Over a century ago, Boris Sabaneyev wrote a Canzona Phrygia, a mostly polyphonic bit of music for organ and arranged for piano. The first ten bars of the middle and upper contraputal voices serve as the basis for the music below. The oddly-tied quarter notes in bars 6 and 7, as well as the stray rests in bar 8, are the result of the composer not quite understanding how Dorico, the notation software, works yet.
The recording was realized by the Steinberg Dorico Piano played by I. MacApel.
