Riggs started singing when he was about 7 years old, and joined the Washington National Cathedral Boys' Choir as a 9-year-old.[8] Riggs has been a vocal coach since 1949, when he was serving in the Navy as a gunner.[9][10] He "received his music education from Peabody Conservatory of Music and Manhattan School of Music", and also received a B.A. in drama from Johns Hopkins University.[11] After receiving the Distinguished Alumnus Award from the Peabody Conservatory, Riggs gave a masterclass which Richard Cassilly attended, and afterwards asked Riggs to help him with his voice.[12] Riggs studied voice with teachers including American baritone John Charles Thomas and Italian tenor Tito Schipa,[11] and in New York City with Keith Davis who was at the time teaching the majority of singers on Broadway.
Riggs conducts workshops and masterclasses around the world, as well as teaches private lessons together with his wife, recording- and performing artist as well as voice teacher Margareta Svensson Riggs.[13][14]
Riggs created SLS that blended singers’ head voice and chest voice while applying SLS (speech level singing) techniques that benefited Michael Jackson, Prince, Stevie Wonder, Madonna, Barbra Streisand, and numerous others. In 1995 SLS's CEO, Dave Stroud, developed a teaching platform, which was implemented in 2000, requiring all of SLS's vocal teachers to undergo lessons and testing from one or more of seven SLS master classes and would be tested and approved if they were to be associated with Seth Riggs.[15][16][17]
Riggs is married to singer Margareta Svensson,[18] The two met when Svensson came to Seth Riggs for singing lessons in 1995. In 2008, they became a couple, and four years later, in 2012, they married and their daughter Samantha was born.[19][20][21]
