Vocal Spectrum is a barbershop quartet from St. Charles, Missouri. In 2004, Vocal Spectrum won the Barbershop Harmony Society's International Collegiate Quartet Contest, and on July 8, 2006, they became International Champions, winning the society's International Quartet Contest. A distinctive factor of the quartet is tenor Tim Waurick's ability to sustain notes for upwards of 30 seconds, and the tenor's and lead's incredibly high note range, featured in many of the group's recordings and live shows.
Vocal Spectrum began singing together in September 2003. Each member has graduated from Lindenwood University in St. Charles. Each member is also a member of Ambassadors of Harmony, the International Chorus Champion of 2004, 2009, 2012, and 2016. As of the 2006 International Quartet Contest, Vocal Spectrum is the only quartet in history to capture three of the then-four (now five) possible BHS gold medals (Collegiate Quartet, Quartet, Chorus [as members of the Ambassadors of Harmony]).
The only championship that remains for Vocal Spectrum to win is the Barbershop Harmony Society's Senior quartet contest for which they will not become eligible for at least three decades (no member of a competing Senior Quartet can be younger than 55 years old, and the aggregate age of the quartet must equal or exceed 240 years [average age 60 or greater]).
