Lecture notes relating to Welsh folk songs and folk tunes, including two series delivered at Bangor, 1934 and 1935, Coedpoeth, 1937, Llangefni, 1940, and a lecture entitled 'Neilltuolion Alawon Gwerin Cymru', undated but apparently delivered at Cardiff.
Notes, in journal form, mainly concerning his activities as a collector of Welsh folk songs. Numerous songs, together with provenance notes, are included.
Transcripts of tunes from printed and manuscript sources, mainly English but a few of Welsh provenance. The items, including some in the hand of Mary Davies and Jennie Williams, were apparently used for a comparative study.
Mainly psalm tunes, occasionally with words by Edmwnd Prys, and anthems. A saying in verse relating to the weather appears on the inside of the back cover.
