FAQ: Frequently Asked Questions
Is any type of wood suitable for making a viola?
No. The secret lies in light woods like ximbuva or white fig. They are easy to carve and offer the dry resonance that Cururu requires.
Is the viola de cocho tuned like a guitar?
Absolutely not. She uses her own tunings, such as the "canotio," where the strings don't follow an ascending order of pitch. This gives the instrument that characteristic, "jumbled" sound.
Is it difficult to find the instrument to buy?
Authentic instruments are custom-made by master craftsmen in cities like Poconé and Várzea Grande. What you find in souvenir shops is usually just decorative.
Why doesn't it have a hole (mouth) in the center?
The absence of a soundhole is a technical choice: it concentrates the sound within the hollowed-out body and leaves the soundboard free so that the musician can drum without fear of breaking the instrument.
Does the dusky-faced parakeet have any connection to the instrument?
Not directly, but both are symbols of preservation in the Pantanal. Just like the bird, the viola de cocho requires a healthy ecosystem and local culture to survive.
