Hi.
After this semester at my school, I'm switching from Trumpet to Alto Sax. I've never played the sax and the reason I'm switching is that I wanna learn something new. Will I have trouble with embouchure and fingerings and is there anything I need to know?
Thanks.

You shouldn't have a problem. Obviously the embouchre is different. But the concept is similar. You want to only seal the lips around the mouthpiece just like you want to make your trumpet embouchre. Some of the fingerings will actually seem familiar.

Have fun with your new instrument of choice.
