harmonic series is a free, monthly newsletter focused on experimental music, especially at the interfaces of jazz and classical and noise. Each issue is intended to include:

  • an interview, editorial, or other feature;

  • samples of graphic or other non-traditional notation with context and a preference for recent work with recorded examples, in the spirit of John Cage & Alison Knowles’ Notations and Theresa Sauer’s Notations 21; and

  • reviews, unrated and unranked, with an emphasis on recently released recordings of music.

The format borrows from the excellent Tone Glow. harmonic series is currently a project of Keith Prosk alone; please feel free to contact them at harmonicseries21@gmail.com.
