Ho fiddle (Dan Gao)
Ho fiddle or Gao fiddle
is a bowed chordophone of Viet people. Ho fiddle is made from
sindora wood or rosewood. Resonator is made from a coconut shell or
hollow wooden tube of 4.5 cm diameter with one python- or
iguana-leather-covered surface. Being 82.5 cm long, body of neck is
round or square, and without frets. One end of the neck goes through
the resonator. The other end is known as a head of Ho, has
rectangular shape and is bent backwards. The very head is home to 2
tuning pegs. Bridge is made from bamboo or wood with length of 1.5
cm and is placed in the middle of the surface.
Gauge is made
from silk that pulls two strings towards the neck. This gauge serves
to adjust the pitches of sounds. Bow is made from bamboo or wood.
Bow's thread is inserted between the two strings, so that when Ho
fiddle is played, the bow's thread rubs strings and consequently
produces sounds. The two strings used to be made from silk, nowadays
are substituted with metal, and tuned at a perfect fifth namely Sol
- Re1, or Fa - Do1. Ho fiddle is often found
in Nh· Nhıc orchestra, orchestra of instruments of 8 timbres, stage
orchestras including Tuong, Cheo, and also plays an important role
in a Xam band.
