THE Real Transformations from Singers & Teachers

Real stories from singers and teachers who elevated their vocal mastery.

My voice never gets tired anymore! My confidence soars!

I started learning performance mode and the Commands when I was in 8th grade. Before that, I was the most defensive teenager you would have ever met.

I had zero confidence in myself and took everything so personally.

After learning about Performance Mode, I gained so much more confidence and had more of an open mind than just making the assumption that I was always right.

The person I am today is what the younger me wished could be back then. That ‘me’ would be thinking “if only I had that confidence in my singing and my day-to-day life.

My voice can do almost anything I want it to do! The Commands gave me a variety of abilities to sing in different styles of my choice. When I have an acting role, the Commands serve to keep my voice from fatigue as well.

Chrissellene transformed my voice!!!

I’m a seasoned professional singer and voice teacher. Before I studied with Chrissellene, I had “blown my voice out” to the point where I’d lost most of my upper register, couldn’t sing for even a few minutes long without vocal fatigue, and I would even cough while trying to sing.

I tried everything I knew in my training to correct the issues and nothing was working. I even quit singing for several years. It was so sad.

Thanks to Performance mode, Instead of just reacting emotionally I can stop myself and think about why I’m reacting and choose to do something different that’s focused on finding a solution to the problem rather than being defensive. Thank you Performance mode!

Real stories from actors & comedians who elevated their vocal mastery.

Performance Mode & the Commands are game changers for any performer!!!

The Vocal Commands should be followed like Commandments. The Commands allow you to be as versatile as you could ever dream to be, and yet they can also provide help to specific problems, when need be.

My passion lies in classical drama, and so, I thought the Commands wouldn’t help me. I thought they only applied to singing. I was wrong. The Commands can help anyone with any type of performing – or even with speaking.

Read More

What Chrissellene taught me is that it doesn’t matter if you are singing or speaking, the Commands allow you to protect your voice and use it to its fullest capabilities.

As wonderful as the Commands are, Performance Mode is that much better. It allows you to strip away all the unnecessary emotional reactions that many performers deal with on a day to day.

For me, Performance Mode has pushed me ahead in my theater work. With Performance Mode, I can focus on the performance and on my abilities.

Susannah Eig-Gonzalez

Actor

I stopped taking EVERYTHING personally and found my confidence!

I’ve been studying with Chrissellene for over seven years now. I have a Bachelor’s in Music in vocal performance, which is to say I sang opera for a while. But even after that, I still didn’t know how to really control my voice, and I had a wobble.

Every time I didn’t get a role it was because I wasn’t good enough, any time anyone said anything at all, I would go on the defensive. She helped me find the confidence to audition for graduate school in acting, and now I’m a New York-based actor, no longer afraid of putting myself out there because of what others might think.

I’d probably still be a 36-year-old loser, with the emotional strength of a toddler and no confidence to get out there and really push myself.

At best, she may be a genius in her field that has discovered truly valuable information!!!

Her name is Chrissellene Petropoulos and she is for real. I say this because to actually meet her is to encounter such exuberance, optimism, and vitality that one’s first reaction justifiably is, “Hey, no one could be this upbeat and be for real.”
Chrissellene is, at least for the past 25 years I have known her. And she’s real-world smart.

I met her at Strathmore Arts Center a quarter of a century ago when she offered to help us get started in Montgomery County. A world-experienced singer and vocal coach, she puts her whole heart into whatever (and whoever) she is teaching.

Over the years since then, I have watched her add wisdom to her incredible knowledge base, creating value far beyond most of her contemporaries, especially in the development of the voice.

Recently, she came to my office and briefed me on her project of the last 12 years, The Technical Commands to Vocal Mastery. I was struck by the science behind the technique and the subsequent methods she developed to take the mystery out of vocal training. It may not endear her to some voice teachers who depend primarily on visualization techniques because her methods debunk many of the classic vocal coaching techniques by using real-time MRI images of proper throat posturing and control.

I believe she and her colleagues have finally done the hard work of scientific research made possible by the invention of new, innovative, and non-intrusive medical diagnostic technology. Good for her.

