Zeisberg 18 “Eagle Dance Song”
It is likely that Zeisberg is entirely responsible for the harmonization and arrangement. If one compares the "First Impression of Eagle Dance Song" with the more fully harmonized and arranged version, I believe we have evidence here that Zeisberg heard a live performance, transcribed the melody he heard, then later harmonized and arranged the tune for piano. Zeisberg was clearly interested in adapting Indigenous materials to the piano, but it remains unclear to what ends.
