Re: Legit Tenor Orchestration
It's totally related to the range and projection of the instrument. Altos sound best in their mid-upper range so they usually get scored with clarinets, trumpets, and high horns. Tenors sound better in their mid range so they get scored with low horn parts, low trumpet parts, and a whole heck of trombone/bassoon/bass clarinet/euphonium. It doesn't have anything to do with the era the piece was written, it's just a conscious deciscion made by the composer and or the editor/arranger (especially if it is a transcription of an orchestral work).
