I buzz in the mouthpiece when I get to work and when leaving from work to get to my place. That's about 30 minutes of buzzing all together
When I get home I do my warm up, long tones, slurs and scales. That's about an hour and a half
After that I spend some time from C in the staff to C above the staff doing long tones. Don't know how much time I spend there.
And finally, I usually spend some time jamming with my sister and her alto sax.
That's my daily routine, but occasionally I'll skip long tones from C to C. Some times I'll just warm up and jam. But I play everyday
