Music of Ireland
O'Donoghue notes the autobiographical "Memoirs" of John Carteret Pilkington and also draws on the miscellaneous collection "Essays, Poetical, Moral, &amp;c.", 1769, by Thomas Newburgh (c.1695–1779), attributing the relevant material to his father Brockhill Newburgh writing in 1743, and the early or contemporary sources in Thomas Campbell's "Philosophical Survey"; Conran's "National Music of Ireland"; the "Gentleman's Magazine" 1759; and his own reference work, "Poets of Ireland". Campbell in a notice in "A Philosophical Survey of the South of Ireland" (1776), in asserting Poekrich's eminence in music, stated that performances of his instrument, while lacking great force, produced the sweetest of tones.
