Coreen Sheehan knows how to sing. It’s how she’s toured all over the world fronting powerhouse rock ‘n’ roll bands and why Sheehan’s been employed by Grammy winners and helped countless singers prepare to compete in both U.S. and international versions of shows like NBC’s The Voice and American Idol.

In fact, the vocal technique curricula she developed is used by the Musician’s Institute Hollywood, in music schools across Japan like the Osaka School of Music and the Fukuoka School of Music, in the Taipei School of Music in Taiwan, and why Sheen has two instructional books with Hal Leonard Publications.

“That is a footprint of my work,” Sheehan told me on the most recent episode of the Load Out Music Podcast. “And because I’m so meticulous in making sure that a vocalist is absolutely prepared…mentally and physically.”

Sheehan has worked with a who’s who vocalists while receiving honors like the Vocal Instructor of the Year Award in 2008 and Curricular Appreciation Award 2014 from Musician’s Institute Hollywood. She was also nominated for the Grammy’s Music Educator Award in both 2013 and 2014, and recognized by the Recording Academy and Grammy Foundation for her excellence.

“Some of the artists are out touring 18 months of the year and they just can’t have a bad day,” she said adamantly. “I don’t care if you’re signed or not. I’ll only work with musicians, vocalists that are really serious about wanting to upgrade their voice…because that’s what you have to do. To be a professional you have to be consistent.”
