The selected works by the composers studied in this thesis might well stand as illustrative of the normal development of the use of the bass trombone near the close of the nineteenth century. Although notable progress was made by the cited composers in increasing the bass trombone's usefulness in the orchestra, each composer also continued to use the bass trombone as it had been used in previous years, such as in doubling bass parts, harmonic backgrounds, and for strong rhythmic punctuations.
