thepianoplayer416 You should't rely on mneumonics like "Every Good Boy Does Fine" or "All Cow Eat Grass". Thinking about phrases would slow you down. Everybody can recognize the Middle C on the staff. Notes of the staff are arranged in order (line-space-line-space). Needs practice to instantly recognize notes. When notes appear to be in order going up or down you know it's a note run. All you need to read is the first note and you can play other notes after without thinking too much.
Mnemonics don't work. All they do it teach you to memorize the mnemonic. You sound smart but you still can't do much except be a parrot.
On the other hand, the "Landmark System" seems to be a workable method of learning the staff because we all sort of do it that way anyway as we learn. Basically, we all know where middle C is. All of us should also know where C is on the treble clef. Learn where C is on the bass clef. Then "landmark" G and A on the bass clef. With those positions locked in every other note can be located without too much slowing down. That goes away (supposedly) as you gain proficiency.
I still have to count ledger lines and write the note value on the sheet. There's no help for doing it any other way that I've found, but that's why you look over the score before playing in the first place.
