Marc Sabat: keynote presentation A Compact Enharmonically Viable Subset of Harmonic Space. The Stern-Brocot Tree and Some Thoughts About Lattices and Spirals

Materials for this keynote have been prepared in by August 2020 by Thomas Nicholson and Marc Sabat and include a text by Catherine Lamb. The keynote is a conversation between Marc Sabat and Thomas Nicholson about the article and some open questions about finite sets tuned in extended JI.

Tenney Harmonic Space is a representation of rational intonation extending Euler’s lattice to potentially infinite dimensions. There are two embedded measures: the usual pitch-height distance, proportional to the logarithm of the ratio of two frequencies, and harmonic distance, measuring along the prime axes of harmonic space, determined by the absolute value exponents of the ratio’s prime factorisation. Since no ratios other than powers of 2 (unisons, octaves) multiply to produce another power of 2, no finite JI pitch set can replicate the same non-2 interval at every note. However, acoustic instruments and human hearing do allow a certain tolerance. The potential accuracy of pitch-height differentiation suggests that acoustic instruments ought to be able to tune notes to within about a schisma (2c) in critical harmonic contexts meant to be perceived as extended JI. Thus, some finite subsets of harmonic space may function as tolerably “complete” approximations of harmonic auditory cognition. In such cases, when combining intervals it is desirable to maintain “consistency”: ratios represented by best-case mistunings ought to combine to match best-case representations. Also, it is generally desirable to minimise the retuning of held notes in common-tone chord changes. These requirements cause adherents of adaptive JI and quasi-JI equal tempered divisions to investigate sets of pitches with extremely fine grain. This article proposes a different approach, one which, at least conceptually, offers a potential to be tuneable by ear, while opening a door to the viability of enharmonic exchange, allowing a continuous traversal of the space. By generating lowest terms rational numbers using the Stern-Brocot Tree up to order 9, transposing these ratios to each of the ratios of the Pythagorean pentatonic, merging, normalising and eliminating duplicates, a set of 933 pitches is proposed which brings together the various advantages of adaptive JI, fine-grain equal temperaments, and the unmediated sonic clarity and playability of rational intonation.

Canadian composer of Ukrainian descent Marc Sabat (*1965) has been based in Berlin since 1999. He makes pieces for concert and installation settings, drawing inspiration from ongoing research about the sounding and perception of Just Intonation. He relates his practice to various music forms — folk, experimental and classical. In collaborations with other musicians and artists he is seeking points of shared exploration and dialogue between different modes of experience and cultural traditions.

Largely self-taught as a composer, Sabat studied violin at the University of Toronto, at the Juilliard School in New York, and computer music at McGill University, as well as working privately with Malcolm Goldstein, James Tenney and Walter Zimmermann, among others. With Wolfgang von Schweinitz he has developed the Extended Helmholtz-Ellis JI Pitch Notation and is a pioneer of music written and performed in microtonal Just Intonation. In 2000, he co-founded the Plainsound Music Edition website, conceived as a curated, interdisciplinary virtual artists’ edition.

Sabat’s work is played internationally. He teaches composition and the theory and practice of intonation at the Universität der Künste Berlin. Together with colleagues Catherine Lamb and Rebecca Lane he formed the Harmonic Space Orchestra in 2019.

Klaus Lang: Keynote presentation dettifoss. birds.

Prof. Klaus Lang tells about the keynote subject as follows: “I will talk about how historic tuning systems mirror interpretations of the world and led to specific aesthetic programs that are combining systems of tuning and music theory and compositional practice and how i draw conclusions from this for my own work as composer who uses the choice of a specific tuningsystem as one musical parameter that can be used as a means of composition.”

Klaus Lang (*1971 Graz / Austria) lives in Steirisch Lassnitz (Austria). He studied composition and theory of music (with H.M. Preßl, B. Furrer and Y. Pagh-Paan) and organ. Klaus Lang loves tea and dislikes lawnmowers and Richard Wagner. Klaus Lang’s music is not a means to convey extramusical contents, such as emotions, philosophical or religious ideas, political propaganda, advertisement etc… His music is no language used to communicate non-musical content. Music is seen as a free and selfstanding acoustical object. In his work he is not using sound, sound is explored and given the opportunity to unfold its inherent rich beauties. Only when sound is just sound it is percievable as that what it really is: a temporal phenomenon – audible time. Klaus Lang sees time as the genuine material of a composer and at the same time also the fundamental content of music. In his view musical material is time perceived through sound, the object of music is the experience of time through listening. Music is time made audible.

