This kind of piece is really a theme and variations. Another common type of piece is the Prelude and Fugue, two movements. The first is free-form, often melodic like a short sonata, or constructed of chords; the second is made like a round, like Row, Row, Row Your Boat except WAY more complicated.
Borne [borne] as a boys' name has its root in Middle English, and Borne means stream. Borne is an alternate form of Bourne (Middle English): place name.
Old English past tense bÃ¦r became Middle English bare; alternative bore began to appear c.1400, but bare remained the literary form till after 1600. Past participle distinction of borne for carried and born for given birth is from late 18c. To bear (something) in mind is from 1530s.
