The Xenharmonic Alliance II (the most active group and a good one for beginners)
"For musicians and enthusiasts of music of the microtonal variety - for the notes between the cracks of the piano - for the Emancipation of Pitch - for those who dream in something besides the same twelve colors again and again... This is the group for all questionable intonational practices, be it 47-limit JI, eikosany, the Bohlen-Pierce scale, the subharmonic series, or good ol' 17-equal divisions of the octave..."
The Xenharmonic Alliance - Old Archives
The original XA group, unfortunately broken since 2012. DO NOT join this group. No new posts here, but some interesting older posts.
The Xenharmonic Alliance - Mathematical Theory
"This group is a sister of the main Xenharmonic Alliance group. We created this to have a place to talk about mathematical music theory without bombarding the main group with our (often esoteric) conversation. Unlike the main group, this group is smaller and much more focused on specifically the mathematics of music theory..."
Microtonal Music and Theory. (the largest group)
"Anything to do with microtonal music and theory."
Microtonal Music and Theory (a different group, note the lack of a period)
"A censorship-free forum for sharing and discussing anything relevant to alternative musical tuning systems and music created with them."
"Microtonal Projects is a not-for profit organisation dedicated to promoting microtonal music."
Out Of Tune Radio
"With few microtonal groups out there, this group was created in order to share microtonal music with people outside microtonal communities. Its a small step so microtonal composers/performers can get more exposure. So feel free post as much works as you want in any genre. It can be in any tuning or it can be your grandmas out of tune old piano!
RULES: NO TUNING DISCUSSIONS, NO THEORY, NO MATH, LEAVE INSULTS FOR YOUR WALLS AND PMs"
UnTwelve (Chicago area)
"Uno spazio dove scambiare informazioni al riguardo dei sistemi di accordatura alternativi al consueto sistema in uso in Occidente."
Alternative Musical Notation Systems
"This is a place to discuss Alternative Musical Notation systems
and other creative and fun musical ideas. Special emphasis given to microtonal notation. Membership is open to anyone with an active facebook profile.
Erv Wilson Discussion Group
"This group is here for people to discuss all of Erv Wilson's work."
Just Intonation Network
(for just intonation as opposed to temperaments or EDOs)
Small Equal Xenharmonic Temperaments
"This group is for musicians and composers working in equal temperaments other than 12-tone equal temperament, especially those with 24 notes per octave or fewer (though those working in ETs not too much larger are also welcome)."
"A working group to explore 22-tone equal temperament and related scales and temperaments. Open to all with an interest in 22 tones!"
"A working group to explore 31-tone equal temperament and related scales and temperaments. Open to all with an interest in 31 tones!"
Xenrhythmic Alliance (rhythm theory, not tuning theory)
"A group dedicated to the exploration and study of complex rhythmic ideas including but not limited to fractional time signatures, rhythm progressions, polyrhythms, microrhythm, and polytempo."
Composers Capable of Complicated Rhythms (rhythm theory, not tuning theory)
"This site is about sharing your own works of advanced rhythmic structures, or someone else's work. The point is to share, as well as to appreciate rhythmic sophistication."
Xenwiki Work Group
"This group is for discussion of matters related to the xenharmonic wiki,
, including terminology, article content and format, wiki organization and cleanup, and open projects."
Harmonic Series Study Group
"In this Group we study the Natural Harmonic Series of Ascending and Descending Harmonics (Overtones & Undertones) and their Combinations, exactly as they appear IN NUMERICAL FORM only.
Please post only ratios, whole (rational, integer) numbers, exponents and combinations of these. Thank you for understanding.
No cents, no “note” names, no tempered musical entities and sonic spaces (“intervals”), no staff notation, no 7-white/5-black piano keyboard and no other similar accidents of history and culture. And no “octave equivalence”...
Science, mysticism, quacademic fallacy, spiritual crap, accredited research, ancient mysteries, mainstream studies, forgotten/hidden knowledge, pseudo-science & numerology are all accepted for scholar purposes − as long as they do not insult intelligence and common sense in rampant ridiculous ways."
XA - Monthly tunings
"This group is meant to be a collaborative workgroup where we vote on a tuning and then work it out together. Share what you find! Harmony, chord progressions, melodies, counterpoint, etc. Soft synths, DAWs, hardware, interfaces, etc."
17 Tone Theory and Pedagogy
"A group focused on the exploration and study and documentation o
n a 17 Tone Equal Temperament or Well Temperament. Emphasis on studying 17 and as a result creating teaching and learning materials for others. Sharing compositions intended to expand our understanding of the tuning and documenting such research with an emphasis to build on knowledge and grow in this tuning system.

was developed by people here.
Yahoo MakeMicroMusic list
- Another outgrowth of [tuning], in the direction of, let's hear some music! The emphasis is on sharing original microtonal music, which sometimes unfortunately devolves into endless tech-talk.
