That's the sound of my brain growing new neural connections -- particularly in the prefrontal region of the frontal lobe. That's the part of my brain (yours too) where the executive brain functions take place. Functions such as planning, problem solving, active memory, verbal reasoning and multi-tasking.

I'm strengthening those functions by learning to play the djembe drum (tone, tone, slap, slap). The key here is not really the djembe. The key is the new learning.
In learning the djembe I am challenged by the hand positions and learning to build speed in my drumming. According to innovative thinking expert, Tim Hurson, those novel challenges can push my thinking outside of "elephant tethering" (think a huge pachyderm circling a stake to which it is tethered -- creating a deep rut) and into the productive thinking.
Not sure how to recognize productive thinking? Consider the last time you took on something completely new to you. Can you recall feeling uncomfortable, awkward and maybe even a bit uncertain? It is in that place of discomfort where the brain grows, and strengthens those executive functions. How cool that while I'm learning to play the drum, I also am charging my problem solving power and activating my memory muscles.
So whether your drum is the African djembe, a marching band bass drum or the backbeat snare drum . . . . take a listen for a new direction that will waken your productive thinking potential.
At some point, I expect I will "learn" the drum -- at least to a point when the soothing rhythm feels natural and calming to produce. I think that when it feels easy and natural, I'll enjoy my playing more . . . and then I'll look for new learning. For awhile now I've been thinking about learning to use the abacus to perform less simple math computations . . .