Robert Hasegawa: ​”Composing with hybrid microtonalties” The history of microtonal music has largely been defined by the creation of closed and self-sufficient musical languages based on systematic derivations from axiomatic principles: for example, Harry Partch’s extended just intonation or Ivan Wyschnegradsky’s cyclical approach to microtonal equal temperaments. However, contemporary microtonal composers such as Manfred Stahnke and Georg Friedrich Haas often create hybrid microtonalities that combine apparently incompatible theories within a single musical work. Various strains of hybrid microtonality are explored through short analytical studies of the author’s own compositions, focused principally on the combination of principles of extended just intonation with various equal temperaments splitting the octave into twelve, nineteen, or twenty-four steps.

CV: ROBERT HASEGAWA is a composer and music theorist based in Montreal. His music explores a variety of microtonal concepts and techniques including just intonation, equal temperaments, hybrid systems, and frequency-based harmonies. Central topics of his research are spectral music, music perception and cognition, and the analysis of timbre and orchestration. He has been a faculty member at McGill University’s Schulich School of Music in Montreal since 2012.

Microtonal Projects: ‘The 19-division trumpet: exploring harmony ’

Microtonal Projects: Donald Bousted (Composer), Stephen Altoft (Trumpeter)

Stephen Altoft (19-div trumpet) (UK/DE) and Donald Bousted (composer) (UK) are joint Artistic Directors of Microtonal Projects which organised four UKMicroFests in London, and then established EUROMicroFest in 2013. As part of their project “The Microtonal Trumpet” they created affordable trumpet mechanisms which allow the temporary conversion of a standard trumpet into a microtonal instrument. They first discovered a practical solution for quarter-tones, then later for 19-divisions of the octave. This presentation charts the use of harmony in 19- division solo trumpet repertoire. You can find out more about “The Microtonal Trumpet” at http://www.microtonalprojects.com.

Stephen Altoft is dedicated to the creation of new repertoire for the trumpet. As a solo artist, and with percussionist Lee Ferguson as duo Contour, he has given concerts throughout Asia, Europe, the United States and Canada. He has appeared at the American Festival of Microtonal Music (New York), the New England Conservatory for the Boston Microtonal Society, the Daegu International Contemporary Music Festival (South Korea), “Mikrotöne: Small is beautiful” Symposium (Mozarteum, Salzburg), and EUROMicroFest (Freiburg, Germany). www.stephenaltoft.com
Donald has a PhD in musical composition from the University of Huddersfield where he worked for 8 years as a lecturer in composition (1992-2000). He was a Leverhulme Artist in Residence at the London Metropolitan University in 2000-1 and has also worked as a part-time lecturer at Kingston University. He has presented his music and projects at many UK university music departments including the Royal College of Music and the Royal Academy of Music, in America at LA MicroFest, in South Korea, in Austria at ‘Mikrotöne- Small is beautiful’ Symposium 2017, at the Koninklijk Conservatorium Brussel and in Germany at the Akademie der Tonkunst, Darmstadt and the Hochschule für Musik Freiburg. He often gives joint presentations, with Stephen Altoft, on the microtonal trumpet. He is a joint author of The Microtonal Recorder Manual (Moeck, co-authored with Kathryn Bennetts and Peter Bowman).

Alessio Elia: “Polysystemism: a tool to shape music in connection with acoustical phenomena”

What’s more evanescent than sound? What is closest to immaterial among the manifestations of the perceptible realm if not music? Well, although this has always been noted, since the dawn of time, music in its historical path, has fallen into the error of becoming a language. It certainly reached peaks of inestimable beauty and depth of thought, but it gradually moved away from its ethereal essence and I would even say magical-alchemical dimension. During my career as a composer I have tried to trace it back to what I believe to be its most authentic origins and I have tried to organize the sound according to the ways in which we perceive it, making Berkeley’s expression my own according to which “being is being perceived”. In the search for a meaning of music as sensation I developed a compositional technique that I called polysystemism, that is, the simultaneous use of different tuning systems in order to create acoustic phenomena on which to base the aesthetics of my research and music. The present paper reports on the excursus of this almost twenty-year-old investigation, both through its musical works and by providing some practical solutions for the realization of its intents. In the final analysis, I believe in the effect of music on human thought and soul and to put it with Plato: if music changes, the most important institutions will also change. And so be it.

