Guitars And Brains: Neuroscience Synchronization Happens In Musical Duets

We musicians, simply call it "...in the groove..." when thinks 'click' musically!

I wonder if this accounts for the well known phenomena among A Capella vocalists of families having a smoother harmonic blend than non-family members. I have also noticed it among people who, though not biologically related, live together for long periods of time, and spend a good deal of free time together, even though the free time is not necessarily spent singing.

Interesting findings.

And Yes, it does occur in other cooperations too, when the partners perceive effortless sync. of their efforts. The rythm of the music is relentless and obvious for all, but the same is visible to all participants, and some observers in other areas.

So, yes, it appears to be one of the general organizing principles.
