In July 1958, Elizete Cardoso released the famous LP, Canção do Amor Demais, containing songs by Tom Jobim and Vinicius de Moraes. The record, however, would enter the history of Brazilian popular music for another reason: Gilberto accompanied Cardoso on guitar on the tracks "Chega de Saudade" and "Outra Vez", these being the first recordings of the so-called "bossa nova beat". In August of that year, Gilberto released a 78 rpm record containing "Chega de Saudade" and "Bim Bom", recorded at Odeon, with collaborations from Jobim, Dorival Caymmi, and Aloysio de Oliveira. This album inaugurated the "bossa nova" genre and soon became a commercial success. Gilberto's recording had arrangements by Jobim and the participation of Milton Banana, among other artists. Gilberto innovated by using two microphones to record, one for the voice and one for the guitar. This way, the harmony became more clearly heard. Until then, songs were recorded with only one microphone, emphasizing the voice to the detriment of the guitar. With this innovation, voice and guitar could compete equally, if the voice maintained a natural intensity. Thus, it was necessary to issue the voice in a volume close to that of ordinary speech. With Gilberto, voice and guitar are kept at the same volume intensity, with the microphones picking up both sound sources equally, and, if required, changing the volume of both would be in equal proportion. In 1959, Gilberto released another 78 rpm, containing "Desafinado" by Jobim and Newton Mendonça, and "Hô-bá-lá-lá", written by himself. In March 1959, he released the LP Chega de Saudade, which became a sales success and had a major impact in the history of Brazilian music.
