In the ocean of literature on music theory it is hard to find a handbook which would be a simple, straightforward source with
immediate practical application.
During my studies in a music college, after having gone through the vast amount of instructional books, videos and CDs I
decided to develop a concise, practical guide book for my own use as well as for teaching purposes. This book proved to be
extremely useful and I would like to introduce it to you lesson by lesson.

INTERVAL
An interval is the distance between any two notes. On the guitar, the distance from one fret to the next, is a half step (half tone).

SCALE
To analyze scale structure, the scale formula is used, which shows the organization of steps of the new scale compared with the
major scale. (
+) indicates sharpened step, (-) a flattened step, (^) indicates half tone and (~) whole tone. Numeric symbols
(1,2,3, etc.) are the
degrees or steps of the scale.
A scale is a sequence of tones having specified interval relationship. Half-step movement up or down, which uses the
same
alphabet name twice in sequence, is a
chromatic scale:
C^C+^D^D+^E^F^F+^G^G+^A^A+^B^C

A diatonic scale is a series of whole and half steps which proceeds up or down. A diatonic scale has no chromatic tones and
uses
different alphabet letter names. MAJOR and MINOR scales are diatonic scales.
A MAJOR scale alweys has the following organization of whole-steps and half-steps:
C~D~E^F~G~A~B^C  or  1~2~3^4~5~6~7^8

The degrees of a MAJOR scale are also reffered to be the folloeing names:
1-TONIC, 2-SUPERTONIC, 3-MEDIANT, 4-SUB DOMINANT, 5-DOMINANT, 6-SUB MEDIANT,

The fundamental tone in diatonic scale called KAY-NOTE or TONIC.
