Le mystère des voix bulgares : volume 2

Balkan music is a broad umbrella for the traditional and popular musics of the Balkan Peninsula, characterized by asymmetrical (aksak) meters, modal melodies, and richly ornamented, often heterophonic ensemble textures. Typical instruments include gaida (bagpipe), kaval and zurla/zurna (flutes/oboes), tapan (large double-headed drum), tambura (long-necked lute), violin, clarinet, and—especially in brass traditions—trumpet, tuba, and baritone horn. Vocal styles range from raw, open-throated village singing to refined urban romances such as sevdalinka. The melodic language often draws on Ottoman/Turkic maqam and Byzantine liturgical modalities (e.g., Hijaz/Phrygian-dominant flavors), with microtonal inflections and copious ornamentation. Dances like kolo, oro, horo, and čoček are central, and songs frequently address love, weddings, migration, and local heroism.

Polyphonic chant is a sacred vocal tradition in which two or more independent voices sing liturgical material at the same time, creating vertical harmony from originally monophonic chant. Emerging from the practice of adding a second voice to chant (organum), it favors perfect consonances (fourths, fifths, and octaves) and often places a sustained chant line (tenor) beneath more florid upper parts. In its classic medieval Western form, it is unaccompanied (a cappella), modal rather than tonal, and frequently governed by rhythmic modes. While the Notre Dame school in Paris codified much of its technique, related polyphonic chant practices also exist in other liturgical cultures (e.g., Georgian and Corsican traditions), each with distinctive sonorities and voice-leading norms.
