I collect Hand Drums.
My collection began with a small frame drum called Rebana Penganak I got in Kuala Lumpur, Malaysia.
Then I got
a Dholak from India,
a Full Circle ceramic Dumbek,
a Remo Djembe,
a Doira from Uzbekistan,
a Remo Frame Drum,
a set of 3 World Beat Congas,
and most recently a set of Tabla from India (which I'm still learning to play).
That's 11 drums so far... it's a start.
I find inspiration in the book When the Drummers Were Women by Layne Redmond.
