Speech Level Singing (SLS) is a world-famous vocal methodology built on a simple premise: singing should feel as natural, comfortable, and effortless as speaking. Developed by legendary vocal coach Seth Riggs, SLS focuses on stripping away the strain, muscle tension, and forcing that often happen when people try to sing. It was popularized by some of the most celebrated voices in music history, including Michael Jackson, Stevie Wonder, Barbra Streisand, and Ray Charles.
SLS is a highly versatile technique geared for singers of all skill levels and musical genres.
Unlike classical training, SLS is tailored for commercial contemporary music (CCM) like pop, R&B, rock, country, and musical theater. Singers who need to protect their vocal health during rigorous touring schedules rely on SLS to maintain stamina and avoid vocal fatigue. It is highly accessible for people who have never had private voice lessons because it utilizes the natural speaking voice they already use every day.
