I don’t know if I’m playing the noted right.

As I make a good sound I think I played it correctly but I just don’t know.

I’ve only played for like 3 days.

How do I tune it properly?

My response
You may not want to worry about tuning the saxophone too much if you have only played three days.

Focus more on good technique for your fingers, learning the notes, etc.

Tuning is important, but it will take some time to gain the control necessary to play in tune. Keep practicing every day and it will start to improve. And also be aware as you listen to yourself.

In general, people tend to be flat when they start playing. So your default position for the mouthpiece should probably be pushed in a bit.

I wrote this guide to tuning if you want to check it out,
