I am looking for a bunch of verbs to denote various variations of a specific kind of singing, where the singer essentially… wails? There are no lyrics of any sort, the voice is essentially used as an instrument.
So far, I know of ‘howling’, which is close enough for emitting an ‘uuuh’ sound (like the vocal in ‘moon’). Imagine a pack of wolves howling towards the midnight moon. It might not be the best choice of verb to describe singing, but in some cases, it comes close (I can’t find an example right now, though).
How would one call something similar, but using an ‘iiih’ sound (like the vowel in ‘beep’)? To give an example, consider the female voice recurring throughout ‘The Beginning of a Journey’ and especially ‘Naia’.
Same thing, but with an ‘oooh’ sound (like the vowel in ‘whore’)? ‘Fresco Dome’ fits to some degree; if I find a better example, I’ll link to it.
I’m not looking for ‘to vocalise’ or similar verbs—I already know about them, and it’s the superclass of the kind of words that I’m looking for. I want to know whether there are other words similar to ‘to chant’ or ‘to howl’ for some specific cases of vocalising that might be useful for my purpose. If such words actually exist, that is. It might just as well be that there aren’t, and that this is the reason why I can’t find any.
