Psychologists argue that music is far more powerful than language. This is because, in addition to its commonality across borders of culture, race, and nationality, it also has the ability to arouse out feelings and emotions.

An increased interest in how the brain processes musical emotion can be attributed to the way in which it is described as a “language of emotion” across cultures. Be it within films, live orchestras, concerts or a simple home stereo, music can be so evocative and overwhelming that it can only be described as standing halfway between thought and phenomenon.

It also gives us a way to express our emotions in ways that language never could.

Scientists have further discovered that when attempting to express their emotions through music, the brains of musicians work in a very odd but interesting way. A brain-scanning study published in the Scientific Reports journal was carried out that examined jazz pianists as they played. The researchers found that strong emotions have the ability to alter how the brain networks responsible for creativity work.

“It seems that the link between emotion and creativity is truly fundamental, and we suspect, ultimately responsible for the perseverance of creativity throughout human history,” Dr. Charles Limb, a University of California, San Francisco, neuroscientist and one of the study’s authors, told The Huffington Post in an email. “Humans seem to need creativity in order to understand and examine the human experience, which is (in our opinion) a deeply emotional one. For these reasons, we wanted to understand how emotion modulates brain networks for creativity, during real time spontaneous creativity in expert musicians.” Via Huffington Post

Creative processes involve different networks, regions, and processes in the brain, so they cannot even be attributed to any one network. The researchers found that when musicians attempt to express their emotions during the creative process, parts of their brains involved in emotional expression are also activated.

Limb, who is also a jazz saxophonist, has previously conducted research that found that musical improvisation deactivates a key brain region involved in planning and monitoring behavior — the dorsolateral prefrontal cortex (DLPFC). This suggested that the silencing of the DLPFC may be responsible for the artist’s ability to enter a “flow state” of deep absorption and free-flowing creativity. Via Huffington Post

Building on this discovery, the researchers wanted to find out what effect emotions had on a musician’s ability to enter a flow state. Jazz pianists were asked to improvise a melody on a small keyboard as a brain-scanning machine observed their brain activity. The melodies were to express a positive emotion or a negative one.

The fMRI scans revealed that DLPFC deactivation was significantly greater when the musicians were trying to convey a positive emotion in their improvisations. When trying to express negative emotions, on the other hand, there was greater activation of the reward systems of the brain. Via Huffington Post

These findings suggested that getting into the zone was easier when a musician is creating happy music. The researchers also concluded that musicians seemingly enjoyed creating sad music, but this was different from that of creating happy music. The study revealed that the way the brain works during creativity is influenced by the emotions a person is experiencing at the time, and this applies to both positive and negative emotions.

Why Improvisation Should Be Part of Every Young Musician’s Training

creativity postMuch is often made of the Suzuki method as being a system of learning that fails to nurture creativity. I don’t know if this was part of Dr. Suzuki’s original philosophy, or if I had liberal Suzuki teachers, or just a forward-thinking mom, but I actually remember being asked to do a lot of free improvisation as a Suzuki kid. Almost on a daily basis, I’d have to pick up the violin and create something from scratch. It was as much a part of my practice routine as scales. And it actually came in handy on at least a few occasions, when I experienced a memory slip and desperately improvised my butt off until I could find my way back to something familiar.

Teen classical musicians learn how to throw out the sheet music and improvise

scprAs if being a teenager doesn’t come with enough anxiety, try deciding to pursue a career as an artist at the same time. Luckily for aspiring creatives, organizations such as the National YoungArts Foundation have been guiding high schoolers through this process since 1981.

YoungArts provides scholarships to fledgling artists of all disciplines: actors, filmmakers, painters, writers, musicians and more. They also put on regional programs — in Miami, YoungArts’s headquarters, as well as New York and Los Angeles — where winners can receive a week’s worth of coaching from professionals in their field.

Vancouver Improvised Music Meeting 2016: Improvising is exciting, especially when it works

the provinceCollaboration is the name of the game at this week’s Vancouver Improvised Music Meeting 2016.

Three evening sessions, Thursday, Friday and Saturday, will feature creative spontaneity, courtesy of some of the Lower Mainland’s leading sonic adventurers and guest trumpeter/composer Lina Allemano, of Toronto, and Seattle singer/composer/pianist Robin Holcolmb.

Presented by Barking Sphinx, previous years have boasted some dynamic and one-of-a-kind sonic dialogues of the sort that Allemano says are the love of creative players everywhere. Via The Province
