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

  • an interview, guest essay, or other larger feature;

  • a smaller rotating feature like annotations, which samples non-standard notation in the spirit of John Cage & Alison Knowles’ Notations and Theresa Sauer’s Notations 21; and

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

Please feel free to contact the newsletter, even just to chat about music, at harmonicseries21@gmail.com. Feedback is welcome.

If you’re as tickled as we are about what’s in this newsletter, please consider sharing it with others.
