Natural Fun Outside the Box
  On the bass, position is defined as a "four fret, six  string  area  that  may  be  moved  anywhere on  the  fretboard".  
  Bass  players  call  "position" a  "box".    The  following core four™ fretboard diagram  may  be  used  by  any  four,  five  or  six string bass.  Figure 1.
  Let’s begin by assigning "one left hand finger to each of the four frets" on each string.  If a sound is "in position" it is best to play it with the pre-
assigned  finger.  This  greatly  simplifies  fingering and  will  immediately  improve  your  technique (skill and ability).  Figure 2.
  Next, let’s place the seven natural 1st octave major scale tone numbers ( 1 2 3 4 5 6 7 ) "in position". 
Natural ( ♮  ) means: "not sharp ( ♯ ) or flat ( ♭ )".  Remember, we already know which left hand finger to use on any tone number because 
we have pre-assigned a finger to that string and fret location.  Figure 3.
  Now, here’s a simple question, which left hand finger plays tone 7?  The answer - finger three.  On a four or five string bass, when you place 
your  left  hand  2nd  finger  on  the letter  of  tone number 1 of string three, you create form 
 
(circle three-two).  However, this becomes form form 
 (circle four-two) on a six string bass!
Not  only  do  you  create  the form,  but  you also define the key. 
Key is "the letter of tone number  1" that  your 2nd  finger is  on.  For example, if your 2nd finger is on the letter G and it is tone 1, 
then you are in the "key of G".  If your 2nd finger is on the letter C and it is tone 1, then you’re in the "key of C".  The "letter of tone 1" is the key.  
Yes, it’s that simple.  
  Don’t confuse yourself by thinking "signature”, as in "key signature", because this is a totally different concept and needs a lesson of its own.
  Let’s continue by placing a few 2nd octave major scale natural tone numbers ( 8 9 10 11 ) "in position". Figure 4.
  
   Here’s another simple question, which left hand finger plays tone 9?  The answer - finger one.
 
   There are sounds (tones)vthat may be played "in  position" but are lower in pitch than tone 1.  These sounds are identified as "underlined tone numbers".  
For example, underlined tone number 7, is one fret lower than tone number 1, but is still "in position".  Figure 5.
 
  All of the natural tones "in position" are isotonic.  Iso means "one", and tonic means "sound".   Therefore, isotonic means: "one sound with one location",
 and each sound has its own unique tone number.  Uni also means "one".  Uni + iso = unison.  Unison means: "the same one sound with more than one location"!
  We can play all the natural tone numbers, including underlined tone number 7, "in position”.  However, there are underlined natural tone  numbers  that  are 
one fret "outside" the position of form 
 and 
. 
Outside the position is called "extended position".  
  Extended position is created by playing one fret "on each side" of the position.  And when these two additional frets "outside the position" are  added  to  the four 
frets of the "position", a "six fret extended position" is the result.  In other words, extended position is a "six fret, six string area that may be moved to any key
(tone 1 letter) on  the  fretboard".  Bass players call extended position, "outside the box".  Figure 6.
 
  Here are all the underlined natural tone numbers that are located "in  position" and "extended position".  Notice the "unison 4.  Figure 7.
  We’ll end this lesson by showing all the natural major scale tone numbers that are found in both "position" and "extended position".  Figure 8.
  Now, when all the natural tone numbers of the major scale are shown, we can see that the 1st octave of form 
on a four or five string bass, becomes the 2nd octave of form 
 
on a six string bass!  Isn’t it time to get your Bass 6 String Fretboard Flashcards.
  Next time we'll introduce sharp and flat "chromatic" tone numbers, but for now, have some natural fun "outside the box" in extended position - 
  no matter how many strings you play.
  
   I’ll be listening...
