The north Wales tabwrdd existed 700 years ago. 'Tabwrdd' and the English 'tabor' both come from the French 'tambour', a word which goes back to the Persian 'tabîr'. 'Bwrdd' means a board or table, which describes the drum as something you could have a meal off. Plural - tabyrddau;  Drumstick- ffon dabwrdd, ffyn tabwrdd .

There is a Welsh traditional pipe called a Pibgorn. It has a single reed and is played with two hands.
It can be difficult to decide which 'pipe' is being referred to in the literature.

1884 Maesteg Literary and Debating Society meeting – talk by Mr T C Evans on Welsh Music, Central Glamorgan Gazette - Friday 25 January 1884

The 12th-century Giraldus Cambrensis noted that Welsh musicians played the harp and pipes.

1402 in the time of Henry IV: These laws were passed in response to the Welsh Rising of 1400, and imposed punitive sanctions on the Welsh. Against wasters3 minstrels etc. in Wales
Item, to eschew many diseases and mischiefs, which have happened before this time in the land of Wales…: it is ordained and stablished that no waster, rhymer, minstrel nor vagabond be in any wise sustained in the land of Wales
3wasters: Those with an idle and extravagant lifestyle.

The authorities had other reasons for watching over singers and itinerant musicians;... they feared the rounds made by those glee men with no other arms than their vielle or tabor, but sowing sometimes strange disquieting doctrines under colour of songs. These were more than liberal, and went at times so far as to recommend social or political revolt. The Commons in parliament denounced by name, at the beginning of the fifteenth century, the Welsh minstrels as fomentors of trouble and causes of rebellion. Their political songs encouraged the insurgents to resistance; and parliament, who bracketed them with ordinary vagabonds, knew well that in having them arrested on the roads, it was not simple cut-purses whom it sent to prison.

“Item: That no westours and rimers, minstrels or vagabonds, be maintained in Wales to make kymorthas or quyllages on the common people, who by their divinations, lies, and exhortations are partly cause of the insurrection and rebellion now in Wales."

quyllages = tax
kymorthas = tribute or exaction paid to the lord in several parts of Wales

A late sixteenth-century hierarchy of minstrels contrasted the four types of graduate minstrel (poet, harper, crowder, reciter) with four 'ofergerddorion' or inferior entertainers: the piper, the taborer, the fiddler (or player on the three-stringed crwth)...

1808 source a reprint of a 1794 book

This was confirmed in 1828:

Minstrels were prosecuted sporadically in Elizabethan Wales also, but it becomes increasingly difficult, especially after the 1572 Act, to distinguish entertainers from other wanderers who were regularly indicted as vagabonds. In 1556 a general order was made by the Marian Council against ‘players and pipers’ strolling through the kingdom spreading sedition and heresy. Multiple prosecutions of vagabonds, wanderers and suspect persons, including vagrant women, took place in Glamorgan in 1560, 1577
and 1586 but minstrels were not separately identified among them.

The pipe and tabor became ‘exceeding common’ in the seventeenth-century border counties where ‘many Beggars begd with it’ and ‘the Peasants danced to it’. Taborers and pipers were rarely found among the sixteenth-century Welsh minstrels but they seem to have become more numerous in the seventeenth century.

Poets and pipers were in competition: the music was increasingly preferred to the poets’ words. ‘By the saints of heaven’ – exploded Lewys Dwnn (c. 1550–1616) – ‘every Englishman [or anglophile] calls for a pipe rather than a poet of high repute’.
The instruments that the bards detested – fiddle, pipe and tabor – were louder than the single-harp and the crwth.

The poets wrote verse of an occasional nature, including satirising certain people in verses which might have the intensity of curses. An 'Englyn c.1613 Robert ap Huw Manuscript: 

"Fie dinning tabor, unenjoyable song,
Fie the knave who uses it;
Fie the pipe, not a sweet instrument,
Fie the fiddler's echo."

from 'Detholiad o Englynion' Bulletin of the Board of Celtic Studies, Part III, (1953), p.187.

