The author develops his previous hypothesis of a skin-self, showing the importance of the auditory environment in the earliest development of the Self. He presents the case of a patient in whom certain Ego functions had been inhibited by the abruptness in the intonation of his mother's voice. Using semiophony as an illustration, he draws a parallel with the fact that a harmonious musical bath assists the reeducation of children suffering from language problems. He enumerates those defects in the sound mirror provided by the mother, which are pathogenic in relation to the child's narcissistic integrity: dissonance, abruptness and impersonality.
