André Leroi Gourhan differentiated between two main percussion techniques, i.e. the perpendicular percussion by pestle and mortar (which corresponds to the ‘crushed’), and the oblique percussion by grinding stones (which corresponds to the ‘ground’).

Since antiquity, technical innovation and large scale production have led to the design of mills. In many traditional civilizations, the rhythmic crushing or grinding was reflected by songs imitating the noise of these labours or helping to maintain a certain cadence (software Realplayer required).
