One of the main functions of the harpist during this period was to accompany poets and dancers. The end of the 17th century saw the introduction of the triple harp from Italy, and it became very popular. It had three rows of strings with the outer two tuned to a diatonic scale and the inner row to chromatic notes. This harp was also played on the left shoulder.

In 1819, Sebastian Erard from Paris developed the pedal harp and gradually the triple harp became less popular, although some leading harpist continued to play both instruments; John Parry the blind harpist and John Thomas (Pencerdd Gwalia) being two of the most prominent.

Many of the Welsh harpists were engaged by the aristocracy during the 18th century - the household of Lady Llanofer being one of the most noted, but as these privileged positions gradually diminished, they had to turn to the inns and taverns to earn a living. It was as accompaniment for dancing and penillion singing that the harp was prominent in Wales, with a special place at the Eisteddfodau, of course.
