What drums are traditionally used in Samba?
Samba band
Snare drums
A samba band normally consists of  Tamborims
, Snare drums (Caixa),  Agogo bells, surdos,  
Ganzás / Chocalho (shakers), Cuíca, Timbal, Pandeiro, and the Repinique  (often played by the leader for calls)  whistles (at the beginning to give the samba a beat). The Apito is often used by the leader to signal breaks and calls.  
Other instruments have been added in many samba bands such as frigideira, 4 stringed guitars, 7 stringed guitars, trombones and Singers.
A small set of samba drums in the UK costs around £300. More expensive sets come with more drums enabling more players to join; a convenience due to how many would usually take place in the orchestra.
