Which of the following is a side-blown cane flute played year-round?

The side-blown cane flute played year-round is known as the Siku. This traditional musical instrument is particularly associated with the Andean cultures of South America, specifically in countries like Peru and Bolivia. The Siku is crafted from bamboo or cane, and it is designed to be held horizontally while the player blows air into one end to produce sound.

Its year-round usage highlights its importance in cultural festivities, rituals, and everyday music. The Siku is often played in groups, which contributes to its popularity in communal settings and celebrations, reinforcing social ties and cultural identity.

In contrast, the other instruments listed are not categorized as side-blown cane flutes or do not possess the same year-round significance. The Tarkas, while similar in tradition, can vary in format and isn't recognized as a primary flute type like the Siku. The Ocarina is a陶器based wind instrument with a different structure and is not made from cane. The Rasp, typically made from metal or another hard material, is used for creating percussive sounds rather than for melodic playing like that of a flute. This distinction reinforces the unique nature and cultural relevance of the Siku in musical traditions.
