The tabla is a membranophone percussion instrument (similar to bongos), which is often used in Hindustani classical music. It is used in Indian folk music and is a part of Hindustani music art. The instrument consists of a pair of hand drums of contrasting sizes and timbres. It appears similar to their Afro-Cuban/Latin-American drum-based relatives bongos. However playing Tabla is very different to these. It is a mathematically calculated process. The right hand drum is called a tabla and the left hand drum is called a dagga or baya.
