Sometimes a composer is obliged to use this method on account of the very low register of the double bass, especially if a double bassoon is not included in his orchestral scheme.[14]

D. Combination of strings and brass.

Owing to the dissimilarity between the quality of string and brass tone, the combination of these two groups in unison can never yield such a perfect blend as that produced by the union of strings and wood-wind. When a brass and a stringed instrument progress in unison, each can be heard separately, but the instruments in each group which can be combined with the greatest amount of success are those whose respective registers correspond the most nearly; Violin + Trumpet; Viola + Horn;
