Dercio Rocha Marques (Uberlândia, August 19, 1947 – Salvador, June 26, 2012) 

was a Brazilian guitarist, singer, performer and composer.

This academic work was carried out based on the lyrics of the singer's songs, which are extremely imaginary and fanciful.

Why just listen to the songs? It was this question that made me think of this interactive kit for children aged 03 to 7 years.

The illustrator of the book are the children themselves, who after drawing are free to erase and redo the drawing on the transparencies contained before each stanza of the song. The book comes in a kit, which also contains a CD with songs by Dércio Marques and a set of pens for the illustrations.
