The World of Classical Music Nurtured by Radio

Memories of Osaka Radio and Classical Music

2026/08/08(sa.) 16:00 Starting

Higashi-Osaka City Cultural Creation Center Multipurpose RoomOsaka

The year 2026 marks 120 years since the birth of radio broadcasting using sound and music, and 10 years since the death of French composer Pierre Boulez. Classical music is closely related to radio broadcasting, and music developed at radio broadcasting stations. Boulez also studied composition at radio broadcasting stations. He pioneered new musical expression by incorporating the sound filtering and other techniques used in radio broadcasting into instrumental music expression.
Many classical composers came to Osaka for the 1970 Osaka Expo. There, experiments with technology were actively conducted, and Osaka became a "mecca for the development of classical music. In addition, radio in Osaka has nurtured a unique culture that has strengthened "entertainment" and "common people" characteristics. In this performance, we hope that the audience will experience the musical expression that developed at the radio broadcasting station and experience the connection between art and local culture that continues into the present day.

What is Aquesmonium?
This performance uses a performance medium called "acousmonium. The "Acousmonium" is a new musical instrument for playing electronic music that appeared in the 70's. It is a medium for enjoying a sense of presence and spatial expression of sound by installing many speakers at different positions and heights in the venue and playing the sound source, and allowing the performer to control (play) the volume and sound quality of the speakers.
The use of "AquaSmonium" creates performativity in the electronic sounds in "Dialogue of Double Shadows" and "Anthem 2," and enables the realization of ensembles with musical instruments. In the concert, the audience is invited to move freely and listen to the music in any position they like in order to enjoy the spatial expression of the sound. This is an ideal format for a wide variety of people, as there is no need for the audience to sit still and quietly listen to the music.

Dialogue and Anthem of Double Shadows 2 (Composed by Boulez)
As a conductor, as a composer, and sometimes as a politician. In the history of classical music, no composer has contributed more to the development of music than Boulez. This year marks the 10th anniversary of his death. Boulez also studied composition at a radio broadcasting station. He utilized the electronic technology used in radio broadcasting for live performances and established a technique for maintaining consistency between instrumental and electronic sounds. In "Dialogue of Double Shadows" and "Anthem 2," the sounds of clarinets and violins will come from all sides of the hall, allowing the audience to experience instrumental sounds they have never heard before. Enjoy the sounds of clarinets and violins in a way that cannot be achieved with live music alone.

Kuragariinoramki (Composed by Tomonori Okada)
With the birth of recording technology, sounds of nature and human speech can now be incorporated into musical expression. Music made in this way is called "music concrète. This genre was actively experimented with by radio broadcasters, and numerous technologies were created. This work will be the world premiere of a piece that uses compositional techniques developed at radio broadcasting stations to create the material sounds of Osaka culture.
The performance will use a new instrument called the acousmonium. Please enjoy the presence of Osaka culture enveloping the entire venue.
