some of the same ideas in her Trumpet Concerto of 1963. Despite the tradition of choral music in Wales, Williams' portfolio of compositions were largely orchestral or instrumental pieces. Ballads for Orchestra of 1968, written for the National Eisteddfod, held that year in her home town, has all the colour and swagger of a mediaeval court. Outstanding amongst her vocal works are her setting of the Latin hymn, Ave Maris Stella, for unaccompanied SATB (1973), and Six Poems by Gerard Manley Hopkins, for contralto and string sextet (1958). The cycle is book-ended by two of Hopkins' best-known poems, Pied Beauty and Windhover, her music perfectly matching the rhythmic subtlety of the texts. These are amongst her most beautiful pieces, the soft melodic and harmonic undulations in Ave Maris Stella (Hail, Star of the Sea) suggesting as so often in her music the swelling of the ever-present sea. Welsh-language settings include Saunders Lewis's carol Rhosyn Duw, for SATB, piano and viola (1955), which she later incorporated into her large-scale choral work, Missa Cambrensis (1971). Her last completed works (1975) were settings of Kipling and Beddoes for the unusual combination of SATB, harp and two horns. The last music she wrote is actually in her Second Symphony, originally composed in 1956, and substantially revised in 1975. Legacy BBC Radio 3 devoted their "Composer of the Week" segment to her during the second week of August 2006, the year of the centenary of her birth. This resulted in several new performances of long-unperformed works, including her Violin Concerto (1950) and her Sinfonia Concertante for piano and orchestra (1941). March 2016 saw both the premiere modern performances of her large-scale Missa Cambrensis for soloists, chorus and orchestra (1971) and of her symphonic suite Four Illustrations for the Legend of Rhiannon (1939–40). Recordings Only a handful of Williams' works have been recorded. Her Second Symphony, Penillion, Sea Sketches and Fantasia on Welsh Nursery Tunes have been included in two Lyrita compilations, and several choral works, including Ave Maris Stella, were recorded for a Chandos Records collection. Ballads for Orchestra was recorded by the BBC Symphony Orchestra under the direction of Baldur Brönnimann and was included in volume 15 issue number 3 of BBC Music Magazine. An album of Williams' chamber music played by the violinist Madeleine Mitchell and the London Chamber Ensemble was released 2019. Principal works Two Psalms for contralto, harp and strings (1927)
