the.com/conga drum

means A tall, single-headed barrel drum of Afro-Cuban origin, played with the hands and traditionally used in Cuban rumba and conga lines.

from The name comes from the conga line dance itself, which in turn traces to 'conga,' a Spanish term referring to music and dance of Central African origin among enslaved and Afro-Cuban communities in Cuba. The drum (properly called 'tumbadora' in Cuban Spanish) picked up the English name 'conga drum' because it supplied the rhythm for conga-line dancing when the craze spread to the US in the mid-20th century — so the instrument got named after the party it powered, not the other way around.
