What is the Flamenco Farruca?
The flamenco Farruca, thought to originate in Galicia, Spain, was traditionally danced by men with no singing component. Travelers to the Andalusian region were called farrucos, so this is likely where the Farruca palo name came from.
The Farruca is usually played in A minor, with a compás of two measures of 4/4 time signature with accents on beats 1, 3, 5, and 7 as seen here:
