Define sanjuán, including its preferred performing instrument, isorhythm, and why walking is so important to the Cotacachi Quichua

What will be an ideal response?

• A sanjuán is in recurring eight–beat phrases often with a short-long-short rhythmic marker and made up of isorhythmic patterns (the second half of a phrase has the exact same rhythm as the first half of the phrase).
• "Today, the instrument that Cotacachi Quichua often use to perform sanjuán is the harp without pedals [called a "diatonic harp"] . . ."
• Having few motorized vehicles or roads, most of the Quichua rely on walking the ubiquitous footpaths found throughout the area. Walking therefore is a very important aspect of their life and culture.
