The next thing that you need to know is the fretboard, or the notes that
make up the guitar. The notes on a guitar go up chromatically. In other
words, they go up a half a step at a time. So if you were to start on A,
The notes would ascend like this... A, A#/Bb, B, C, C#/Db, D, D#/Eb, E,
F, F#/Gb, G, G#/Ab, A. Notice that, there is no sharp or flat between B
and C, or E and F. Sharps, flats, and half-steps will all be explained in
later lessons. Now study the fretboard and learn the notes. You might not
use them in the immediate future, but if you want to play well you will
need to know this.
The numbers 0 - 12 on the chart below represent the fret numbers.