Alessio Elia is an Italian composer whose field of sound investigation is the search for a musical writing capable of combining acoustic phenomena with their sensorial perception. He has received commissions from major institutions, orchestras and ensembles on the international scene. His music is published by Universal Music Publishing EMB and released on CD by Warner Classics.

Petr Pařízek: “Applying Mathematical Knowledge to Performing Music In Practice”

This lecture focuses on the issue of using some mathematical knowledge about relationships between pitches to better understand the rules of intonation in a choir or in a chamber orchestra, primarily in the context of Baroque or Renaissance music or contemporary microtonal music. The information presented here can be useful for players/singers and for conductors as well. Some crucial differences between intonation styles are mentioned and the danger of possible conflicts of intonation requirements is discussed. Finally, some ideas are suggested for making the rules of proper intonation clear enough to the player so that he/she doesn’t need to write down dozens of additional marks for adjusting the tuning.
Petr Pařízek is currently a lecturer at the Janáček Academy of Music and Performing Arts in Brno, Czech Republic. Previously, he studied piano playing, flute playing, and composition. He has also been given harmony and composition lessons by the Czech composer and musicologist Daniel Forró. Both in his compositions and in his research, Pařízek specializes in things like alternative musical temperaments, non-standard harmonic systems, the relationships between timbres and scales, creative application of audio DSP effects, and linking harmonic and sonic elements in music. Much of his work deals with acoustic interference within specific temperaments, which partially overlaps with the issue of tuning in the context of Baroque or Renaissance music.

Edward Powell: “Microtonalism found in Arabic and Indian music”

This lecture gives an overview of how microtonalism is found in the music of the middle and far east, explained from a western perspective. Examples of microtonal musical expression found in ragas, makams, and “the Blues” (for comparison) are clearly demonstrated and explained.
Edward Powell is a cross-cultural performer, composer, instrument builder, and educator. Having spent more than a decade living and studying in the Orient with indigenous masters Edward’s music is now profoundly influenced by the Indian, and Middle-eastern modal traditions. Since 2000 Edward has self-released 7 albums of original music and hand-crafted more than 60 complex original instruments which he uses for performing and recording.
Edward has been a professional musician for more than 40 years, has performed in a wide variety of venues and festivals around the globe.

Christian Klinkenberg: “The Glacier – Combining microtonal scales”

Composition based on microtonal scales is enjoying increasing popularity. Xenharmonic composers have usually limited themselves to one scale. However, the combination of microtonal scales has so far remained mostly unexplored. In “Le Sacre du Printemps” Igor Strawinsky combined modes based on the western tuning system. This approach is called polytonality. It would seem likely that the different microtonal scales can also be combined in compositions. This results in a multiplication of compositional possibilities without slipping into confusion since the composer himself determines the framework by the selection of specific scales. This selection can be based on overlaps, relationships or even complementation and might also be influenced by the respective character of the scales, as they can later be used programmatically in the composition. Video examples of the application of these aspects in Christian Klinkenberg’s opera “The Glacier” are shown.


Born in Eupen (B) in 1976, Christian Klinkenberg studied composition first at the jazz section of the “Koninklijk Conservatorium Brussel” where he received a Master’s degree in 2006. In 2012, he obtained a Master’s degree in the classical section of the same institution. In May 2020, he obtained a PhD at the Free University of Brussels. The music of Christian Klinkenberg is characterized by the combination of contemporary composition concepts and improvisation. Alongside his work as a composer, Klinkenberg has continued actively as a pianist, bandleader and improviser with different performers and ensembles. Currently, he teaches at the Conservatoire du Nord in Luxembourg. Benno Bartsch (Jazzpodium 06/2016) about the music: “… Christian Klinkenberg uses very sophisticated concepts, but his music sounds anything but abstract or intellectualized; Klinkenberg produces a warm, soft sound that is also very easy to listen to …” www.christianklinkenberg.com

Milan Guštar: “All-interval rows in EDO systems”

With the twelve-tone technique and the serialism tone rows as permutations of all notes from chromatic scale were introduced in music. All-interval rows are a special subset of the twelve-tone rows and each all-interval row contains not only all twelve distinct pitch-classes but also all eleven distinct intervals between successive tones.In the microtonal music the octave can be divided into other number of equal steps than 12 and the idea of tone rows can be applied in these systems as well.

