You should know the few fundamentals about the guitar, and the first step in is the understanding of notes that is the basis of music. The next step is to have knowledge about scales. The problem is that when some people are presented with musical scales for the first time, and they are being asked to play variations of these musical scales, it can become a disheartening undertaking. In this article we are going to search some of the causes for the existence of scales, and why we focus on them so greatly.
What are Musical Scales? A Technical View
We can construct music out of 12 possible notes because we have only 12 possible notes. Western music has evolved such rules which describe how and when you can use these notes together. Although this is merely convention, but by practicing these principles you will immediately find that something is improper or unique instead of hearing the various general musical scales you hear commonly when you do not apply these rules. No proper information is written in stone about the mode these things are devised, but we are all so used to hearing music from an early age that incorporates these principles that we don't even think about the alternatives until we start to study musical theory in depth.
If you desire to play western style music and be a great guitarist, you are in need to understand these rules. A fundamental part of these rules and conventions is the musical scales we use.
What is a scale? It is basically a sequence of tones, picked out from the 12 available, that work together to give an effect to the music. You can describe individual scales in a better way as a list of gaps between the notes. Half notes or Whole notes are denoted by the term Tone or Semitone which give the rule of using their basic letters, T and S.
Some people use Half and Whole (W, H) to denote the gaps, and another way is to list the number of semitones (1 or 2). Either mode is taken, these three are identical or all hand the gaps for the major musical scale:
1. T T S T T T S 2. W W H W W W H 3. 2 2 1 2 2 2 1
Let us see, how this works. Pick up a scale at random - G# major. This step states two things. First, our root note is G#. Second, we will be utilizing the Major scale formula to work out the notes.
So, we start up with our G# note, and add the first step of the formula which is a T, meaning a Tone. Thus, starting with G # and moving up a tone or two half notes puts us onto A#:
G# + T = A#
Next, we start with A#, and look at the next alphabetic character in the rule - its a Tone again, so we add 2 half notes to A#, to give us a C:
A# + T = C
Next, we start with a C and find out the formula - now it is a semitone, which takes us to C#:
C + S = C#
If we carry on with this we get the following:
C# + T = D# D# + T = F (remember nothing is like an E#) F + T = G G + S = G#
So, we have built up our scale of G# major according to our major scale pattern to get the notes:
G# A# C C# D# F G
Mostly, the scales we use have 7 notes in them but that is not an essential pattern. For example, the minor pentatonic scale only has 5 notes in it (its formula is 3 2 2 3 2 - I used numbers here instead of T and S because it has a few Tone and a half leaps, which is 3 half notes, and that is more easily written down as a 3 instead of something like "T + 1/2", but it all signifies the same thing). Some scales have more notes, for instance the chromatic musical scale has all 12 notes in it.
Thus in this way the scales work! The pattern describes them and we pick whichever root note we want to create. The next step is to change these notes into a pattern so that we can play it.
