Public press release
March 14th, 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

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.

As of February, the first version of the festival programme has been published.

Our lecturers and performers include Robert Hasegawa, Klaus Lang, Marc Sabat, Margarethe Maierhofer-Lischka, Erik Drescher, Linnéa Sundfær Casserly, Daniel Costello, Ivan Boreš, Christian Klinkenberg, Juuso Kunttu, Edward Powell, Milan Guštar, Petr Pařízek, Stephen Altoft, Donald Bousted, and Schallfeld Ensemble.

Institut mikrointervalové hudby is financially supported by the Music and Dance Faculty of the Academy of Performing Arts in Prague (HAMU).


13 works were selected for the festival concerts as a result of the four Calls for Works.
