Cello - Čelo is the same shape as Bass-Prim(Brač), but much larger in size. The Head is shaped like a snail. The Body (corpus) is in the form of a guitar and is composed of a frame, upper and lower boards. The frame and the bottom board are usually made of maple, but they can alo be made of other wood (maple, pear, plum, cherry, mulberry, walnut). The upper board (ie the soundboard) is made mostly of: spruce or fir.The Neck (handle) is cone-shaped, built mostly from the same wood as the trunk, and set in to it. The top of the neck is notched, and over it a board , 2 - 3 mm thick, is glued, made of hard wood (usually ebony or walnut).
The total length of the instrument is 1055 - 1085 mm. Body length is 485-495 mm. Maximum width of the body is 360-380 mm, a maximum height of the hull 80 to 94 mm. The thickness of the upper board (ie the soundboard) is 2 - 3 mm. It has four strings that are tuned to tones: a - e - H – F#. The touch-tone scale is chromatic and includes tones from F# to h1.
Its shares in the score are written in the bass key, and sound as written.
In larger orchestras, a Standing Cello - Čelo (like a small bass) is used, wich the player keeps upright between his legs during play. It builds from the same material and in the same way as normal Cello - Čelo and it has the same string, as well as tuning.
For the Standing Cello - Čelo be stable in the standing position, on the underside of the hull frame, a"foot" is built, which can be extended or shortened (similar to a violin -cello). The "Foot" is made of wood or metal.
The total length of Standing Cello - Čelo is 1200 - 1300 mm. Hull length is 665-680 mm. Maximum width of the body is 4500 - 500 mm, a maximum height of the hull frame 90 to 105 mm. The Soundboard(glasnjaca) thickness is 2 - 3 mm.
The touch-tone scale is chromatic and the scope is the same as with a normal Cello - Čelo (F# - h1).
