A musician on the sidewalk

This gentleman is a musician who hangs out in the Recoleta area. At least on one day when we were walking by, he was in that area near the sidewalk by the cemetery. And as a musician, he plays music. What caught our attention and was interesting is the instrument he uses—interesting because of how original it is. It is handcrafted, or at least that's what it looks like at first glance. And he makes it play nice melodies of well-known songs. He plays for tips (a la gorra): instead of passing a hat around, he has an inverted tambourine available where people leave him money. He is well worth listening to for one, two, or more songs. The instrument is made of PVC tubes, meaning plastic pipes, each with different measurements and lengths. He has attached a metal cymbal, like the ones used in drum kits, to one of his feet. Underneath his seat, he has placed a sort of bass drum. This percussion instrument requires a drumstick or mallet to strike it and thus produce sound. He made this drumstick or mallet out of the handle of a mini umbrella. At the same time, he attached a set of chajchas—an ancestral instrument made from goat hooves—to the mallet, so that every time he hits the bass drum membrane, the chajchas also sound, generating a new and unique sound. He plays the plastic tubes using a plastic paddle at the same time as his free hand. In addition to the talent for bringing out the melodies, he is ingenious.
