Voted Best Singer of 2019 by the now-defunct Brazilian classical music website Movimento.com for her performance as Vanessa in the opera of the same name in Guarulhos, Tati Helene has worked with important names in the European opera scene. Highlights include stage directors such as Peter Konwitschny, with whom she performed Salome on tour in Switzerland; Bepi Morassi, in a Teatro La Fenice production in Venice (where she portrayed Rosa in Britten’s Il Piccolo Spazzacamino); and Stefano Vizioli, in the São Paulo production of Falstaff at Theatro São Pedro (as Alice Ford). She has also collaborated with conductors like Austria’s Michael Radulescu (as soloist in Bach’s Cantata 110) and Alessandro Sangiorgi, an Italian based in Brazil (with whom she performed as Mercedes in Carmen at Teatro Guaíra in Curitiba and Norma in concert at the same venue).

During the years she lived in Italy, Helene was a scholarship holder of both the Italian government and the Conservatorio Antonio Buzzolla while pursuing her Master’s degree in Opera Performance. She performed on some of the country’s main stages, including the Teatro Malibran in Venice, Teatro Comunale di Rovigo, and Teatro Olimpico di Vicenza.

In Brazil, she was twice invited to share the stage with major opera artists in the Grandes Vozes project: first with baritone Renato Bruson and later with mezzo-soprano Graciela Araya, both performances receiving critical and public acclaim.

She participated twice in the Opera Festival of Theatro da Paz, singing Salome and later Senta in Der fliegende Holländer, the first Wagner opera ever staged in the city. Again as Senta, she performed at Palácio das Artes in Belo Horizonte in 2018. At the end of 2013, she was called—on the very day of the performance—to replace soprano Eliane Coelho in the demanding title role of Cherubini’s Médée at Theatro Municipal do Rio de Janeiro, with the OSB conducted by Argentine maestro Carlos Vieu. Back at the TMRJ, this time sharing the role with Coelho, Helene sang the Foreign Princess in Dvořák’s Rusalka in 2024, and in 2025 she starred in Lehar’s operetta Die lustige Witwe.

Her performance in La Voix Humaine, directed by Roberto Alvim, also earned her wide critical acclaim, following a three-year tour with performances in Guarulhos (2015), São Paulo (2016), and Rio de Janeiro (2017)—with her appearance at Sala Cecília Meireles being voted one of the best of 2017 by Movimento.com.

She has led several Brazilian premieres: Monteverdi’s L’incoronazione di Poppea (at the Rio de Janeiro Planetarium, 2014), Barber’s Vanessa (2019), Menotti’s The Consul (2020), Rossini’s Il Turco in Italia (2021), Dvořák’s Rusalka (2021), Hindemith’s Das lange Weihnachtsmahl (2024) at Teatro Adamastor in Guarulhos, and the world premiere of Martinelli’s O Peru de Natal, as Maria Luísa at Theatro São Pedro (2019).

Helene also stands out as a symphonic soloist. She has performed in Brazil, Uruguay, and Italy in works such as Leandro Alvarenga’s Missa for Two Solo Voices, Choir and Orchestra (written especially for her), Schubert’s Messe in G-Dur, Fauré’s Requiem, Vivaldi’s Magnificat and Gloria, Jommelli’s Veni Creator Spiritus (Brazilian premiere), Mendelssohn’s Lobgesang, Mozart’s Vesperae Solennes de Confessore, Mahler’s 2nd and 4th Symphonies, Ravel’s Scheherazade, Dvořák’s Te Deum, Berlioz’s La mort de Cléopâtre, and Beethoven’s 9th Symphony. She was also featured in the 2014 Brasília Opera Festival singing Strauss’s Vier letzte Lieder.

She holds a Master’s degree in Opera Performance from the Conservatorio Antonio Buzzolla in Italy, a Bachelor’s degree in Vocal Performance and in Physiotherapy, and is also a professionally trained actress, graduated from the William Shakespeare College. Her voice teachers include Heloísa Petri, Carmo Barbosa, António Garófalo, Luisa Giannini (Italy), and Dr. Emilio Pons (NY). Always seeking artistic growth, she has taken part in numerous masterclasses with distinguished opera legends such as Fiorenza Cossotto, Silvia Sass, Jaime Aragall, Mara Zampieri, Maria Pia Piscitelli, Teresa Berganza, KS Edda Moser, KS Thomas Moser, KS Karan Armstrong, Chuck Hudson, Denis Combe-Chastel, Angelo Raciti, Martin Struckmeyer, Janet Williams, Petra Lang, Carlos Montane, and Olga Mykytenko.

She was awarded First Prize at the Bianca Bianchi Competition in Curitiba (2002), selected in the Audiciones Nuevas Voces Líricas at Teatro Colón in Buenos Aires (2008), and recognized as a promising Wagnerian voice at the Brazilian auditions for the International Richard Wagner Competition (2009).
