Especially during the rainy season, when, due to the bad weather conditions, the possibilities for outdoor sports activities are rather limited, the children dedicate themselves to music. Consequently, the Casa Hogar also has its own rock band whose programme does not only consist of cover songs, but also of songs written by the band members themselves. The same people make up a folkmusic group. The typical Guatemalan instrument, the Marimba, and an authentic Latinamerican instrument, the Andina, create the musical frame for particularly solemn events and celebrations at the Casa Hogar. Moreover, some of these boys who play in both groups attend the academy of music every week to be trained professionally on their instruments there.
