On a larger structural level, there are semi-independent musical units or blocks, which, when placed within a compás and assembled, create a piece. These components include rasgueos (here I refer to the structural unit, which is comprised of the technique mentioned above), falsetas, llamadas (Eng. call), cierres and remates.
Where it comes from
From Andalusian Spanish rasgueo, regional form of rasgueado, from the verb rasguear (“strum”). Attested in English from the 20th century (see quotations below).
