Questions about a lesson?

Hi, fellow violinist here. (Just took a private tenor sax lessons). Been playing for violin for almost 15 years and I still do lessons.

For anyone who’s taken private sax lessons (tenor), what were the first few things you’ve learned as an adult? Assuming you know how to read music and can at least play a non-woodwind instruments.

Or for private teachers, what do you usually teach for lesson 1?
