These Drums are very low pitched and are tuned to the pitch of the human heart beat. They offer a versatile and big sound at a price that anyone can afford. Untreated cow skin heads with rum barrel oak shells and a one year warranty on the wood make these bombas a drum that every player will enjoy for years to come.
