It is a widely prevailing impression, and one confirmed by the new instrumentation which Mozart and Mosel made for the Händel oratorios, that by their use of the organ these two masters (Bach and Händel) supplied those features of our instrumentation which were then lacking. Such an opinion is correct, if nothing more is meant than that in concert rooms where no organ is available, it must be replaced by other instruments.[170] It must not be inferred that this new instrumentation maintains reciprocal relations with the original accompaniment. In the former it is the string-quartet which serves as the foundation of the harmony, and it is only the wind-instruments which affect the color. With Händel (and Bach) the organ, which fills out the figured bass, serves as a background for all the other instruments; the color is added by all the other voices of the orchestra, whether strings or wind.