Milan Guštar is an organologist, composer, computer programmer, and designer of electronic, electroacoustic, multimedia, and interactive systems. He deals with interdisciplinary research on the border of science, technology and art, especially mathematical principles in music, theory of tone systems, electronics, computer science, applied mathematics, modeling and simulation.

Daniel Costello, horn

Costello’s concert carries the title “Acoustic Set”. “One of my motivations to present a solo program is the challenge to explore and expand the timbral and expressive range of the horn. As such, it is a rejection of electronics and visuals. The pieces feature many of the half-valve techniques I helped research with Zinc & Copper, as well as Persian scales, quarter-tones, natural harmonics (especially the 7th, 11th, 13th and many more), and vocalizing and playing concurrently. The physics of the instrument are sometimes overcome to produce tones between the natural partials, which expands the pallette of colour.”

Daniel Costello, a native New Yorker, was a freelance horn player in the US and Canada before he came to Europe. His principal teachers were John Zirbel, David Jolley and Malte Burba. Costello was appointed principal horn of La Camerata, a chamber orchestra in Athens, Greece in 1997 and later became principal horn of the Schönebeck Chamber Orchestra in Germany. In 2001, Daniel Costello was appointed associate principal horn of the Anhaltische Philharmonie Dessau, Germany, a position he still holds.

In new music circles, Costello has collaborated with Zinc & Copper, where he helped research microtonal and half-valve techniques. He has also performed all over Europe as a long-time member of Ostravska Banda. He has appeared with KNM Berlin, the elole piano trio (Dresden) and as a soloist at Jazz am Wendelstein, with the LeipJAZZig Orchester, the Leipzig Bach Orchester, the Anhaltische Philharmonie, and the Radar Ensemble. Recent appearances include the premiere of PRASQUAL’s double concerto MASHRABIYYA with the Polish National Radio Orchestra (NOSPR), Richard Ayers’ NONconcerto No. 36 with Ostravska Banda and performances of the Ligeti horn trio in New York, Ostrava, Ghent, Dessau, Lübeck and Dresden. Costello has recently translated Malte Burba and Paul Hübner’s book on experimental brass technique into English for Breitkopf & Härtel, and has lectured in extended horn techniques at the Hochschule für Musik “Hans Eisler” in Berlin and at the Ostrava Days Institute.

Erik Drescher, glissando-flute

Erik DRESCHER (b. 1972) is a freelance flutist, performer and curator for contemporary
music based in Berlin. In addition to a very active international career as a solo performer, he has performed in many ensembles for contemporary music.
The instrument played by Drescher is a glissando flute, a normal C-flute with a variable-length headjoint replacing the standard mouthpiece. Besides the possibility of producing non-step or stepless glissandi on one
fingering, you get an enormous number of new techniques. You can increase the possibilities of any given extended technique and also produce microtonal steps. The glissando flute opens up a wonderful new non-step world, a continuum of pitches.
Drescher has premiered an enormous number of new pieces, the majority of which were also commissioned by him and dedicated to him. He has been working with composers like Peter Ablinger, Maryanne Amacher, Alberto Bernal, Antoine Beuger, Annesley Black, J.-P. Caron, Axel Dörner, Sabine Ercklentz, Julio Estrada, Dror Feiler, Friedrich Goldmann, Hauke Harder, Andrew Harlan, Hanna Hartman, Michael Hirsch, Adriana Hölszky, Nicolaus A.

