Ffeil NLW MS 24049A. - Instrumental tune book,

A secular tune book, undated, but watermarked 1828, and probably compiled during the second quarter of the nineteenth century. The tunes are largely unaccompanied by words, and some are marches, dance tunes and hornpipes, suggestive of instrumental use. Bass parts to some songs are included (e.g. pp. 136-140). Many of the tunes (which are indexed on pp. i-v) are of non-Welsh origin, such as Auld Lang Syne (pp. 1, 57, 78-79), The Hungarian March (p. 23), Duke of York's Cotillion (p. 24), Heart of Oak (p. 33), The Cuckoo (p. 35), Rule Britannia (pp. 36-37, 94), Downfall of Paris (p. 82) and The Huntsman Chorus (p. 90). The large number of Welsh tunes included suggest a Welsh origin, although non-traditional in background; where recorded, words are in English. Glan medd-dod mwyn is ascribed on p. 142 to 'J. Thomas [?Pentuwylo]'.
The Welsh tunes include Beaumaris Quick Step (p. 4), A Trip to Conway (p. 16), Llyweni Forest (pp. 17, 74), Nos Calan (p. 18), Morfa Rhyddlan (p. 18-19), Mentra Gwen (p. 19), Megan a Gollodd ei Gardas (pp. 20, 315), Meillionen or Sir Watkin's Delight (p. 21), Hufen y cwrw melyn (pp. 22, 26), Conceit Dafydd ap Gwilym (p. 28), Conceit William ap Owen Pencraig (Inco) (p. 29), Serch Hudol A Welsh Air (p. 31), The Men of Harlech's March (p. 65), Glan meddwdod mwyn (p. 67), The Break of Day (p. 68), Farewell Harp or Nos galan (pp. 69, 87), Gogerddan (p. 70), Penllyn Volunteers (p. 71), Ryfelgyrch gwyr Harlech (p. 72), Barmouth March (pp. 82-83), Llwyn onn (p. 84), The Rising of the Lark (pp. 97, 113), David y Gareg wen (p. 101), Merionethshire March (p. 108), Delight of the Men of Dyfi or Difyrwch gwyr Dyfi (p. 109), Black Sir Harry or Harri Ddy (p. 109), Cader Idris (p. 116), Pant corlan yr wyn (p. 123), Ffarwel Trwy'r Pwll by John Parry (p. 127), Pen Rhaw (p. 129), Noble Race was Shenkin (p. 144), Hunting the Hare (p. 145), Wrexham Hornpipe (p. 157), Dŵr Glân (p. 159), Mwynen Hafodelwy (p. 164), and Cader Idris alias Jeny Jones Llangollen (p. 166).
