1971, Richard Korn, Orchestral accents, The dynamics of the celli have to be extended to the basses, for it would not make sense to have the basses operating under their last dynamics mark, of the previous bar, which is ppp.
1988, Elliott W. Galkin, A history of orchestral conducting: in theory and practice, The balance of strings in these two orchestras emphasized the lowest tessitura; Charles Burney criticized the Italians for having more double basses than celli and for playing the instrument "... so coarsely that it produced a sound no more musical than the stroke of a hammer."
