From a construction point of view, the bouzouki can have differences not only in the number of strings but also in other features, e.g. neck length, width, height, depth of the bowl or main body, the width of the staves (the wooden gores or slices of the bowl) etc. These differences are determined by the manufacturer, who in his experience and according to the sound that the instrument should make, modifies his functional elements to achieve a more piercing, deeper or heavier sound.