Dr. Margarethe Maierhofer-Lischka: “One Ear for The Past, One Ear for The Present: Aesthetics of Microtonal Composition in The Oeuvre of Klaus Lang“

Performance of Klaus Lang: die drei Spiegel der schönen Karin for double bass.
Presentation: One Ear for The Past, One Ear for The Present: Aesthetics of Microtonal Composition in The Oeuvre of Klaus Lang.
Klaus Lang, one of the most prolific contemporary Austrian composers, has become known for his specific musical language, creating works that often remain at the limit of the audible, exploring a space of softness and stillness playing with threshholds of perceptions. The composer often refers to the aesthetics of John Cage, while also affirming roots in historical music composition practices from middle-age to early Baroque music. While Lang is stressing the importance of mathematical structures, microtonal scales and temperaments for his composing process, the sounding result seems to counteract his structured approach, thus leading to the question of how structures and their performative experience play together: In which ways does Lang use microtonality to (mis)lead our attention, play games with our ears, bodies and minds to create new performative experiences?
My study presents a focused insight into Lang´s practice of composing with microtonality, connecting analytical and aesthetical reflections to present a multi-faceted view on his music. I combine an analytical viewpoint on the historical elements of microtonal composing, such as the use of scales, temperaments and enharmonic theories, with a contemporary perspective on the aesthetics of microtonality informed by the so-called „perceptual turn“ from Cultural Studies, by which the shaping and reflection on the aesthetics of perception became an important field of discussion in contemporary music and art research. Referring to Michel de Certau’s concept of an „Art of Doing“ (L’art de Faire), Lang´s practice is described as an „Art of the Undocumentable“ that is rooted in historical music thinking while moving forward into the present and future. Tricking our „rational listening“ and pushing us into immersive states of perception, Lang’s practice draw on bodily experiences, while at the same time integrating conceptual historic references to music, art and architecture. I will demostrate my theses by examples taken from several of his pieces, showing how Lang is layering (possible) meanings that unfold in sensual experience like light in a prism, using the space of performance as a threshhold to connect the past, present and future.

Public press release
March 14, 2020
Dear audience and participants of MicroFest Prague 2020,
we are sad to announce the decision that the planned events of MicroFest Prague for April 2020 have to be cancelled according to the travel and health regulations recently set by the Czech government. The regulations also affect cultural and educational events. Due the worldwide COVID-19 outbreak, however negligible in and around Prague at the moment, this week a state emergency was announced. This closes all borders to all non-Czech citizens and will last at least 30 days into the middle of April. The timing leading to the festival would be too close to reliably tell whether the border will further stay closed to the majority of our participants and visitors who are foreign nationals. Even if the borders were reopened, organising the festival as planned would not contribute to subduing infections in such an international and touristic city as Prague.

A closure until further notice of all institutions of education was announced this Tuesday.  Our sponsor and festival venue, the Academy of Performing Arts in Prague suggested this postponing measure against further infections. With it, we aim to secure organising MicroFest Prague with as much of the original substance as possible at a later date and keep participation free. We are looking to changing the timing to when the state emergency can be reasonably expected to have been mitigated, to Autumn this year. We will soon contact the presenters and performers about their possibilities of participation at those dates.

We once again apologise the situation that has emerged.

Stay healthy and best wishes from Prague,
Iva Oplištilová and J-T Vesikkala Wittmacher

MicroFest Prague 2020


What We Do

The Czech Institute for Microtonal Music is a freely formed group for people with an interest in composed, theorized, and performed music with microintervals. The Institute is led by two Prague–based experts working in microtonal music and music theory, Iva Oplištilová and J-T Vesikkala Wittmacher. The Institute exists to promote microtonal performed and composed music and research in Prague, Czechia and nearby regions as a whole, to organize scientific and international easy-access conferences, workshops, presentations, competitions and concerts, and to enrich the worldwide dialogue and flow of information on the microtonal field. Connections are maintained with multiple individuals, groups, societies and festivals, among which are EUROMicroFest, Finnish Microtonal Society, and American Festival of Microtonal Music.

From Thursday April 23rd to Saturday 25th, 2020, the Institute organizes the first edition of a festival in a format similar to the international MicroFest (running since the 1980’s), with the local title Institut mikrointervalové hudby 2020, or with the international subtitle MicroFest Prague 2020. The performing and academic festival includes eleven presentations by internationally acclaimed speakers and two concerts focusing on microtonal music, one of them for ensemble and one a recital of soloists on microtonal instruments. Moreover, three shorter concert sets titled “Open stage” will present microtonal music in a Friday evening setting.
