Merging centuries of vocal wisdom with the best of contemporary knowledge.

In our modern world, there are all kinds of wonderful genres and styles of music and spoken word to enjoy - some more vocally challenging than others. It can sometimes be difficult to nurture our creative, musical and verbal expression while at the same time, maintaining a strong, healthy, beautiful voice.

The Vertical Voice Vocal Training Method is a foundational vocal technique that if implemented well, can facilitate the development of a lifetime of nearly limitless vocal access. Through it, Diana Grasselli has found ways to communicate time-tested techniques and concepts in a modern and easily accessible context so that anyone can learn to sing or speak in efficient, effective, expressive and uniquely personal and authentic ways.

The Method offers a direct, systematic and proven process for singers, speakers and voice professionals of all styles, genres, ages, levels and disciplines to strengthen, align, balance and beautify their vocal instruments while simultaneously improving confidence, authenticity, expressiveness and sustainability. 

With a vast body of knowledge, education and experience, Diana Grasselli has effortlessly combined her technical understanding of the vocal mechanism with her real-world experience in multiple contemporary and classical styles. Possessing a rare ability to bridge the gap between pure vocal technique and contemporary music forms, Diana created The Vertical Voice Method in order to help others do the same.

Reviews and Testimonials

  • "I started taking lessons with Diana almost 3 years ago, and it is a decision that I am incredibly glad I made. I was very nervous at first, having gone in as an adult with no singing background, but Diana immediately creates a space that feels comfortable, for even the most anxious of people. I didn't really know what to expect when beginning and felt skeptical of the amount of improvement my voice would be able to make, but over the last 3 years I have constantly been able to feel progress. My skills and technique have improved greatly, as has my confidence, which starts vocally but ultimately impacts my overall sense of myself. Diana is an incredible vocal coach who can improve any voice, as well as a very genuinely kind and empathetic person, which is a combination that makes it feel comfortable to be vulnerable, to challenge yourself, and to allow room for both growth and mistakes. I am so grateful I have had the opportunity to work with her and be able to feel all the positive effects that singing can bring to your life."

  • "My thoughts about The Vertical Voice Method!!: I am the Lead Singer for The Maeflies band. My voice was unreliable at gigs, making me unconfident and distracted on stage. My voice felt damaged, tired and was hoarse after every performance. I started taking lessons from Diana Grasselli due to my vocal concerns. Within six months of vocal lessons, addressing prohibitive speech habits and following Diana’s Vertical Voice practices, I began to notice significant improvements. I am a natural Contralto. I was forcing my voice to sing songs in Keys that did not complement my voice. She guided me (and my band) to always write and choose song material that is best for my voice. I learned to adjust my range. I improved my posture along with my physical and vocal alignment. I learned to blend my chest and head voice. I improved my breathing and learned to use my voice without straining it.

  • "Through years of working with Diana, she helped find the right home for my voice. Now, my voice feels authentic, free and resonant. I am confident on stage and know I can rely on my voice 100%. My voice will not fail me as it once did. Diana and her Vertical Voice practices transformed my voice. I will continue to follow Diana’s practices for as long as I am a singer. I am grateful for finding Diana. Her vocal technique works AND she is a beautiful person inside and out."

  • "Diana worked with our daughter for a number of years. Not only is she extremely talented, Diana is a professional that brings a unique perspective in developing young talent. Aside from being a kind and compassionate person, it was clear that she always had my daughter’s best interest in mind…. And heart. Diana’s support and development extended long after my daughter left the studio and she was instrumental in helping Paige navigate a path in her musical career."

    - Chris Parrucci

  • “Taking lessons with Diana has been a transformative experience for me, both as a musician and as a person. I enjoy the lesson experience with her, and always have new and exciting concepts to engage with throughout the week. I began lessons while working on a debut album, and specific instructions from Diana's TVV method have led to tangible improvements in my sound production, emoting abilities, and the overall communicative power of my voice. Now, what I thought was a liability to my album has become a strength! I highly recommend choosing Diana and the TVV method!"

    - Dr. Spencer Miller

  • "My experience with Diana and The Vertical Voice method has been incredible. Having tried other coaches and methods for learning to sing before, this is the first time I’ve felt that I was learning from someone with a complete and structured plan. With Diana’s TVV approach I went from 2 octaves to 3.5 octaves in range and developed depth of tone, character, and emotion in my singing voice. I can’t recommend this approach enough, especially for those who have struggled to find their way in singing before."

