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 viable tones because we have only 12 possible notes. Western music has produced such rules which describe how and when you can use these tones together. Although this is just convention, but by applying these rules you will instantly notice that something is wrong or unique instead of hearing the several common scales you hear commonly when you do not apply these rules. No special information is written in stone about the way these things are devised, but we are all so used to hearing music from an early age that contains these rules that we don't even consider about the options until we start to study musical theory in depth.
If you desire to play western style music and be a master guitarist, you are in need to understand these rules. A noteworthy part of these principles 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 utilise Half and Whole (W, H) to denote the gaps, and other manner is to list the number of semitones (1 or 2). Either way is taken, these three are same or all impart the gaps for the leading 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 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 letter in the rule - its a Tone once again, thus 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#
Thus, we have built 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 principle. For instance, 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 stands for the same thing). Some scales have more notes, for instance the chromatic scale has all 12 notes in it.
So in this way the scales work! The pattern depicts them and we pick whichever root note we want to create. The next step is to convert these notes into a formula so that we can play it.
