The udu is a traditional clay percussion instrument from the Igbo people of Nigeria, where its name means vessel or pot. Made from fired clay with a side hole, it has been played for generations in ceremonies and folk music before finding a wider audience through world music recordings and sample libraries. As short audio clips and sample packs spread online, the distinctive watery bass hit became easy to drop into edits, beats and sound design, and it remains popular for adding an organic, handcrafted texture that synthetic drums rarely match.
