This article is about the musical instrument. For the Indian mobile phone service provider formerly known as CellOne, see BSNL Mobile.
A cellone is a large cello invented in 1882 by the German luthierAlfred Stelzner. It is held like a cello but tuned (high-to-low) to E3 A2 D2 G1, a fourth below the cello and two octaves below the violin. Its music is written in the bass clef. Its body length and its breadth slightly exceeds those of a normal cello, but it sounds much deeper than a normal cello.[1][2]
It is rarely used by composers. One of the few works where it is used is the Sextet in D major for violino piccolo, violin, viola, violotta, cello, and cellone, Op. 68, by Arnold Krug.[3]
