Garoto
Aníbal Augusto Sardinha, known as Garoto ('The Kid'), was a Brazilian multi-instrumentalist and composer who was already a working guitarist and banjoist in São Paulo dance bands by his early teens. Through the 1930s and '40s he fused Brazilian choro with the chromatic harmony he heard in American jazz and in Django Reinhardt's records, producing a body of solo-guitar choro compositions — 'Jorge do Fusa' foremost among them — that anticipated bossa nova's harmonic sophistication by more than a decade before his early death in 1955.
Biographers of Garoto note plainly that he 'was influenced musically by Reinhardt' — the Belgian-Romani guitarist whose Quintette du Hot Club de France records were circulating internationally by the mid-1930s. Reinhardt's chromatic, jazz-harmony vocabulary laid over a string-band context gave Garoto a model for pushing Brazilian choro's harmony somewhere denser and more chord-adventurous than its turn-of-the-century roots, years ahead of bossa nova doing the same thing with samba.
listen forPlay Reinhardt's 'Minor Swing' — that restless minor-key chord climb under a spry melodic line — then Garoto's 'Lamentos do Morro.' Listen for the same instinct: a folk-adjacent tune harmonized with jazz's harder edges instead of simple triads.
