In Beethoven's orchestration there is almost always room for an independent viola part.
Classical and modern chamber-music in the sonata style consists mainly of string-quartets for 2 violins, viola and violoncello; string-trios (rare, because very difficult to write sonorously); pianoforte-trios (pianoforte, violin and violoncello); pianoforte-quartets (pianoforte with string-trio); pianoforte-quintets (pianoforte with string-quartet); string-quintets (with 2 violas, very rarely with 2 violoncellos), and (in two important cases by Brahms) stringsextets.
For example, it has often been said that the extent to which their orchestral viola parts double the basses is due, partly to bad traditions of Italian opera, and partly to the fact that viola players were, more often than not, simply persons who had failed to play the violin.
Thus there was quite as much important solo music for the flute as for the violin; and almost more music for the viola da gamba than for the violoncello.
Magnificent examples are Mozart's trio for pianoforte, clarinet and viola, his quintet for pianoforte, oboe, clarinet, horn and bassoon (imitated by Beethoven), his quintet for clarinet and strings, Brahms's clarinet-quintet for the same combination, and his trio for pianoforte, violin and horn.

Methyl Salicylate, C,H 4 (OH) CO 2 CH 31 found in oil of wintergreen, in the oil of Viola tricolor and in the root of varieties of Polygala, is a pleasant-smelling liquid which boils at 222° C. On passing dry ammonia into the boiling ester, it gives salicylamide and dimethylamine.
The violets comprise a large botanical genus (Viola) - in which more than 200 species have been described - found principally in temperate or mountain regions of the northern hemisphere; they also occur in mountainous districts of South America and South and Tropical Africa, while a few are found in Australasia.
