The musical Alphabet
The notes placed on the staff lines and spaces are named with letters of the alphabet. Unlike the 26 letters English alphabet, the musical alphabet uses only 7 letters: A, B, C, D, E, F, and G. Once we reach the letter G, we begin the alphabet all over again. Here are the letter names of the notes on the treble and bass staff.
If you look carefully, you will notice that the pitches of the bass staff are just two letter names apart from those on the treble staff. For example, ‘G’ in the bass staff is two letter names from ‘E’ in the treble staff.
