Timbre/Instrumentation

What will be an ideal response?

(Include the Quichua name of each instrument and its classification, plus the definition and classification of a musical triangle.)
• An ensemble of bamboo panpipes of different sizes (zampoñas in Spanish) plays the melodies. The performers (Kallawaya people) also dance in a circular pattern as they play. During the rainy season—November through late February—instead of panpipes, the Kallawaya play transverse flutes or duct flutes that are respectively similar to Western silver flutes or recorders.
• panpipes are aerophones (wind instruments—vibrating columns of air produce their tones)
• Double-headed drums (wankara) playing a heavy, steady beat and a triangle (ch'inisku) accompany the music.
double-headed drums are membranophones (vibrating stretched skins produce their tones)
• A triangle is a musical percussion instrument made of a metal rod bent into the form of a triangle. The instrument is usually played by being struck or hit with a metal "beater" (rod).
• A triangle is therefore an idiophone—from "idio," which means "one's own"--because the vibration of the instrument itself (its constituent material) produces its sound. Other familiar examples of idiophones are the gong and cymbal.
