Hello
I was concerned about what scales go with chords and if you have to play every chord you see in a tune.
Thanks

You absolutely do not have to play every chord you see.  If there’s a ii V I progression, those chords are in the same key, so you could just think of one key for all three of those chords.

Being able to hear the changes in what you play for a solo is cool and shows you know the song, but playing too many notes shows you don’t understand how to use space.
