(Does the same infant or young child cry or scream all the time, & on successive occasions, in about the same pitch of voice?)
(Do different infants or young children cry at about the same pitch of voice?—)
(The same questions about laughter.)—
(When young children are impatient & call louder & louder for anything, does the pitch change?)
(If the pitch changes during crying or laughter, or impatience or crossness, I shd be very glad of any remarks on the nature of the change.)— (Is the pitch higher in crying or screaming than in laughing?)2
