This can be integral with the comb (the diatonic harmonicas, the Hohner Chrometta), part of the cover (as in Hohner's CX-12), or may be a separate unit entirely, secured by screws, which is typical of chromatics. In many harmonicas, the mouthpiece is purely an ergonomic aid designed to make playing more comfortable. The tabla is a popular Indian percussion instrument (of the membranophone family), similar to bongos, used in Hindustani classical music and in popular and devotional music of the Indian subcontinent.
