Bass (Berde, Begeš), is the largest of Tambura instruments. It is the basis of any Tambura orchestra, because it provides the basic harmony and rhythm. The Body is similar to the double bass, and it is built from the same material as the other Tambura instruments. The Head is shaped like a snail(as on a violin).
The length of the instrument is 1910 - 1940 mm (but there are also larger and smaller types). The Body length is 1082 - 1157 mm. Greatest width of the body is 640-690 mm, and maximum height is 207-220 mm. It has four strings that are tuned to the tones A - E - H1 - Fis1. The thickness of the upper board (ie the soundboard) is 3 – 4 mm. The touch-tone scale is chromatic and includes tones from fis1 to h .
In orchestras ,one or more Bass (Berde, Begeš) are used, whose number is proportional to the size of the orchestra. Its shares in the score are written in the bass (F) key, and sound an octave lower in reality. ©tamburica.org©
