The Neuroscience of Improvisation – Details, episodes & analysis

In this program, we compare dreaming and improvisation focusing on creative synergies, experiential similarities, and the underlying neurophysiology. These states of mind are mutually illuminating. That is, learning about one provides insights into the other. A key insight here is that we can deepen our understanding of improvisation by exploring other states of mind that have overlapping experiential qualities or brain states. In his book Dreams of Awakening, Charlie Morley writes that “…there are many different ways to tell the difference between [different states of experience], but the easiest way to get to grips with these differences is to spend as much time as we can in these states.” I propose that this is the case for improvisation, as well. By paying more attention to our dreaming experiences, we may deepen our knowledge of the experience of improvisation.

What is the experience of improvisation and what are its neurobiological correlates? One way to flesh out an answer, or at least to get the lay of the land, so to speak, is to look at how improvisation compares with other kinds of brain states and states of experience that have been explored with science, such as dreaming and psychedelics. That's what we're embarking upon here. In this video, you are going to discover that there are some quite interesting relationships between what's happening in the brain during improvisation and what happens to the brain under the influence of dreaming and classical psychedelics.

Prasant Radhakrishnan has a background in Carnatic Indian classical music and Western musical traditions, including jazz improvisation. Prasant is a protégé of the legendary Kadri Gopalnath, who revolutionized the role of the saxophone in Carnatic music. Prasant's performances traverse the realms of traditional Carnatic concert programs while also blurring boundaries with his VidyA ensemble and other collaborations, featuring instrumentation from the jazz tradition. Moreover, he embraces music as meditation, bringing forth unique philosophical perspectives through his artistry and teaching.

The interview covers the following topics:

• Prasant's experiences with Carnatic and jazz music
• His approach to improvisation across these musical traditions
• Experiences with his guru, Sri Kadri Gopalnath, and related insights
• Methods for learning to improvise
• Integrating meditation and music practice (including a demonstration!)
• Blending Indian and Western music traditions through composition and performance
• Breathing techniques for self-awareness
• Dreaming and improvisation
• Comparing the relationship between the Carnatic and jazz traditions and mind-altering substances and addiction

This episode shares overviews of seminal neuroimaging studies that provide insights into what happens in the brain during improvisation. You will learn how these findings align with what improvisers say about their experiences, including remarks from Bill Evans, Sonny Rollins, Kenny Werner, Pat Metheny, and Gary Burton. Cross-cultural perspectives are included here, as well, including reference to a traditional Japanese visual art form and traditional perspectives from West Africa.
