João Gilberto was born in Juazeiro, Bahia, the son of Joviniano Domingos de Oliveira, a wealthy merchant, and Martinha do Prado Pereira de Oliveira. He lived in his native city until 1942, when he began to study in Aracaju, Sergipe, returning to Juazeiro in 1946. At the age of 14, Gilberto got his first guitar from his grandfather despite disapproval from Gilberto's father. Still, in Juazeiro, he formed his first band, called "Enamorados do Ritmo". Gilberto moved to Salvador, Bahia, in 1947. During his three years in the city, he dropped out of his studies to dedicate himself exclusively to music and at the age of 18 began his artistic career as a crooner at the Rádio Sociedade da Bahia.
Gilberto's first recordings were released in Brazil as two-song, 78-rpm singles between 1951 and 1959. In the 1960s Brazilian singles evolved to the "double compact" format, and Gilberto released some EPs in this new format, which carried four songs on a 45-rpm record. In 1956, he returned to Rio and struck up old acquaintances, most significantly with Antônio Carlos Jobim, who was by then working as a composer, producer, and arranger with Odeon Records. Jobim was impressed with Gilberto's new style of guitar playing and set about finding a suitable song to pitch the style to Odeon management.
In 1963, Gilberto collaborated with American jazz musician Stan Getz on the album Getz/Gilberto which was released the following year. Jobim played the piano for the album while Gilberto's then-wife Astrud performed the vocals in English while he sang in Portuguese. Although Astrud Gilberto was only in the recording studio to be with her husband, João Gilberto requested her to sing on several of the tracks as he could not sing in English.This resulted with a duet between the two on the track "The Girl from Ipanema" which became a major hit from the album. At the 7th Annual Grammy Awards, Getz/Gilberto won three awards including Album of the Year, which marked the first time a jazz album received the accolade.
Gilberto was known for his demanding acoustic and noise-control standards. During a recording session of the song "Rosa Morena", he insisted on 28 takes to get the pronunciation of the o in "Rosa" just right. Nonetheless, despite his high acoustic standards, he skipped a contractually required sound check prior to a July 2003 performance at the Hollywood Bowl, in Los Angeles. This negligence (and the ensuing sound fiasco) prompted the audience to stream from the venue before the concert ended. In 1997, Gilberto sued record label EMI over their reissue of several of his early works, which he contended had been poorly remastered. According to The New York Times, "A statement by his lawyer at the time declared that the reissues contained sound effects that 'did not pertain to the original recordings, banalizing the work of a great artist." Following the incident, EMI ceased production of the albums in question, and, as of 2008, the lawsuit was yet to reach a decision.
In 2000, Gilberto won the nomination for the Best World Music Album category in the 42nd Annual Grammy Awards for his work in the album João Voz e Violão. A year later, he was inducted into the International Latin Music Hall of Fame.
On September 2003, Gilberto performed four shows in Japan. His performance at the Tokyo International Forum on 12 September was recorded for a live album titled In Tokyo which was released in 2004. At the 6th Annual Latin Grammy Awards in 2005, In Tokyo received a nomination for Best MPB Album. On 17 May 2017, Gilberto received an honorary doctorate in music from Columbia University but did not attend the commencement ceremony.
Role in bossa nova
With the introduction of the microphone and the amplifier in Brazil, Gilberto realized that the sound source did not need to be emitted intensely, regarding the voice and instrument, which favored subtle and internalized interpretations. On the other hand, at the time of the first "bossa nova" recordings, Brazil still did not have hi fidelity recording equipment capable of reproducing more complex sonorities. Due to that, Gilberto and Tom Jobim, Gilberto's first arranger, elaborated complex harmonies under the influence of American music, and at the same time they simplified the general sound, because of the equipment limitation.
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 colaborations 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.