I commend her to you. All I ask is that you give her an audience, if she requests one. It will not be a waste of your time or attention, even if your missions don’t eventually align. At the very least, she is a contagious, optimistic presence well worth experiencing.

At best, she may be a genius in her field that has discovered truly valuable information.

I learned how to fear nothing and to embrace the challenges I am faced with optimism and openness

Through performance mode lessons, Chrissellene has helped me build up my confidence and acknowledge my self-worth. These are lifelong skills that will always be a work in progress, and their mastery is a matter of practice and experience, but thanks to Chrissellene I now have the tools to hone them.

Chrissellene teaches Performance Mode and the 7 Commands, but I chose to work with her to build up my confidence.

After graduating from a university, I took a very demanding role which ultimately began to erode my self-confidence. I became increasingly more insecure and full of doubt and fear of how to manage my situation and find another job.

But thanks to Chrissellene I learned how to fear nothing and to embrace the challenges I am faced with, with optimism and openness. This fearlessness has given me the courage to take another job and move to a separate continent for it. Thank you Chrissellene!

Chrissellene and her teaching style are unlike anything I’d ever experienced before…

When I first came into the studio, I thought that Chrissellene would just be another vocal teacher, since I heard good things from other people.

I quickly learned, however, that her methods and teaching style are unlike anything I’d ever experienced before (in the best way possible). Of course, we worked on my voice, building good vocal habits, and doing her commands, which have truly helped me a lot vocally.

Read More

But more importantly, I’ve been exposed to what Chrissellene has dubbed performance mode, building my confidence, self-worth, and my ability to not take things personally.

I truly believe that this has helped me in every aspect of my life — not just with performance and my voice, but also with teachers, students, friends, parents, and simply being a human.

I think of Chrissellene as not just a vocal teacher, but also a mentor and a friend. I know that sounds cheesy, but I think that all of her lessons have changed my outlook on life and I couldn’t be more grateful!!!

THE Real Transformations from Scientists & Physicians

Real stories from scientists & physicians who elevated their vocal mastery.

The synchronized sound MRI of her voice is remarkable!

Ms. Petropoulos was recommended to me by a colleague because of her objective approach to voice lessons. I joined her studio shortly after she presented an abstract for The Voice Foundation. It was evident from the comments she received at that time that further objective evidence was necessary for her to validate her unique approach to singing.

By serendipity, we were just developing programs for magnetic resonance imaging (MRI) at the Washington Hospital Center to capture the physiology of cardiac muscle energetics, which required high-resolution images acquired over a short time interval.

Read More

It was also an incredibly fortunate coincidence that the physician in charge of the MRI program was an opera enthusiast. Thus, Chrissellene spent hours in the Magnet during off hours, when it was not being used for patients.

She sang; her husband recorded the sounds; and they documented, using videotapes, the anatomic and physiologic characteristics of her Commands of singing.

The MRI recording was transferred onto a digital tape prepared for recording sound. This video was taken to a professional recording studio, where Chrissellene had to dub her voice singing the scales in sync with the digital MRI.

She also has redone her Fiberoptic laryngoscopy with a prominent otolaryngologist in Washington, which documents the function of the vocal apparatus doing her Commands.

The final product, which resulted from hundreds, if not thousands of hours of labor, is an anatomic and physiologic basis for her Commands of singing. The ability to control those, which are usually autonomic functions, is of great interest.

As a scientist, I can appreciate that which she has documented. As a student, I am humbled by her ability to take a naïve, well-intentioned adult with no air, no vibrato, a closed throat and nasopharynx area, and no clue of remedy, to a sound that is much more appealing to me, my family, and my church congregation.

I would strongly recommend that you—and perhaps, some of your colleagues—spend the time previewing her presentation of the material cited above.

Performance Mode is the way to keep from getting emotionally involved with your performance. This allows you to not lose control of your autonomic nervous system. This is the physiological basis of the prevention of loss of neural pathways which constrict the body and throat.

