This is a piece of site-specific, quasi-spiritual, choral music.  The libretto chants the word "Bethlehem" repeatedly, whereas, the notes employed are derived from the easting and northing geographic Cartesian coordinates of the location; SA19 6YH = Easting:  268488,  Northing:  225235

Using these measurements as intervallic distances, the following tone row/cluster is produced;
Eastings:  (2) d, (6) f#, (8) g#, (4) e, (8) g#, (8) g#. Northings: (2) d, (2) e, (5) a, (2) b, (3) d, (5) g. Available notes/scale: d, e, f#, g, g#, a, b,

Bethlehem is a tiny village near my home in Carmarthenshire, which (of course) gains a large amount of media coverage during the Christmas period.
