"Hasalpi" from Sumatra will be often mistaken for a "Kecapi" or
"Kudyapi" boat lute. The latter is a family name for boat lutes, but
this special model belongs to its own category.
The two strings are tuned in a minor third, and only the upper string
is used for the melody while the lower is plucked as a bordun.
This instrument normally belongs to the "Batak" people living in the
Toba region of northern Sumatra. It is interesting that my model
was found within a village from "Dayak" people living within the middle
of nowhere. However it came there, it might show that even the "Dayak"
had a natural interest and understanding of this instrument, as boat
lutes like this are well known there.
