Éliane Radigue – OCCAM XI

by 5:4

For the second day of my Éliane Radigue long weekend, another work from the OCCAM OCEAN series, and a particularly austere one. Composed in 2013, OCCAM XI is not simply for solo tuba, but solo microtonal tuba, specifically that of British tubist Robin Hayward. Not that that’s immediately obvious from the music, but then it’s not immediately obvious that a tuba is involved at all.

The work’s 13-minute span falls into three sections, the first of which contains a low F, articulated as a series of fragile fragments, air and vocal noise at the fringes, with both its pitch centre and its overtones undulating slightly, moving between different vowel shapes. The sound is a curious cross between throat singing and a kind of ancient reed instrument—almost, in fact, as though the instrument itself had found sentience and was attempting to speak; decidedly fascinating and unsettling. The second section, around the midpoint, shifts up a fifth and becomes more sustained, the tuba’s sounds much less differentiated but suggesting something more ritualistic, its strangely dogged persistence hinting at some higher purpose, as though casting a muffled incantation. With barely a minute to go, the instrument shifts up to a high E, now permanently sustained, with its upper partials very pronounced, dancing all over its voice-like timbre. A sound like this emanating from a tuba is pretty remarkable, and it makes for a fittingly leftfield coda to a work that’s a surprisingly intense and magical experience.

This performance, by Robin Hayward, was given at last year’s Tectonics festival in Glasgow.
