Fun Story: My director kept telling me and my tenor sax buddy to play softer. No matter what we did, it wasn’t soft enough for him. So getting frustrated, I told my buddy “Dont play this time. Just fake it”
Our Band Director then informed us we sounded perfect.
To my readers: “p” means quiet, “pp” means really quiet. I’ve never seen “pppp” before haha.
On the contrast, “f” means loud, and “ffff” probably means so loud you go unconscious.
