One of life’s greatest pleasures
Watching music being created live is, for me, one of life’s greatest pleasures. Maybe it is the intensity of the emotion that it generates, or the hypnotic effect that it can wield, or perhaps it just plays into the love of art being created in front of us. As an observer, it can still feel like a collaboration – the emotions of the audience and musicians colliding over and over creating a pure “in the moment” feeling that is utterly unique.
Being present at a recent performance of “The Gloaming” was one such moment. Highly regarded performers each in their own right, together this group of musicians have created a magical re-interpretation of Irish Traditional music, which has bewitched many. Listening to The Gloaming is like hearing music anew, as they create something entirely different and spellbinding each and every time.
The interaction between the two fiddle players always brings to mind a conversation of the best kind – deep in thought, leaning in towards the other, attentive listening, and space to speak and be heard. A kind of musical empathy, if you will. To watch these musicians make music live is exhilarating. To borrow the words of Seamus Heaney, like all great art it can
“Catch the heart off guard and blow it open.”
All that Jazz
But of course, the genre best known for its “in the moment” creation would probably be Jazz, bringing the music of John Coltrane, Myles Davis and Thelonious Monk to mind. The extraordinary Jazz pianist Keith Jarrett is famous for improvising entire concerts on the spot, to the delirium of his fans. But improvising is not just a solo experience; it can be a collaborative process too. Just listen to the live recording of Ella Fitzgerald and Duke Ellington singing “It don’t mean a thing”, an exuberant version which has Fitzgerald scatting (vocal improvising) for four bars of song with the saxophone player scatting back, complementing her phrase with his own interpretation. Back and forth they go for an entire chorus culminating in a frenzied climax to the delight of the audience. It is impossible to listen to and not to smile
Can we visualize creativity?
What’s happening inside the brains of a Fitzgerald, Davis, or Coltrane when they create this music? Scientists have long been fascinated by the question of creativity and what it involves, and with the advent of fMRI (functional Magnetic Resonance Imaging) scanners, we have been given a glimpse of the brain in action. While we may not be able to see creativity, we can observe the brain when the creative process is in action – a sort of proxy perhaps?
Dr Charles Limb and colleagues, at Johns Hopkins University, has been at the forefront of researching creativity through music. As an accomplished jazz composer and musician himself, Limb felt that observing the brains of Jazz musicians while improvising (inside the fMRI scanner), could give us some answers about the creative process.
In an engaging TED talk, Limb describes how they looked at the brains of expert jazz musicians when they played memorised musical tasks and when they were improvising.
On a specially devised un-magnetised piano keyboard, an expert jazz musician played a pre-learned scale up and down, an original piece which they had memorised, an improvised scale and finally they ‘traded fours’, with another jazz musician, outside the scanner.
Trading fours is a well-known back and forth improvisational exchange where a pair of musicians alternates four bars apiece, feeding off each other – you don’t know what’s coming musically, but you need to react instantaneously – and so it goes, back and forth, between musicians.
The results showed strikingly similar patterns of brain activity when improvising the scales and trading fours. The part of the Frontal lobe known as the Medial Prefrontal Cortex (MPFC) was active while the Lateral Prefrontal Cortex (LPFC) was deactivated. This is interesting because the active MPFC is involved in self-expression while the deactivated LPFC is involved in self-monitoring and self-observation. Limb and colleagues described it thus….
“The brain deactivates the area involved in self-censoring, while cranking up the region linked with self-expression.
Effectively, the musician shuts down their inhibitions and lets their inner voice shine through”
It appears that one area turns on and another turns off to allow you to take risks musically, and be willing to make mistakes without fear of self-judgment.
A kind of conversation
Additional studies on jazz improvisation have suggested that the areas of the brain associated with speech and language are active during improvising music – but in quite different ways. The parts of the brain associated with interpreting the structure of language and phrases (syntactic regions) is robustly active, but the part which processes the meaning of language (the semantic regions) is quiet.
“I figured we would have the involvement of language areas during spontaneous musical conversation, but I did not really anticipate the semantic area would be deactivated the way it was.”
“Syntax has more to do with grammar and the structure of language — basically the rules of language,” Limb explained. “Semantics has more to do with the meaning of words. So, if music has semantics, it’s not processed in the way that is traditionally used for language.”
Lost in the music
Watching performers such as The Gloaming weave their musical spells the idea of being ‘lost in the music’ easily comes to mind. But as they close their eyes and seemingly enter a trance state, they are not just waiting their turn – further research from Limb and colleagues suggest that musicians enter states of creative, heightened awareness with all of their senses acutely tuned to the flow of music and allowing them to follow and respond
“even though a performing musician may lose track of her actions, she is at the same time in a heightened state of awareness—tasting, smelling, feeling the air around her.”
In a lovely illustration of the brain’s wondrous abilities, the same brain patterns that are present during deep REM sleep and dreaming can be seen when improvising, leading the researchers to suggest that the musicians may in fact be in a kind of waking dream.
Are we not all improvising?
While the lure of a “waking dream”, induced by reaching the heights of musical mastery, may seem out of reach for most of us, creative improvisation may not be the exclusive domain of jazz musicians, rappers or slam poets. Are we not all improvising in a way, in our movement and our speech, in our telling a story, arguing a point or when we are engaged fully in a conversation?
Maybe our ability to improvise is a key part of the back-and-forth nature of our interactions with each other? In using our creative and improvisational skills when we interact with the patients, in trying to make sense of new information?
Perhaps it really is a kind of verbal trading fours! Too far? Perhaps, but maybe not.
