What type of flute is characterized as a vertical duct flute with a recorder-like mouthpiece used during the rainy season?

The correct answer describes the Tarkas, which is indeed a vertical duct flute recognized for its recorder-like mouthpiece. This type of flute is often associated with various South American musical traditions and is particularly notable for its use in outdoor settings and during specific seasons, such as the rainy season. The design of the Tarkas allows for a unique timbre that complements traditional music and cultural celebrations, making it integral to the musical landscape in regions where it is played.

The other options represent different types of instruments or musical groups. The Huehueti is a type of drum, specifically a large, ceremonial Mexican drum used in dances and rituals. Quenas are a different type of flute that are also popular in Andean music but have a different construction and playing style, lacking the specific characteristics of being a vertical duct flute with a recorder-like mouthpiece. Mariachi refers to a style of music and the ensemble that plays it, which typically includes violins, trumpets, and various guitars rather than focusing on a specific type of wind instrument like the Tarkas.
