The "haftarah" is read with cantillation according to a unique melody (not with the same cantillation melody as the Torah). The tradition to read "Nevi'im" with its own special melody is attested to in late medieval sources, both Ashkenazic and Sephardic. A medieval Sephardic source notes that the melody for the "haftarot" is a slight variation of the tune used for reading the books of Nevi'im in general (presumably for study purposes), and Jews of Iraqi origin to this day preserve separate "Neviim" and "Haftarah" melodies.
