Lute Dulcimer
Instruments- discuss specific features, luthiers, instrument problems & questions
It may not be a dulcimer, but it isn't a lute either. A lute usually has 11 or more strings. I believe a Renaissance lute has 15 strings, and some courses are not fretted but only used for bass notes. The instrument in the video is more like a diatonic ukulele than a diatonic lute.
@ken-longfield is on the right track referring to it as what is often called a stick or walkabout dulcimer. The odd thing about Seagull's Merlin is that it has a 6+ fret but no 6 fret.
