Part three of Kaelin's mix series: the small vowel adjustments that turn a technically correct singer into a consistent, finished, professional-sounding one.

Once a singer is smooth through the bridges, what separates them from a professional? Consistency of tone — and in part three of his mix series, Dean Kaelin shows you how to build it. He reviews his four-step process from exercises to songs to style to presentation, then goes deep on the valve: finding the friendly vowel, the vowel behind all the other vowels, and how vowel placement shifts by style, forward for Broadway, centered for pop, back for classical. The highlight is a live EQ demonstration where he boosts lows, mids, and highs on a mixer, then reproduces exactly the same changes using nothing but mouth shape and larynx position. Three singers close the session.
