Is there an answer for this question i am trying to figure this out rn. if you can thanks:)
I believe the correct answer is: a. Control of Phonation.
"Raspberries" are examples of sounds made in the control
of phonation stage of child’s language development. The control of phonation
stage (from 1 to 4 months old) is when the lips and tongue become more
coordinated with phonation, and child begins to say consonant-like sounds,
although these are not yet fully formed.
It’s only changing the arpeggios! which would mean the answer is a! at least i think. i should know since it’s my 3rd year in advanced band and second in jazz hahaha
The Cult of the Virgin is the answer I'm pretty sure
