I know about All Cows Eat Grass / FACE / Every Good Boy Does Fine / Good Boys Do Fine Always
I find that I am saying those phrases in order to see what note it is. I know the actual keys by heart.
When I play music, it is pretty much muscle memory. I am not saying each note name in my head. In fact I just find see and know the other notes as “two up from c / 1 down from c”
What is the best way to really get to know the notes on the music sheet treble and base by heart?
