The <u>chromatic scale</u>, or 12 tone scale, is made by dividing the frequency range that is covered by an octave into 12 equal pieces (on a logarithmic scale). Each dividing point is a note on the scale. Since the octave note already occurs as the root note, we are left with 12 distinct note values (A, A{{sharp}}, B, C, C{{sharp}}, D, D{{sharp}}, E, F, F{{sharp}}, G, G{{sharp}}). '''Notice that there is no B{{sharp}} or E{{sharp}}'''. This has nothing to do with frequency - it is a convention in note naming. E - F spans the same frequency range as A - A{{sharp}}.

This matches the frets on the fretboard. The 12th fret is the same note as the open string, just an octave higher. Notice the 12th fret is exactly the middle of the string. All the frets between the nut and 12th fret are spaced such that each fret is 5.946% higher pitched than the previous fret.

== Scale Basics ==
A <u>scale</u> is a set of notes, ordered from lowest to highest pitch, typically spanning one octave. This provides a framework for melodies, as well as harmony. The most common scales are the 7-note major and minor scales, which is why we refer to note that is 2x the pitch of another note as the ''oct''ave - it is the 8th note in the sequence. Scales often imply <u>tonality</u> - melodies and harmonies seem attracted to a certain note in the scale (usually the first note), called the <u>tonic note</u>.
