The neuroscience of jamming is a giant mind meld.
Guitarists perform a kind of mind-meld when they play together, syncing their brainwaves to the extent that they can anticipate each other’s moves. They also switch off the outside world while playing, leaving them in a tiny universe of them and their music.
A study by researchers Johanna Sänger, Viktor Müller, and Ulman Lindenberger used guitarists to investigate joint action, or “tasks that require the close alignment (coordination) of one’s own and the other’s action in real time.” Tasks like playing in a band or in a duet.
By measuring the brain activity of the players while they performed together, the studyfound that their brainwaves locked in sync. To preclude the possibility that just playing the same music would induce the same brain patterns in both players, the study used songs with two parts. Further, a leader and follower were assigned, one setting time and the other following.
