Often called just Tico Tico, written by Zequinha de Abreu in 1917. I tried to learn the excellent version by Paola Hermosín found here: • Tico-Tico no Fubá para Guitarra but I'm not really a classical guitar player so I had to change some fingerings and rely on hammer on/ pulloffs more than a classical player would (as well as using thumb pick and electric guitar). It has sections in A minor, A major, and C major. Some versions of this go to the C major section after the first theme, others put the A major section there (as in this version).
