yes, Sheila, lots of good things you’re doing there.
your timing is very good, I think you’re even tapping your foot which is great (everyone should do that).
those few times when your intonation is off is in the higher register. This is common for beginner to intermediate level students.
the easiest range on our sax is the middle.
the lowest handful of notes are tougher to hit and hit in tune, similarly, the high end of the horn is easier to hit the notes but the intonation up there can be a bit painfully flat. this is because as we get higher we don’t compensate the air flow (support).
Those highest notes NEED more air to stay in tune to match the middle range.So as your notes get higher, and your air support remains the same you will get noticably flat due to not enough air. it’s as simple as that.
So, to get over this common saxophone hurdle, put more air into your sax as you get up to that high range.

Your A, B, and C were spot on at times and flat other times. Listen to yourself when holding the A for a bar or longer and see if you can hear it drop (getting flatter). That’s your sax telling you it’s not getting enough air!

It’s helpful to work with a tuner. I actually have one to put up on the site soon which I’ll announce but meanwhile you can find all sorts of tuners, apps etc.

Good for you to record yourself…it not only allows you to get constructive critizism but it’s listening back to ourselves that allows us to improve cause all these things I bring up we can’t always hear while performing…our mind is too busy with other things!

Great story Sheila thanks! that’s very awesome.
Have you gone thru the entire “How To Play The Saxophone – Complete Beginner’s guides” yet?
If so make sure part of your daily time is spent on the “Daily Practice Routine”
A solid hour on those exercises everyday will help a lot.