    - Colton M.

  • "I am truly grateful for the time I have been able to spend working with Diana and the TVV Method. I compose my own music and wanted to improve my vocals to a place where I could produce the quality of sound I desired before recording my songs. Not only did my confidence with my vocal abilities improve, but I was able to integrate the knowledge into my body's memory very quickly. Diana is a truly gifted teacher with the ability to transfer a complex body of knowledge to her students. Her strong developed intuition and technical knowledge about the voice allows her to describe in detail at any given point what is happening. Her level of expertise surpasses most in her field and anyone who has the chance to study with her using the TVV Method will not regret it!"

    Part I - Molly H.

  • “Every time I work with Diana she instantly puts my voice in a safe, comfortable and expanded place. I always come out of lessons with hope and excitement for my voice. The method she created is so carefully thought out, how our voices work and how to properly support and build them in a sustainable way. I’m always amazed Diana pinpoints exactly what adjustment needs to be made to open up my voice, no matter how subtle. I feel so confident and capable under her wing and I know I will reach my fullest potential with her guidance."

    Part II - Molly H.

  • “When I first began my vocal training with Diana, I was unaware of all the techniques required to sing. All I knew was just singing without the proper usage of my voice. Diana has continued to be patient with me while I discover my true potential in singing. All of her advice and strategies has made it easier to access my singing skills. She is incredibly talented and grounded. I enjoy being one of her students and getting the opportunity to learn from her. Thanks to Diana for helping me unlock a new set of skills when it comes to singing. This will benefit me long term. I am so thankful."

  • “Diana not only is a great vocal coach, but she instilled confidence in me and taught me techniques for recording, both of which were instrumental in launching a professional career." -

    - Andy Steinfeldt

  • "My daughter, ‘A’ began as a student with Diana Grasselli in September of 2019. Over the time, Diana helped ‘A’ discover and refine her vocal talent through the course of musical exploration that ultimately led to a greater appreciation of music and its totality of expression. The past five years have been extremely challenging for our family. Notwithstanding Covid 19 and the financial duress that ensued, Diana’s steady influence over my daughter remarkably endured. Her experienced, transformative presence provided the terra firma upon which ‘A’ gained confidence in her voice and the power of music to mitigate emotional struggle. I am forever grateful, Diana. In the turbulent life of a 13 year old girl, you made a positive difference. And continue to do so every Sunday right around 11:00 am. Thank you isn’t a big enough phrase to express my gratitude. Nevertheless, thank you. Thank you, thank you, thank you." - Will R.

  • "I worked with Diana for a couple of years and transformed from someone who was shy about using their voice to understanding my instrument, how to warm up, how to pick songs that will work and pick the right key in which to sing them. She is so knowledgeable and compassionate and I always felt comfortable even when I felt challenged. Warming up using the Vertical Voice Method really opened up my ears and trained my body to recognize when I was making a clear, correct, and musical sound. I would recommend her studio and book to anyone, newbie to professional, looking to move their singing to the next level."

    - George C.

  • "Learning about the various internal “systems'' that go into making my voice work has been a priceless experience. Understanding how to “listen” to my body and to adjust each of these systems to produce the best vocal sound possible has been such an eye-opening experience. Building my voice from the top-down has been so counterintuitive, but I trust Diana and her process fully as I am starting to see and experience the results The Vertical Voice promises. TVV has taken the guess-work out of singing for me and how to train/prepare. I now know how to use tools in my vocal toolbox that I never would have known I had, and have many more to add. Very grateful for TVV and this process."

    - Brett J

  • "My daughter studied voice, piano technique and songwriting with Diana for about 6 years. She knew she wanted to become a songwriter and was supported in reaching those goals through classical methods and the Vertical Voice techniques in fun and engaging ways. When it came time for her to prepare her college application portfolio, she was supported and encouraged in ways that allowed her to be both focused and motivated to reach her goals (which she did, getting accepted into her top choice college)! As a parent, I always felt respected when it came to communication about my daughter's progress. I am wholeheartedly grateful to Diana Grasselli for her expertise, professionalism and candor."

    - Julie

  • "I had a great experience working with Diana and the Vertical Voice Method. The book is full of many exercises that will help bring out your best singing. One thing that I have consistently used since working with Diana and the TVV method is the oo-tube idea, which has helped me modify vowels or words that have been tricky to sing. Diana always encouraged me to produce a smooth ribbon of sound, which is an idea I often go back to when working on my singing."