[ Peniarth MS 146 .
Much of the collection was acquired and collected by the seventeenth-century antiquary Robert Vaughan (1592?-1666) of Hengwrt, Merionethshire.]

John Aubrey wrote: “…When I was a boy, before the late civill warres, the tabor and pipe were commonly used,
especially Sundays and Holydayes, and at Christnings and Feasts, in the Marches of Wales, Hereford, Glocestershire,
and in all Wales. Now it is almost lost: the drumme and trumpet have putte that peaceable musique to silence…”

In 1620 the grand jury made a presentment of the fiddlers, harpers, crowders, tabor-players and pipers who wandered up and down the country like rogues.  One minstrel was ordered to keep to his parish, but six musicians were sent to the house of correction. This was the last clearly identifiable campaign against minstrels in west Wales as a determined effort was made to rid Pembrokeshire of strolling musicians. (page 141)

“On 23 June 1653 William Lucas of Llansantffraid-ym-Mechain in Montgomeryshire was asked to play pipe-and-tabor
for a company of six morris dancers at Bwlchycibau, 3 miles away. While they were dancing outside an alehouse some
soldiers and countrymen came by and there was an affray in which three men (none of them dancers) were wounded.
Lucas did not know how it began or ended, ‘for he sayeth that he ranne away and hid himselfe in a bush a little from
the said house, untill a child brought him his pipe and tabor’.

In mid-seventeenth century Cardiganshire Griffith ap Evan of Caron was prosecuted for:
‘wandringe up & downe’ the county ‘w[i]th a taber, & pipe, roguinge & begginge’

There was a tabwrdd player living in Llandeilo in the 18th century.

In a satire on the fair, Siôn Mawddwy (fl. 1560–1613), an itinerant bard, described the alien music and dancing
at a shire-town where the Great Sessions were held. The town was crowded with people and entertainers but
the poet remained empty-handed there. In revenge he satirized the Englishness of the town, the undignified
minstrels, their excruciating music and absurd instruments: the rebec, lute, tabor, bandor and pipes.

The instruments that the bards detested – fiddle, pipe and drum or tabor – were louder than the single-harp
and the crwth and seem primarily to have been played to accompany dancing...Dancing became a dominant
form of recreation in late Tudor Wales, displacing other forms of entertainment. The poet’s livelihood was
threatened by the enthusiasm for private and public dancing. ‘This is not good’, complained Siôn Mawddwy,
observing dancers ‘shaking their tails’ at the fair.

Poem by John Dyer (1699 –1757), painter and Welsh poet

‘While on the grass
The mingled youth in gaudy circles sport,
We think the Golden Age again return’d,
And all the fabled Dryades in dance:
Leering they bound along, with laughing air,
To the shrill pipe, and deep remurm’ring-cords
Of th’ancient harp, or tabor’s hollow sound.’

There are only three dances that can really be described as Welsh morris; Y Gaseg Eira, and the processional and static versions of Cadi Ha.

Y Gaseg Eira (the snow horse, the Welsh name for a giant snowball) comes from Nantgarw in Glamorganshire, South Wales. This is a dance for eight men, and includes the unusual figure "pushing the snowball".  It is danced by Cardiff Morris, Isca Morris Men and Dawnswyr Nantgarw. Cardiff Morris have devised more dances in a similar style. There are also several dances for mixed couples from Nantgarw.

Cadi Ha (Cadi means Kate, Ha summer) comes from the Point of Ayr, in Flintshire and elsewhere in North Wales.  The processional dance is for eight men, with the additional characters Cadi and Bili.  Iit consists of crossing and recrossing. The static dance has more figures, in which the characters play an active part.  This dance is alive and well in Holywell, where there is Cadi Ha Festival every May Day. Isca Morris Men usually use the Cadi Ha processional as a coming on dance.

“…Whitsun-ale is solemnized with festivity of fiddle, and celebrated with caper after pipe and tabor…”
