Ottava

In literature, the Ottava rima is a form of poetry consisting of eight line stanzas and the rhyme scheme ABABABCC. Originating in Italy, it is typically used for epic and narrative poetry, with famous examples including "Jerusalem Delivered" by Tasso, "Don Juan" by Byron, and "Sailing to Byzantium" by Yeats.

As a musical term, "ottava" is used to describe a direction on sheet music, that indicates the notes should be played at an octave lower or higher than written.

And as a name? It might be used as a wordy choice, however, it could also be considered a variation of the more familiar Octavia. .

Pronounced ot-AH-vuh.
