For next lesson:

Continue to work on the exercises to improve your comfortability on the horn: lead pipe buzzing, lip slurs, & long tones. Refer to previous homework posts/ your notes if you have any questions with those. Try for 15/20 mins of these a day.

Major Scales: Great job learning those new scales. Continue to refine the ones you know.. try them in thirds for fun and always be aware of the note you are playing :) Next week, play the chromatic scale from C-> C, and from F#->F#

Duets: These are coming along nicely. I think as soon as you understand one really well, the others will come very quickly after. Try to be able to play along with one song for next lesson.
