Linea Nigra (2015) began as an orchestration of my piano piece Canon Chorale (2005). It is scored for string octet, in this case the same configuration as a double string quartet. Most of the structure and content of the earlier work are retained as a kind of continuo, to which newly devised material adds range and contrapuntal detail.
The general technique is a variation of first species counterpoint. A set of short melodies in each of the modes of C major are heard in two- to six-voice, note-on-note canons at the unison and octave, creating a sequence of block chords, or a chorale. The resulting harmonic progressions may have a cloud-like feel to them especially as melodic lengths and part density increase, and chord roots become ambiguous. Towards the end, faster melodic lines develop out of a recurring a triplet pattern.
The title of the piece reflects my own quest for my biological and cultural roots. Linea nigra (“black line”) thus references the vertical line that appears on a woman’s belly in some pregnancies, while it also suggests Black lineage and survival. It could also stand in the sense of a melodic line, printed or otherwise.
My great thanks go to Ashil Mistry, who suggested the instrumentation and generously edited the score, as well as directing the performance heard here.
