Have *you* had a good experience with something web-based that teaches reading musical notation?

In my early 50s, I want to learn to read sheet music.

I am in the process of finding a music teacher (if you know the challenge here, you know it). Until I get there, it occurred to me try out what's available.

I'm cringing because I suspect many of the people I know here don't remember *not* being able to read #music

I ask for boosts.
