The levered harp as played in Paraguay , Combia, Peru etc is a diatonic instrument tuned to a fixed initial diatonic scale, bu during the playing ofthe song some levers are move to provide one or more of the 5 chromatic or "blue" note that extend the 7 notes of the diatonicscale to the 12 of all notes. In particular
we have the 5# chromatic note , for harmonic minor ofthe aeolina mode shifts, the 2# and 5# for double harmonic minor shifts ofthe aeolina mode, and slso 4# and 6# for chromativ shifts as in the overtones diatonic scale of the brass instrumenst between 8th and 16th overtones. Finally the 1# also for neopolitan shifts of the aeolian mode.
Thus the practice o the leverd harp in the latin americacountries realizes what we have describe here as chromatic tonality in the posts 336, 334, 263, etc
