The Agidigbo is rectangular shaped. A traditional plucked lanellophone (local piano) played by the Yorubas in Nigeria. It is made from lightweight wooden box and wide metal blades and is used both percussively and melodically.
Its appearance is piano-like; a rope is worn round the neck of the player who then supports or braces the instrument, whose body is a rectangular wooden box, by his chest or thoracic region. The player wears a thick “ring,” usually a bottle neck, on his thumb, which he uses to tap the sides of the wooden box.
