Book 1 -- Lesson 9 -- Scales Part II.

This lesson will explain the fundamental relationships that exist between the letter names of each of the notes in the basic music alphabet. It will then show you how to locate any note on the guitar by using those fundamental relationships and the physical construction of the guitar. The second half of the lesson will show how to derive any major and natural minor scale. It will demonstrate the application of the general rules for each of the two scales, taking into account the intervals that exist naturally in the music alphabet. This lesson will give you the information you need to create any other scales, once you learn the defining rules for the scales you desire to build.

The Basic Music Alphabet

By convention, we use seven letters - A,B,C,D,E,F,G - to identify all of the discreet pitches in our musical alphabet. Note that continuous pitches, such as those created with a music synthesizer, will not be discussed here; that topic is beyond the scope of these lessons. In order to notate the entire range of pitches we require, each of the pitches represented by the seven letters are qualified by their placement on the musical staff, and, possibly, by the use of some number of "sharp", "flat", or "natural" (see lesson 6) modifiers. There is a fixed relationship between all of the letter pitches in the musical alphabet. Those relationships are independent of the scale, or even of the musical "key - or tonal center" that we chose to use. The relationship between letter names are based on the distance in half steps between each succeeding letter, and are ALWAYS as follows:

The Natural Music Alphabet - A,B,C,D,E,F,G

The distance in half steps between succeeding letter names in the natural music alphabet:

A to B -> two half steps

B to C -> one half step

C to D -> two half steps

D to E -> two half steps

E to F -> one half step

F to G -> two half steps

G to A -> Two half steps

COMMIT THESE RELATIONSHIPS TO MEMORY!!!

Notice that the transition between letter names varies between either one or two half steps. The distance between B and C, and the distance between E and F, are the ONLY letter names that have one half step. All other transitions require two half steps. Also note that there are a total of 12 half steps before we start again at the initial letter name. Let's clarify this by writing the twelve notes that take us from A to the next A:

A, (A# or Bb), B, C, (C# or Db), D, (D# or Eb), E, F, (F# or Gb), G, (G# or Ab), A

If you examine the twelve notes given above, you will see that five of the notes can have two names, depending on whether you label the note relative to the preceding, or proceeding letter. For completeness, you should know that it is possible to label any of the notes, even pure letter notes, with some number of sharps or flats. For example, the letter note "B", could, under certain circumstances, be labeled "A##", or A "double sharp." This is usually done when it is necessary to use altered forms of the same letter note in a single measure of music. We will ignore this notational technique for the time being because it is encountered infrequently in beginning and intermediate music. By the time you're playing advanced music, this will all be second nature to you.

Review lesson 6 if you don't remember some of the following terminology.

Written music is placed on either a line or a space on the staff, and the clef defines the actual letter name of each note's position on that staff. For example, the letter name of the note on the top line of the staff, using the "G" clef, is "F". A note in that same position on the staff using the "F" clef is "A". Once a reference letter name is defined by the clef, all subsequent letters and spaces on that staff are automatically defined relative to the reference letter. A letter name changes each time you move up or down from a line to a space or from a space to a line. That means that there are two letter transitions between adjacent lines or between adjacent spaces of the staff. If you refer to the first example in the paragraph, the letter name of the note one line below the "F" note on the top line of the staff would be two letters before "F" in the music alphabet: i.e., "D". The space immediately below the "F" would be one letter name before "F", i.e., "E". The important thing to remember here is that the staff always has a transition of one letter name as you move from a space, to a line, to the next space, to the next line, etc. The letter name of the note on the staff has no bearing on the number of half steps that exist naturally between subsequent letters of the musical alphabet.

Locating notes on the guitar.

Every musical instrument we use to play classical music has a well defined technique, or method, to produce each note in its own musical range. The guitar is fairly simple. It has "frets" on the neck of the guitar, and the musical distance between each fret is exactly one half step. Let's examine the guitar to discover how to locate any note. The thickest string is usually tuned to an "E". Let's assume for this discussion that we are using standard guitar tuning, and lets identify every note on the low "E" string. Refer to the natural music alphabet given above to see the number of half steps between letter transitions.
