The correct answer is: By hitting the surface


    The above musical instrument can be made to make sound by hitting its surface.
    • The sound of musical instruments can be produced by various means.
    • For example, the piano by hitting the keys, and the guitar by plucking its wire.
    • The sound in a tabla or drum can be produced by hitting its surface.
    • When the leather surface thumped or a membrane stretched, wither by fingers or palm.
    • The waves thus created travel in two dimensions and produces sound.
