Singing Refinement

“Sheila Dugan has trained dozens of singers who have performed at THE MUNY through the years. Children, teens, adults … all ages of her students have been represented on THE MUNY stage, as well as Broadway stages and stages around the country. Good training shows!”

Denny Reagan, President and CEO St. Louis Municipal Opera (THE MUNY)


“Everything Sheila Dugan has taught me has been immediately applicable to everything I sing…and it’s really cool! Everyone who hears me notices the difference!”

These technologies are designed to build muscles in specific ways for the singer’s specialized performance area. The exercises also build breath and breath management skills, flexibility, range, endurance and accuracy of intonation.

The second portion of the lesson is devoted to building functional and artistic control over assigned repertoire or repertoire brought in for performance refinement. Assigned repertoire is given first as an exercise to challenge skills that need improvement. Once this is accomplished, the repertoire is polished as an artistic challenge.

By doing this, you build a portfolio of repertoire that is appropriate for you, your interests, and your age. You will develop a portfolio of songs that show off your voice and artistic skills.

Additionally, I LOVE to teach adult students who are coming back to improve or advance their current techniques. These students still want to perform, or are currently performing as soloists or choristers in classical, musical theater, or contemporary venues. It is exciting to help singers shed years of bad habits from poor training or made-up survival technologies.

It was with great pleasure that I provided the Fine Linen Theatre Organization of Rolla, Missouri (, a vocal workshop on November 2 and 3, 2018, at the First Baptist Church of Rolla. I have been working with some of the most wonderful talent from Rolla and the surrounding area for the last several years. The workshop dealt with basic vocal technologies: breathing, breath management, placement and artistry. More than forty brave souls joined together for what was a very fun, and very intensive learning experience! I had the room full of singers sounding like a mature professional, theatrical choir by the end of the first night, and there are forty-plus people who would agree! I had so much fun! This was the first time I remembered to have someone photograph an event so I could share an example of this service I offer with you.

“Fine Linen Theatre was thrilled to host Vocal Coach Sheila Dugan for a Vocal Workshop and Masterclass in November, 2018.  It was incredible the amount of information, practice, and improvement that Ms. Dugan was able to include in the short two-day workshop.  Students were exceptionally impressed and excited about the experience and we’ve seen long lasting and significant improvement in multiple areas of vocal proficiency. 

The material was relevant to our Musical Theatre program and in a multi-faceted teaching style, Ms. Dugan was able to correct many bad habits, misconceptions, and ignorance.  She quickly gave the students the understanding of concepts of anatomy, physics and art to apply to their music.  Particularly impressive was the skill and speed with which Ms. Dugan was able, during the Masterclass session, identify and correct each student’s particular weaknesses and needs.  Not only was this very beneficial for the individual, but the other students were able to see demonstrated and reinforced the lessons and skills previously explained. “
