Transmission is a communicative process requiring a binary: one individual or group who actively transmits information in some form to another individual or group. Each of these is a defined role in the folklore process. The tradition-bearer is the individual who actively passes along the knowledge of an artifact; this can be either a mother singing a lullaby to her baby, or an Irish dance troupe performing at a local festival. They are named individuals, usually well known in the community as knowledgeable in their traditional lore. They are not the anonymous "folk", the nameless mass without of history or individuality.
