Crafting Harmony: Bernth's Journey with the 109-String Acoustic Harp Guitar

Bernth crafts his own acoustic harp guitar boasting an impressive 109 strings, a labor of love assembled from the bodies and strings of various plucked instruments, reminiscent of a ukulele. Constructing this marvel within the confines of his home, Bernth confesses to the considerable effort required to consolidate these myriad elements onto a single guitar body. Furthermore, he dedicates ample time to mastering the arrangement of chords and their resulting sounds.

The result is both haunting and ethereal. Every string produces a distinct tonal layer, weaving together into rich, multidimensional harmonies. In his YouTube video, Bernth performs an original composition titled “I Still Miss You”, showcasing the instrument’s full expressive range. The piece captures a bittersweet blend of experimentation and emotion — a sonic sculpture that feels alive.

A Study in Craft and Precision

Bernth reveals that tuning all 109 strings takes nearly an entire day. Each string is calibrated to a unique pitch, allowing him to create complex rhythms and melodic lines simultaneously — one hand for rhythm, the other for soaring solos. His delicate plucking technique mirrors that of a harpist, reimagined through the tactile immediacy of the guitar.

The instrument’s sheer size requires thoughtful posture and support adjustments, yet it remains a functional work of art — an embodiment of creative persistence and craftsmanship. Though the musician has not yet disclosed the full construction process, glimpses from his video reveal a remarkable blend of ingenuity and care.

Through this instrument, Bernth has redefined the limits of what’s possible with sound — proving that innovation often begins where curiosity meets obsession.
