The reco reco has experienced a comeback in the past few years since the Samba schools rediscovered the 'dirty', penetrating sound of this unique instrument. The player rhythmically strikes the metalic springs with a metal stick and produces various tones by muffling the springs down with either the thumb or some tape. The reco reco functions in an ensemble like a caixa, you'll see it often in Pagodes where it creates the base for all other instruments. Try also using it as an effect instrument!
