Final answer:
The Baroque orchestra did not commonly include wind instruments and percussion instruments, focusing primarily on strings and keyboard instruments.
Step-by-step explanation:
In the Baroque orchestra, two things that were not commonly included were wind instruments and percussion instruments.
During the Baroque period, the focus of the orchestra was primarily on strings and keyboard instruments. Strings, such as violins, violas, cellos, and double basses, were the mainstay of the orchestra, providing melodic and harmonic support. Keyboard instruments like the harpsichord and organ were also prominent in Baroque music.
Wind instruments like flutes, oboes, clarinets, and brass instruments, as well as percussion instruments, were not as commonly included in the Baroque orchestra. It was not until later periods, like the Classical and Romantic periods, that wind instruments and percussion became more prominent in orchestral compositions.
