I need help. Details below.

It concerns Starlight Sorrow's unfinished second cheeapter.

In one part, Zel speaks to Zillie in a dream. I'm trying to think of a single word description of a zebra's voice that isn't "Africanesque" or anything like that. (e.g. A word that would describe Fluttershy's voice is sweet, a word that would describe Rarity's voice in certain times is melodramatic. I'm looking for a word that would describe Zecora's {and thus Zel's} voice.)
