Swiss clarinetist Gilbert Favre helped found a folk music group in this region, for which he played an instrument called the qina. An hour-long cycle subtitled "A Song of Love and Death" intersperses folk music from this region (10[1])with the mythology of Tristan and Isolde and was composed by Olivier Messiaen. A string orchestra "Walkabout" inspired by the music of this region was composed by Gabriela Lena Frank. The soulful harawi genre was developed during an empire in this region, whose ancient k'antu style made use of a siku panflute. A folk song from this region inspired a zarzuela that includes the song "The Condor Passes" by Daniel (10[1])Alomía (10[1])Robles. A lute from this region called the charango was traditionally made with the shell of an armadillo. (10[1])For 10 points, name this region whose Quechua and Aymara music took inspiration (10[1])from the Inca. (10[1])■END■ (10[2]0[2])
