The Mnemonic Method uses simple sayings to help you remember the order and names of notes.
Step 1: Intro
I had originally written this guide as an aid for my piano students, thus I have kept it short and simple. Enjoy!
I also have an instructable posted for reading notes in the treble clef
Step 2: Reading Notes in the Bass Clef
The Bass Clef is used to show notes that are generally played with the left hand. The notes on the bass clef are usually found on the middle to left side of the keyboard.
Step 3: Staff and Bass Clef
The bass clef is also placed on a staff made up of 5 lines and 4 spaces. However, the notes in the bass clef are read differently than the notes in the treble clef.
Step 4: Bass Clef Spaces
The notes on the spaces are 'ACEG'. Remember this using:
All Cows Eat Grass
Step 5: Bass Clef Lines
The notes on the lines are 'GBDFA'. Remember this using:
Grizzly Bears Don't Fly Airplanes!
Step 6: Leftovers
There are two leftover notes that are often used in beginner piano. These two notes are Middle C and B.
