Found the official music sheet of the first Bossa Nova: Chega de Saudade!
Chega de Saudade is considered the song that initiated the bossa nova movement. It was composed by Tom Jobim & Vinicus de Moraes and released in the album Canção do Amor Demais (1958) by the singer Elizeth Cardoso. However, the song gained popularity with the Joao Gilberto’s recording released a few months later. In this recording he sings and plays acoustic guitar introducing the bossa nova beat, which became an essential feature in the bossa nova rhythm.
