Music is a perfect blend of logical, rational processes and intuitive creative expression. The Universe (you and I verse, or song) is also a perfect harmony of oneness. Therefore, we can look to music in order to understand much about ourselves and the cosmos.

12-Tone and 7-Tone Scales
The 12-tone musical scale consists of — you guessed it — 12 tones, or notes, labeled alphabetically as:
This is called the “chromatic” scale — 12 equal-interval steps up the scale (called “half steps”). As you can see, there are seven letters (A B C D E F G) and five sharps and flats (i.e. A#/Bb). The seven letters comprise the 7-note “diatonic scale” we’re all familiar with as “do, re, mi, fa, sol, la, ti…do.” In the key of C, these are C D E F G A B…C (the ending C is the beginning of the next “octave” wherein the pattern repeats at double the pitch (frequency) of the previous scale). This 7-tone scale consists of a combination of whole steps (two-note intervals) and half steps (one-note intervals) along the 12-tone chromatic scale. This 7-tone pattern is the same in all twelve keys.
