Cwm Rhondda is a popular hymn tune written by John Hughes (1873–1932) in 1907. The name is taken from the Welsh name for the Rhondda Valley. It is usually used in English as a setting for William Williams' text "Guide Me, O Thou Great Redeemer" (or, in some traditions, "Guide Me, O Thou Great Jehovah"), originally ("Lord, lead me through the wilderness") in Welsh. The tune and hymn are often called "Bread of Heaven" because of a repeated line in this English translation. In Welsh the tune is most commonly used as a setting for a hymn by Ann Griffiths, ("Lo, between the myrtles standing"), and it was as a setting of those words that the tune was first published in 1907. Tune John Hughes wrote the first version of the tune, which he called "Rhondda", for the Cymanfa Ganu (hymn festival) in Pontypridd in 1905, when the enthusiasm of the 1904–1905 Welsh Revival still remained. The present form was developed for the inauguration of the organ at Capel Rhondda, in Hopkinstown in the Rhondda Valley, in 1907. Hughes himself played the organ at this performance. The name was changed from "Rhondda" to "Cwm Rhondda" by Harry Evans, of Dowlais, to avoid confusion with another tune, by M. O. Jones. The hymn is usually pitched in A-flat major and has the 8.7.8.7.4.4.7.7 measure which is common in Welsh hymns. The third line repeats the first and the fourth line develops the second. The fifth line normally involves a repeat of the four-syllable text and the sixth reaches a climax on a dominant seventh chord (bar 12) – emphasised by a rising arpeggio in the alto and bass parts. The final line continues the musical development of the second and fourth (and generally carries a repeat of the text of the sixth). On account of these vigorous characteristics, the tune was resisted for some time in both Welsh and English collections but has long been firmly established.

The Welsh version shown above is a somewhat literal re-translation from the English version back into Welsh. Earlier versions of the hymn book published jointly by the Calvinist and Wesleyan Methodists had a version with five verses (i.e. omitting verse two of the six given in the
