He began his music career in the early 1970s with the group Os Lobos, recording the single "Fanny" on Top Tape before temporarily leaving music to pursue medical studies. In 1974, he launched his solo career with the single "Flash back" on Odeon Records. His breakthrough as a composer came in 1981 when his song "Bem-te-vi", co-written with Cláudio Rabello and performed by Renato Terra, sold over 250,000 copies. The following year, Dalto released his signature hit single "Muito Estranho" on EMI-Odeon, which sold over 500,000 copies, alongside his studio album Muito estranho (1982). In 1983, his song "Anjo", co-written with Rabello and Renato Corrêa, became a major hit when recorded by Roupa Nova, appearing on his second studio album, Pessoa (1983). His subsequent studio albums include Um coração em mil (1988) and Guru (1994), and his track "Faça um Pedido" was featured on the soundtrack for the telenovela Viver a Vida.
