Comment: This lessons shows the importance of making the head voice dominant, especially in the upper passaggio and how different vowels have different register balances.
Quote: The essential factor in singing is lyricism, and it is the so-called "head" register which infuses the voice with its lyrical properties. Thus, to drop out this mechanism and CHANGE to the "chest" register only serves to destroy the properties of lyricism which should be present even when the action of the "chest" register is dominant. In a correctly functioning registration the upper of the two registers never ceases to be an active participant, and vice versa. The concept of the register function as "changing" from one to the other is invalid. A correct technique always finds its expression in a DUAL registration in which the ratio and proportion of tension shared between them are ADDED and SUBTRACTED. (The Free Voice)
