He published Y Cerub (anthems and hymn-tunes), Cydymaith y Cerddor , Y Delyn Gymreig , Caniadau Bethlehem , and Alawon y Bryniau (the publication of the last-named work had a somewhat remarkable effect — musical Wales was weaned from the music of the 18th cent. ballads and the way prepared for it to appreciate the songs composed by Joseph Parry , R. S. Hughes , and William Davies (qq.v.)); a volume of anthems, and a cantata (‘ Llys Arthur ’). With Edward Stephen ( Tanymarian , q.v.) he edited Llyfr Tonau ac Emynau , Jones being responsible for the greater part of the work of collecting, selecting, and harmonizing the hymn-tunes ; the two editors published a collection of chants also ( 1868 ).
