Yap's poetry is distinctive for an unusual linguistic playfulness and subtlety that is able to bridge the rhythms of Singlish with the precision of acrolectic English. Unsurprisingly, the craft of Yap's voice has the admiration of other writers. Anthony Burgess has written that he encountered Down the Line "with elation and occasional awe", while D. J. Enright has praised Yap's "sophisticated cosmopolitan intelligence". The Oxford Companion to 20th-Century Poetry describes Yap's poems as "original, but... demanding: elliptical, dense, dry, sometimes droll. At their best, they shuttle between playfulness and sobriety and are alert to the rhythms and contours of the natural and the peopled landscape, seasoning insight with compassion." His first collection of poems Only Lines was published in 1971, when he was 28. It had a first print run of 2,000 to 3,000 copies. Its whimsical, wordplay-based humour captured the hearts of poetry lovers, and it won the first poetry award from the National Book Development Council of Singapore in 1976. An analysis of the poems from Only Lines finds moments of both celebration and apology for the power of the written word. At times he begins his verses as if in mid-conversation with the reader: The pun on the word 'plot' in this passage, denoting both a storyline and a piece of land, suggests a dimensionality in the language that belies the dismissive adjective 'only'. Other signature features of Yap's poems include his choice of simple words, and the use of all-lowercase style favoured by American poet E. E. Cummings. Yap's second collection Commonplace was published in 1977. The third collection, Down The Line was acclaimed and won Yap his second Book Council Award. In 1983, Yap was honored with Singapore's Cultural Medallion for Literature and the South-East Asian Write Award in Bangkok. Yap described this as one of the high points in his literary career. Translations of his books were published in many Asian countries, mainly in the Japanese, Mandarin and Malay languages. In 1988, Yap won his third Book Council Award for Man Snake Apple & Other Poems. One of Yap's short stories was included in Singapore Short Stories, which was used worldwide for the 'O' Levels from 1991 to 1992. Yap's poems 'In Passing', about the restlessness of the modern world, and 'Old House at Ann Siang Hill' were included in The Calling of Kindred: Poems from the English-speaking World, a poetry anthology prescribed for the 'O' Levels in Singapore from 1996 to 1997. His poems also have been included in a literature course offered by McMaster University in Ontario, Canada, and collected in anthologies like New Voices of the Commonwealth, The Flowering Tree and The Second Tongue: An Anthology of Poetry from Malaysia and Singapore. Selected poems of his are on the reading lists of West Virginia University and New York University Sydney. Yap also served as the general editor of literary magazine Singa, first published in 1981. In 1998, Yap received the Montblanc-NUS Centre for the ArtsLiterary Award for English. A selection from each of Yap's previous books was compiled in The Space of City Trees: Selected Poems published in 2000. Extracts from The Space of City Trees were subsequently published in The Straits Times' Life! Books section. NUS Press published The collected poems of Arthur Yap and Noon at five o'clock, a collection of his short stories, in 2013 and 2014 respectively. Yap's paintings decorated both book covers. In 2015, Down the Line was selected by The Business Times as one of the Top 10 English Singapore books from 1965–2015, alongside titles by Goh Poh Seng and Daren Shiau.
Painting
Yap was also a painter. His passion for painting began in 1967 when he was working as a Pre-University English Literature teacher at the Serangoon Gardens English School. During the weekends he would pick up the brush, expressing himself through his abstract works of art. On 13 April 1969 Arthur Yap held his first solo art exhibition featuring 44 square abstract paintings at the National Library in Stamford Road. Yap went on to have a total of seven solo exhibitions in Singapore, as well as participating in group exhibitions in Malaysia, Thailand and Australia. Yap's paintings were also chosen to represent Singapore at the Adelaide Festival of Arts in 1972.
Death
After a two-and-half-year battle with throat cancer, Yap died in his sleep at home on 19 June 2006. He was 63. The cancer had recurred in 2004, and Yap underwent major surgery to remove his voice box.
