Playing djembe and dunun has taught me...
... to listen
... to have more balance between music and silence
... hear and think in a different way
... learn new skills; things I never dreamed I could do
... know that every voice is valued and valuable; that there are no "small" or unimportant parts in the ensemble (or in the people who play them)
... that dance and music are one thing; dancers move, they give their music/movement to us, and that calls forth a never-ending dialogue between those who dance and those who play the music
... to be more at peace with myself
... to be happy in the moment, to have real joy in music and in life
... that impossibilities are possible - what I could not hear, I now can play, or will be able to play.
... that music and dance can create community; not competition, but a desire to call forth the best in others and in myself
... that watching others grow (in music and in dance) is a beautiful thing, and that perhaps I was/am able to help them in that growth, to encourage them to come forward and just be
... that patience and humility are vital.
... that I'm not alone
I'd say that's a pretty good start, no?
