and accurate finger placement. The lack of frets, as on the guitar fretboard, does allow greater variability in intonation though a bowed string instrumentalist, such as a violinist, "when unaccompanied, does not play consistently in either the tempered or the natural scale, but tends on the whole to conform with the Pythagorean scale" The open notes of the highest three strings may be played as stopped notes on the lowest three strings, offering advantages and disadvantages: Fingered tremolos, the rapid alternation of two notes, are best between two stopped notes on one string, in which case it is limited to the interval of an augmented fourth, or between stopped notes on two adjacent strings:Cecil Forsyth (1982). ''Orchestration'', p.356. .

Plucked strings
