UnTwelve has just launched a brand-new experimental discussion mailing list! Hopefully, we can generate some interest and at least a small community of people who want to discuss all things tuning-related, xenharmonics, musical practice, etc., in an old-skool mailing-list way. A nice alternative to the Facebook paradigm, anyway, for those that want such a thing. Searchable, too!

Happy New Year everyone! It's been a while since there has been news, but there are some cool things brewing in the background, nonetheless. One of these is of course the next iteration of our summer Xenharmonic Convergence Camp. You can check out the details here. Update: We may be adjusting our summer plans in light of the world situation. Look for a further update in early May.

Our board member Chris Vaisvil has a page of student piano compositions in various tunings up. The pieces are designed to give anyone with modest piano skills and a MIDI keyboard capable of being retuned an opportunity to try out various non-12 tunings, and perhaps to be inspired to write their own pieces as well!

The 2018 International Composition Competition rules have been posted! We expect to start taking submissions within the next few days. We are excited to see what the next crop of excellent compositions will look like! This year, the theme is Béla Bartók-inspired microtonal pedagogy, ala Mikrokosmos.

We are happy to announce the arrival of a new board member, Robin Meiksins, who was approved unanimously by the current board, at the beginning of March, to join our efforts. Robin is an outstanding flutist in Chicago, and an active member of the contemporary music scene. She will be performing some solo and wind ensemble UnTwelve-commissioned microtonal works at a concert in Chicago in September of 2018. Her presence and efforts will surely help us grow and attract new interest. Welcome aboard, Robin! We are also sad to see the departure of Clem Fortuna from our board. Clem leaves due to pressing personal and professional commitments, and has been a highly valued member, due to his vast knowledge and highly visible activity on the microtonal scene for several decades. Clem will be most missed, but will surely be still engaged, but in a lower profile. Best wishes and many thanks for your work, Clem!

We are please to announce a call for scores for a September 2018 concert in Chicago. The instrumentation is: flute, clarinet, bassoon, and trombone. Electronics are welcome, as is the composer appearing in their own work. This call is open to composers of any background, age, or nationality, but will prioritize works from composers who are women, non-binary, genderqueer, gender-non-conforming, or agender. You can submit for this event at our Google docs page for the call.

Mission Statement

The dimension of pitch in music (how high or low a certain musical sound is) remains largely tied to a standardized set of 12 notes. This is akin to a painter being stuck with only 12 standard colors.

UnTwelve is dedicated to exploring the current and historical frontiers of music beyond the 12-equal note tuning system. Our mission and vision is to commission and perform musical works which display the excitement and beauty of this frontier to both audiences and musicians.

In addition, we seek to set up musical education programs that highlight the wide-open expressive possibilities of such systems, and to promote and foster their usage by the current and next generation of musicians and composers.
