A method is provided for functionalizing nanoscale fibers including reacting a plurality of nanoscale fibers with at least one epoxide monomer to chemically bond the at least one epoxide monomer to surfaces of the nanoscale fibers to form functionalized nanoscale fibers. The chassis includes a front plate, a rear plate, a top plate, two side plates, a bottom plate and a plurality of dividing plates. An alternate embodiment provides the listener with convenient means to record a segment of the music in which heshe is interested.
