It seems like you're listing instruments typically found in a jazz big band. In the context of jazz big band instrumentation, the sections are usually categorized as follows:
- Brass Section: Trumpets and trombones
- Woodwinds Section: Saxophones (alto, tenor, baritone)
- Rhythm Section: Piano, guitar, bass, and drums
In a traditional jazz big band, strings like violins and cellos are not typically included as standard sections. Therefore, "strings" (violins, violas, cellos) is not a standard section in a jazz big band context.
