Performance   Education   Research   Transformation

ISIM promotes performance, education, and research in improvised music, illuminating the transformative impact of improvisatory creativity in education and society at large.

Melding diverse cultures, ethnicities, disciplines, and ideas that shape our lives, today’s musical world is increasingly characterized by creative expressions that transcend typical style and genre categories.

Improvisation is a core aspect of this global and transdisciplinary confluence.

ISIM brings together improvising artists, pedagogues, scholars and social visionaries to explore and develop this core facet of human creativity in the 21st -century.

In the performance realm, ISIM works to provide space for diverse kinds of improvisatory collaborations by convening improvisers from around the world.

ISIM’s educational commitment lies in developing pedagogical models that foster both genre-specific and stylistically open improvisatory skills, creating collaborative learning environments that transcend conventional student-teacher roles.

ISIM promotes research into the wide-ranging creative, theoretical, cognitive, cultural, spiritual and aesthetic dimensions of improvised music.

ISIM is also deeply committed to the transformative dimensions of improvisatory creativity and its wide-ranging ramifications for society at large. In the consciousness/spirituality realm, for example, a long legacy of improvisers have engaged in meditation practices and viewed their art as a vehicle for connection to the sacred. The African American roots of much improvised music, particularly when situated in broader educational and societal contexts, invite engagement with issues of social justice, race and gender.

There is great potential within many improvised music-making practices to cultivate deep connections between people and their environments, transcending ideological divides. We believe that this potential has ramifications for ecological sustainability and global peace.


Founder's Message

Ed Sarath, ISIM Founder and President

Why ISIM? Do we really need another organization, another email list, another newsletter, another conference to attend? The more I think about these questions, the more I return to the core idea of the organization, and why ISIM is not only needed, but has the capacity to be truly unique among music organizations.

We have entered an extraordinarily exciting time in the history of music, when musicians have access to an unprecedented expanse of influences and creative strategies. While improvisation in one form or another is increasingly central to this global synthesis, a significant gap looms between the improvisation-based aesthetic paradigm that guides musical practice, and the aesthetic awareness that prevails in the music industry, academic musical world, and society at large.

In both the commercial and academic sectors, music that does not readily fall into existing compartments tends to be marginalized. In musical study and research, long oriented toward interpretive performance and analysis of composed music, the notion of music that is spontaneously created and performed challenges conventional assumptions about musical structure and worth. As a result, improvisation is relegated to the fringes of both research and curricular programs. Even after decades of appeals for reform, the majority of music majors still graduate with little or often no experience with improvisation. And in jazz education, while improvisation is well-covered, it is confined to a relatively narrow stylistic expanse in light of the richness of the jazz tradition and the overall musical world. (ISIM strongly advocates both style-based and trans-stylistic forms of improvisation.)

We are compelled to address these problems not just because they may affect our personal work, but also because they reflect a lack of awareness of the unifying and transformational power of music and art that is undeniably important to our times. Stephen Nachmanovitch compares the peak experiences possible in improvisation to the “ecstatic states of the Sufis,” as a result of which “performers, audience, instruments, the room, the night outside, space become one being, pulsing.” In Melba Liston’s words, “everybody can feel what each other is thinking . . . You breathe together, you swell together, you just do everything together, and a different aura comes over the room.” A new aesthetic paradigm emerges that is grounded in the simultaneity of creation and performance, the merging of artists and listeners, the communion between musicians of highly disparate backgrounds, and ultimately the access to deeper dimensions of consciousness through improvisation’s spontaneous and integrative creative pathways. When Steve Lacy stated “there is a music that must be composed. There is another music that can only be improvised,” he was not dismissing composed music—the beauty and importance of which few would deny—but rather he was acknowledging the uniqueness of the improvised.

A wider embrace and understanding of improvised music may also offer insights into creativity in a variety of fields. Central to success and fulfillment in a variety of fields—from sports, to medicine, to business, to education—is the ability to engage in moment-to-moment creative activity that is highly improvisatory in nature. While ISIM’s primary thrust is, naturally, improvisation in music, the probing of extramusical ramifications can be seen as an organic extension of this process, and a cross-disciplinary approach to improvisation may even in turn illuminate improvisation in music.

ISIM brings together artists, listeners, teachers, critics, scholars, and industry leaders to celebrate the unifying power of improvisation in music and beyond. Please consider joining us in this important and exciting endeavor.



In the educational arena, ISIM promotes the creation of pedagogical materials that foster the development of improvising skills. At present there is a large volume of style-based improvising methods, particularly in jazz, and these are of great value. However, there is a great shortage of methodologies that deal with improvisation from what might be called a “trans-stylistic” vantage point, methodologies that focus on the processes of spontaneous invention and interaction as they might apply across styles. The ability to transcend stylistic boundaries is very important for today’s musicians.

ISIM will lobby for curriculum reform, and play a pro-active role in designing curricular initiatives in which improvisation is a central aspect of musical study. This is the mission of the ISIM Curriculum Project, which will explore new possibilities for a core curriculum for our times.

ISIM Conference is hosted annually beginning in 2006. The purpose of this conference is to host workshops, seminars, research presentations, and training of all kinds by experts on improvisation from all over the world.
ISIM creates Student Chapters in public and private schools. These chapters are led by a faculty advisor, serving functions including creating a local support system for improvised music, hosting local performance events and workshops, and establishing student networks world-wide.
