The brac is the second smallest instrument in the tamburitza orchestre, playing second melody lines. The brac (or Brach or bas-prim) is often guitar-shaped, but could also be roundish like the bisernica. The body of the brac is made like a guitar, with the top half (or an area around the sound hole) in a different wood. The neck ends in a flat tuning head with a side ways scroll (like Fender). It usually has metal encased tuning machines (the metal plate is on the front, not on the back as with the Stauffer guitars). The 4 or 5 metal strings run over a loose wooden bridge to pins at the edge of the body, with some metal covering. Usually the first two strings are double.
The tuning is often an octave lower than the bisernica, E A d gg (the lowest 4 strings of a guitar). Playing the brac is with a plectrum.
