“I have had the great pleasure of working with Maestro de Oliveira on a variety of repertory of the operatic canon. He is very knowledgeable about every musical style and language, and he has ears of gold. I trust him to keep my voice in line, and to encourage the freest approach to dramatic repertoire with flexible lyric and beautiful sound.”

“Teachers like Mozart are endangered species. Mozart possesses great understanding and knowledge of vocal technique and pedagogy that is rooted in the golden age Italian style of vocal production and its crucial role in the matters of musicianship, language, style and serving composer’s intent. Mozart’s greatest strength is in his “ears”, his ability to detect and address student’s vocal issues and challenges and successfully guide them through recovery into vocal freedom. I prepared over 10 full roles with him for which I received important accolades. I owe much of that success to him.”

Jasmina Halimic | Soprano

“In order to get better as an opera singer, I need a teacher with a musically-trained ear, sensitivity to voice and body function, and knowledge in technique and style. Mozart possesses all of these and more. Working with him gave me the tools to face my difficulties and get immediate results, allowing me to do my best on stage. I'm thankful to him and can't wait for our next session.”

“Mozart de Oliveira is a brilliant technician with extremely discerning ears. His process is detailed and methodical and his ability to deliver anatomical explanations to singers is one of his greatest assets. He builds and nurtures voices with such insight, sensitivity and precision. His breadth of knowledge regarding style and repertoire is vast and he understands the intense demands of the business. Mozart’s unique teaching style is challenging, supportive and encourages responsibility and ownership of the technique.”

“For me, Mozart — and the experience of working with him — can be described succinctly in the word INTEGRITY. When I work with Mozart, I have a calmness about me because I know I can rely on him to demand excellence musically through his high standards, as well as coax out my vocal potential through patience and encouragement. Mozart is able to balance genuine care and compassion with a no-nonsense attitude. I will say that at the heart of it all lies Mozart's undeniable passion for singers and singing. I recommend him to professionals at all levels.”

“I had an amazing experience working with Mozart as I prepared to enter Guildhall. Not only does he know so much about technique, but he also has an amazing ability to explain his technical and musical ideas, so the student can genuinely understand and assimilate them. Mozart is so professional, as well as very patient and kind. He helped me so much, especially with my upper and lower extension. I made huge progress throughout my lessons with him.”

“As a tenor with eight years of working with several teachers, I had been struggling first with consistency in my vocal technique and secondly with singing in full voice above a G#4. Thanks to Mozart's instruction, today I feel secure in terms of technique and in terms of being able to sing in full range with agility, brilliance and stamina. I highly recommend Mozart to any serious singer who wishes to advance their studies towards a professional career in singing.”

Yonathan Suiss | Tenor

“I was having trouble choosing my repertoire until I found Mozart. Once we selected the right music for my voice type, he perfected my breathing technique, the use of my body and singing positions. All together, Mozart has made such a great contribution to my singing. I highly recommend him.”