As we speak and sing, we frequently overlook the complexities of our vocal apparatus. We focus on the sounds, intonation and content. Chrissellene G. Petropoulos has used the most modern imaging techniques to dissect the anatomic and physiologic characteristics of our vocal apparatus.

The synchronized sound MRI of her voice is remarkable. With her methods, we develop an understanding of that which we can control: posture, air flow, tongue, soft palate, throat, and neck positions. I, along with hundreds of her students, have learned her techniques and have effectively incorporated them into my daily public speaking and singing performances.

Chrissellene voice technique in our MRI shows all the proof one needs!

My name is Alexander S. Mark and I am the neuroradiologist who helped Chrissellene Petropoulos with her project.

I think this preliminary study opens many new research avenues in our understanding of the human voice and singing in particular. I think the MRI images themselves are compelling.

To my knowledge, this is the first such project which provides in vivo visual correlation between the anatomy of the vocal apparatus and the voice of a highly trained singer.

Read More

The MRI technique we used is available on all the current MRI systems. We used a 1.5T Philips Intera system and performed a series of very rapid acquisition images (approximately 1s per frame) through the larynx and palate and through the diaphragm. The images were then displayed as a “cartoon” in a cine mode providing the appearance of motion.

This is a similar technique to those used in cardiac MRI to visualize the beating heart or in other areas of the body where dynamic types of images are needed for diagnostic purposes.

The original part of the project was the synchronization of Chrissellene’s voice to the MRI images. The entire imaging procedure was videotaped and the various vocal Commands performed in the magnet were then repeated and synchronized with the dynamic MRI.

Ms. Petropoulos’s methods have been a lifesaver for me!

This note is a heartfelt testimonial to Ms. Chrissellene Petropoulos and her marvelous help to me.

I first met Ms. Petropoulos when, as a professional tuba musician, I was having trouble as I got older with my voice getting hoarse and raspy when I was playing tuba.

Being very concerned, I had doctors look at my throat but there was nothing wrong.

Read More

At about the same time, I saw a flyer for a clinic Ms. Petropoulos was giving at a church. The clinic described her Seven Commands to Vocal Mastery and said that her methods could guarantee speaking or singing clearly at any time just by commanding our bodies to move in certain ways. I went to her clinic and I was delighted to discover that her methods helped my voice.

The bonus feature was that her methods also helped my tuba playing!!! My phrases were longer and my sound was more sonorous and richer. My breathing was enhanced to use my full physical capacity. This discovery became the central point of my DMA Dissertation titled “A Physiological Exploration and Pedagogical Integration of Voice and Brass Tuba Physical Methods to Enhance Tone Timbre or ’Play Like You Sing”.

Since my interaction and lessons with Ms. Petropoulos, I have been able to teach her methods (with due credit to her) to my brass students. Some features such as 6 areas of inhaling, the tongue down, flat, and forward, holding our ribs out, and keeping our throat OHpen. These are easy for students to remember, give them better playing techniques instantaneously and are guaranteed to work when applied as a command to their body.

I have the highest recommendation that anyone wanting to improve their speaking and singing voice and physical parts surrounding those areas confer with Ms. Petropoulos and her Seven Commands!

Thank you so much Ms. Petropoulos!!!

Chrissellene helped me become a much better performer and teacher!

Chrissellene Petropoulos is an important teacher in my musical life, and her teachings have also been a valuable influence on my personal life.

When I met Chrissellene, I was already an established professional musician. Since earning a Doctor of Musical Arts degree from The Juilliard School, I performed throughout North and South America and in Europe and Asia. My students are among the highest achieving in the Washington DC metropolitan area.

With all of that, Chrissellene helped me become a much better performer and teacher. She was able to communicate specific aspects of breathing, and soft palate, tongue, and throat placement. In addition, her suggestions on phrasing, especially in using the breath to communicate musical ideas, have helped me and my students to become much better musicians.

Chrissellene has also helped me to understand the psychology of performing. I am much freer to accept criticism and to objectively address physical and personal issues in my playing. I am eternally grateful to Chrissellene Petropoulos for helping me grow musically and personally.
