e-scale

Updated: May 25, 2025

I tried her voice with the E-scale before using the laryngeal mirror, and to my utter surprise found the medium G sharp missing, while all the rest of her scale was perfect even to the G sharp above. This experiment was tried repeatedly with the vowels a, e, i, o, and u, and with consonants prefixed, but invariably with the same result.