    - Matt Hannah

  • "Before I started lessons with Diana a couple of years ago, I used to tell people that I didn't play an instrument but that I loved to sing. Diana has taught me so much through her Vertical Voice techniques, helping me reach new vocal ranges that I never dreamed I was capable of ~ and to recognize that my voice IS my instrument. Through her compassion and intuition gleaned from decades of her own incredible experience, Diana has guided and encouraged me, inspiring me to write more songs and show me that the one I wrote many years ago wasn't "accidental" as I thought it to be. I consider her my mentor and dear friend, and I am forever grateful to her and for her."

    - Kat Moore, Artist & Activist

  • "My experience working with Diana and The Vertical Voice was amazing. She stretched and strengthened my voice to perform in ways I would not have thought possible. I am confident singing soft tender ballads to harsh, aggressive hard rock lyrics with distortion. Unlocking the potential has been amazing and the technique keeps my voice safe. Thank you for the gift you helped me unlock."

    - Rich

  • "Diana brings nuanced artistry, technical mastery and uplifting encouragement to her vocal instruction. She helped me improve my technique and build my performance confidence when I needed it most. I'm so grateful to have learned from her personally and the TVV exercises have been a pillar of my vocal practice for many years."

    - Allison LaBonne (Typsy Panthre, The Owls, The Starfolk)

  • "Working with Diana was amazing. She helped me to understand music and my way of singing changed. Diana is a good teacher and she is patient and understanding. Since Diana step in my life as my Coach my voice and my singing changed completely. Thank you Diana. I will still choose you as my Coach." - Sarah Mwakana

  • "I met Diana 25+ years ago in Minneapolis, MN, through a little ad in the newspaper. From day one there was a connection. I felt that I had met a kindred spirit. We worked together in Minneapolis for several years, during which she taught me so much about my voice, always encouraging me to step out of my comfort zone and be confident in my singing ability. She does that with all of her students. Her motto is that everyone should be singing...it's good for the soul. After marrying and having my daughter, we moved to Phoenix so I had to put my lessons with Diana on hold for many years. Several years ago she started giving virtual lessons so fortunately, I was able to continue working with her! I also signed up my daughter for lessons as she is very passionate about singing. She is now 16yo and during the two years she has been taking lessons with her, her voice has blossomed into a round, full voice instrument with beautiful tone. I would never have trusted anyone else but Diana with my daughter's voice and The Vertical Voice Method." - LeAnn C.

  • "Diana is an amazing person, both professionally and personally. If any person, regardless of age or perceived ability, wants to learn how to sing or expand their voice (she works with public speakers as well) to limits you did not even know you could achieve, Diana is the best there is and you will be amazed by the transformation of your voice and confidence levels. She’s had a very successful career in all aspects of music: singing, performing, songwriting, recording, producing, etc. and has done so all over the world with established, well-known artists, writers and producers. Additionally, she has had students compete on The Voice, coached artists through record sessions, etc.. With her vast array of experiences, she can help anyone achieve whatever goals they are motivated to reach.

  • Diana is an invaluable resource for anyone looking to transform their voice. She is an expert teacher who has truly enriched my life, and I cannot recommend her enough.

    Emma K.T.

  • Diana has an uncanny gift of hearing and working out the adjustments your voice needs in order to sing with alignment. I have always struggled with the passaggios in my big singing voice, but after three years of study with Diana, my breaks have all but disappeared. Whatever energy I bring to a lesson, she doesn’t let me get away without doing my best, and after an hour I feel filled with her encouragement..

    Kate Jennings

  • My voice lessons with Diana have felt transformative. Through her integrative approach to vocal instruction, she has offered valuable technical insight and feedback. Not only has she encouraged me to live into to my vocal mechanism, but to whole self.

    Elizabeth Giffin

  • “Diana Grasselli is an amazing, knowledgeable and gifted vocal teacher. She gives 200% to all of her students and under her instruction my daughter ‘s vocal range, technique, confidence and stage presence has blossomed. We feel very blessed that our daughter has had the opportunity to work with Diana.”

    Sophie Fawcett Peters

  • “While on a two-month work assignment in the Minneapolis area, I decided to take voice lessons with Diana. It was my first time and I can honestly say that I will never forget the wonderful experience. After each lesson, I found myself literally counting down the days until the next. I learned more about my own voice in two months than I had in my entire life. She is truly a blessing and just an absolute blast to work with, I would recommend her to any singer wanting to learn how to become better at what they do”.
