Limen, archaic Greek for ‘harbor’, describes the shelter of a shoreline indentation; the commerce of a seafaring marketplace; the liminal space, created or natural, in which we transit through ways of existing.   

Phone, greek for ‘voice’, or a human sound, recognizes that this sonification of oceanographic data-- the liminophone-- is a means to sonify ocean data, in real-time, to givevoice to the waters: the Singing Harbor.

The Wilderness of Ocean, ever-changing, ever-moving, unconquerable and unpredictable, is a great constant in human history.  Each time we put a toe in the surf,  we touch Odysseus’ sea, drops of Heraclitus’ river, Melville’s ocean.  

We encounter not just the nearest body of water, but the wild, the unknown, and the great certainty of change.  


Across the world and back to her native New York, violinist, vocalist, string arranger, writer and distance swimmer Rachel Golub defies categorisation, performing and recording with artists from Jay-Z and Florence + the Machine to Elliott Sharp, the Orchestra of St. Luke's, and Sting.

In January 2009, Rachel became the sixth person in history to cross the formidable Strait of Magellan-- a four-mile, two-hour distance in 39-degree water-- wearing a string bikini.

Solo projects include Go-Ray & Duke: The Yoga Sessions, with her yoga-music collective; and a 2011 solo violin album of Judaica, Songs from my Soul.  Recently she has also begun making short videos concerning the surreality of water.

The Liminophone is the marriage of Rachel's passions for music and urban swimming. The idea came to her after her first full winter of regular swims in a surreal, frigid winter ocean.  

Working together with longtime musical collaborator Nick Didkovsky, the two translated physiological and psychological experiences of swimming year-round into musical parameters: a soundscape to reflect the changing ocean.


Nick Didkovsky  is a guitarist, composer, and music software programmer. In 1983, he founded the rock band Doctor Nerve. In 1997, collaborating with computer music pioneer Phil Burk, Didkovsky created Java Music Specification Language (JMSL), a language for computer music composition written in the Java programming language (www.algomusic.com).  Nick has composed new music for Bang On A Can All-Stars, Meridian Arts Ensemble, Fred Frith Guitar Quartet, loadbang, ETHEL, ARTE Quartett, and others.  His Black Sabbath guitar lessons on YouTube are enjoyed by metal fans all over the world.
