The bardic tradition required a performance where the poet/singer needed to engage an audience with both a performer's and various poetic personae. As a performer, the bard was in a similar position to a poet today at a reading of his or her work. In addition, the poem (traditionally an epic) required the representation of a large number of "speakers", or characters in the poem, each possessing a distinct voice. The bard's challenge was to be fully present, engaging the audience in their world, while manifesting the world of the poem in the imagination. How did the bard hold the audience.
This is an issue we will return to. For now, spend some time immersing yourself in epic material. Spend some time reading and speaking (applying Packard's approach) epic poetry. Two good places to begin are Homer's Iliad and the Old English epic, Beowulf.
Suggested translations for Homer include those by: Robert Fagles, Richmond Lattimore, and Stanley Lombardo. Suggested translation for Beowulf is by Seamus Heaney.
Also, become familiar with the work of performers such as Benjamin Bagby who currently present epic in performance in a way close to the spirit of the original.
