A major by F.J. Haydn. I was also studying computer music with Paul Lansky and I decided to make my composition for computer. This was an exciting time because computers were just beginning to be used as musical instruments. At that time computer music was only available at academic institutions and most of the music was very abstract. I loved that stuff, but I was more interested in bringing something new to traditional forms (think “Switched on Bach”)… I loved how Haydn got so much material out of a few simple patterns. In ‘Haydn Seek’ I take Haydn’s original themes from movement 1 and I expanded on them in my own way using more contemporary harmonies. Everything up until measure 28 is a condensation of Haydn’s main themes, taken exactly as Haydn composed them. Then, starting in measure 28, I begin to combine it with new material. The new material gradually grows and expands until the finale is completely my own, but still related to Haydn’s original main theme. The original version of Haydn Seek was incomplete and the materials were lost, so I recreated it here from memory and completed it using only compositional techniques and harmonic knowledge that I had at the time.” Hear the new podcast episode at this link: engineering.princeton.edu/new...
