João Victor Ferreira Silva, 13 years old, from Abadia de Goiás, in the metropolitan region of Goiânia, impressed the internet by adapting a guitar. The boy shared on social media how he tuned the strings of the instrument so that they made the sound of a viola. Ícaro, from the duo with Gilmar, gave a guitar to João Victor as a gift and published it on social media (watch above). The singer published the video last Friday (12). Ícaro said that, after seeing João Victor's video, he remembered when he was younger and wanted to learn to play the viola and tuned the guitar strings just like the boy. So, the singer wanted to give him a guitar. In the caption, Ícaro highlighted that João Victor is a talented boy and could become a very successful multi-instrumentalist. The singer also wrote that João serves in the church and has a very humble family.

"I took the mizona (sixth string of the guitar), completely detuned it to take it off the axis, then I removed it. I kept these two strings in normal guitar tuning and the other three bass ones I tuned, I think, one tone lower. And now... I have the sound of the viola on the guitar", said João. The mother played with her son and said that “Now NASA is coming”. The video has almost 6 million views and more than 100 thousand shares. In the publication, in addition to comments from the duo Ícaro and Gilmar, a music teacher offered free lessons to João. Singer César Menotti replied “beautiful thing” when an internet user tagged him.
