Reading music has become second nature to me, but it wasn’t always. Here is how I learned how to read music.

Every Good Boy Does Fine
The first mnemonic to help remember which note is which on the treble clef is ‘Every Good Boy Does Fine.’ These are the lines in treble clef. E for Every, G for Good, B for Boy, D for Does, and F for Fine. E, G, B, D, and F. From there, you can figure out the ledger lines, which are any notes above or below the staff, with the exception of a D, which hovers below the staff without a ledger line.
FACE
The spaces on the treble clef all spell out the word face.
