In this music, there is a humming female voice. What is that called?
There's quite a lot of wordless female voice in the track, but I don't hear any humming.
The music doesn't really fit any genre, it's written to evoke a kind of general 'ethnic' feeling without actually copying a specific style. As is typical for this kind of background music, it tries to evoke an atmosphere without drawing attention to itself. So it's probably best described as "pseudo-ethnic film music"
