Have you always wanted to turn the rules of harmony on their head and hear—or even create—sounds you’ve never heard before? Then the Campus#28 “Untwelving” weekend workshop is just the thing for you. Learn to sing in two-part harmony with Anna-Maria Hefele, or grab an isomorphic controller, turn a knob, and transform familiar diatonic territory into strange soundscapes.

Campus#28 takes place as part of the so-called EDO Convention “Untwelving”, featuring many events at the Werkraum and habibi Kiosk at the Münchner Kammerspiele, as well as at the Fat Cat. The festival is dedicated to one of the most exciting musical developments of our time: the dissolution of traditional twelve-tone tuning (12-EDO) in favor of diverse microtonal systems, so-called Equal Divisions of the Octave (EDO), and other xenharmonic approaches—in short, a joyful “Untwelving,” a de-twelving of many musical genres.

Program
22.5., 5 pm | Meeting point at Habibi Kiosk, Maximilianstrasse

Introduction and tour of the exhibition of microtonal instruments

22.5., 7 pm | dinner together at the theater cafeteria
22.5., 8 pm | Concert „Untwelving: Beyond 12“, Habibi Kiosk
23.5., 3 pm | Meeting point at Habibi Kiosk, Maximilianstrasse
23.5., 3 – 7 pm | Workshop 1 „Obertongesang –Die Stimme als mehrstimmiges Resonanzinstrument“ with Anna-Maria Hefele

Can a person sing in two voices at once? Overtone singing makes exactly that audible: through deliberate sound shaping, individual overtones emerge from the voice, opening up new sonic spaces.

In this workshop, singer and overtone singer Anna-Maria Hefele offers an introduction to this fascinating vocal technique. Participants will learn to perceive overtones in their own voices and make them audible. This cultivates a keen sense of timbre, resonance, and intonation—and provides direct access to one’s own voice. The workshop is open to all singing enthusiasts—from curious beginners to professional musicians. No prior experience is required.

23.5., 3 – 7 pm | Workshop 2 „Touch the Microtones – PitchGrid meets PolyChromatic Music“ with Peter Jung & Dolores Catherino

What happens when melody and harmony are viewed as complementary yin and yang? In this joint workshop, Peter Jung and Dolores Catherino explore the two-dimensional structure of tonal music and its polychromatic extension.
Peter will demonstrate how the PitchGrid reveals the hidden two-dimensional structure behind the diatonic scale and generalises this into structurally coherent MOS scales and EDOs – real scales with real modes, real chords and real key changes that turn conventional harmonic rules on their head. You will explore this space using isomorphic controllers, viewing the diatonic scale as a point on a map, discovering how individual tunings contain multiple complete musical worlds within them, and using inverted tunings to make exotic scales suddenly sound familiar and harmonious.
Dolores Catherino, a pioneer of PolyChromatic Music, uses colour as a direct perceptual tool to illustrate microtonal pitch relationships and expand our auditory awareness far beyond the boundaries of the twelve-tone system. In this workshop, you’ll have the opportunity to explore playing continuous and isomorphic controllers live.

No prior knowledge required. Whether you’re an experienced microtonalist or just curious about what lies beyond the 12 tones—come by, play along, ask questions, and take a piece of the microtonal map home with you.

23.5., 7:30 pm | Concert „Untwelving: The Xenharmonic Space“, Werkraum
