Bassett Jones (1809–1869) was a vital contributor to the prevalence of the triple harp in Wales during the nineteenth century Welsh cultural revival, despite being commonly overlooked by most historians. This thesis aims to analyse Bassett Jones’s role in the resurgence of the Welsh triple harp and triple harp making, as well as analyse the change in construction of the triple harp during the Welsh cultural revival. Since Bassett Jones’s involvement in this movement has previously been covered only peripherally, much of the information known about Bassett Jones is due to his affiliations with more well-documented individuals such as Lady Llanover and Carnhuanawc. This thesis focuses on the impact of Bassett Jones’s triple harps and the impact of Bassett Jones’s advancements on the construction of the triple harp. It takes into account the importance of his affiliations, as well as the advancements pushed forward by the invention and popularisation of the double-action pedal harp. It is revealed how Bassett Jones’s ingenuity created instruments to enable Welsh harpers to continue the enduring tradition of playing the triple harp. Bassett Jones dedicated his life to being a maker of quality triple harps and developing the common construction of the triple harp to be more durable. The changes that he devised resulted in more durable instruments, some of which continue to be used today.
