What are scales for?

To put it this way, most of the music we're doing are tonal music. The main thing about tonal music is, of course, tonality. Every tonal song will have its own tonality or a key centre, so that's where the scales come in.

The scales consists of notes that revolves around the key centre of a song. For example, if the key centre of a song is in C, you will have a scale that might be CDEFGAB, depending on the nature of the scale[think of major, minor, pentatonic, jazz, blues, diminished, etc]. CDEFGAB is the C major scale and it's probably one of the most common used around.

Every note in the scale will relate to the keynote in a different way, but they are vital for tonal harmony. To understand that, you might want to play around with the scales and see how chords structure themselves in a scale.

Yes, scales can be, crudely, added to create a different tone. But that's where modulation and tonicization come in. Learn your scales before these fanciful terms come in. :D

Hope it helps.
 
^Above post.

Too profound, can you make it simple?

I can play C Major scale, but I don't understand what is the chord structure or key center.

Sorry!!! Am too stupid T.T
 
The key centre of C Major is C. To put it simply, C Major only consists of the notes CDEFGAB, so any other notes outside the scale, like maybe F#, might sound wrong.

Basic chords are structured using the scales and let me just use C Major scale for example.

C E G - major chord/C being the tonic note
D F A - minor chord/D being the supertonic note
E G B - minor chord/E being the mediant note
F A C - major chord/F being the sub-dominant note
G B D - major chord/G being the dominant note
A C E - minor chord/A being the sub-mediant note
B D F - diminished chord/B being the leading note

As you can see, all the basic chords in a C Major scale only uses the notes from C Major scale. But, of course, that's not always the case. For example, you might find a Gmaj7 chord[G B D F#] in a song which is primarily in C Major.

However, the above illustration only works for major scales and the same rule works for ALL major scales.

Sorry..... @_@ Sigh, I am stupid
 
Aye, bro, any music theory book will teach that too. You aren't stupid. :D

You need to learn scales because scales teach you basic harmony and basic chord structuring. Scales are vital in our music because a song has to be in a scale in order to carry a tune. It's that simple.
 
Like a friend of mine always sayz, theory is all well and good, but it's just theory.

Dude, you just need to:
1) practise to get and idea of what to do with scalez (books help!)
2) hear what others (sometimes not necessarily guitarists) do with THEIR scales
3) play what you want with the scales that sounds good:)

Ultimately, you need to HEAR stuff others play, and HEAR yourself.

You'll understand the theory more easily this way.
 
Scales: a particular sequence of notes which sounds good when played together. When a note not belonging to the scale is played, it generally does not sound good. Usually, a song is written in a single key/scale.

Different kind of scales gives different sound/mood, such as major, minor, melodic minor, etc.
 
Hmmmm, scales are a supposed to be a Combination of notes where you can run around and not sound wrong. Simply said its a guideline. Lets take for example the blues rock scale, obviously it creates a blues rock sound when played. Differrent scales are for different purposes, its hard to explain. It took a while for me to understand it too. But when i got the gist of it, it was really useful. Don't worry, when you continue playing you'll realise how to use scales to improvise. :). The best way is to search around on the internet for tips on what scales are for or of course, find a teacher. All the best!:)
 
hey man! as most of them mentioned above, you use a scale to sound nice to other people. I'm sure sometimes when you hear certain pieces of music (lets use Jazz Fusion, allan holdsworth) you feel like the person is anyhow playing cause the person is most probably playing out of scale.

in this case, i feel that you need to understand what a scale is perhaps. I usually explain it to people as your Do Re Me Fa So La Ti Do, something which most of all learn young. That is a scale and the most common one at it too.

So sometimes we hear people talking about about playing in different Keys and all that, well think about it, go listen to any of your songs and go sing that Do Re Me Fa So La Ti Do over it, it'll most probably sound different over a few songs. We have different Keys cause everybody has different voices and hence we need to adapt to them by playing in their keys (but i think if I talk about this I'll go out of context)

so back to the point. a scale is something you use when you want to sound like you are playing properly and to give people an impression that you know what you are doing as well. Some people can/may use other notes he/she adds on in a scale to create a certain kind of feeling BUT that's not important now man. what's impt now is your Do Re Me Fa So La Ti Do and as the guy above me mentioned, we have more scales that fit into certain genres but that's another story I guess.

about the combination of scales, there are many ways to understand it. Another way to think about it perhaps is that instead of seeing Do Re Me Fa So La Ti Do, you sing Re Me Fa So La Ti Do Re, you'll get a different sound but it's essentially the same only that it started on Re. and in theory it'll be called the Dorian Mode. BUT if you rearrange it it'll sound like Do Re Me Fa So La Ti Do. Of course this is just one way, there are many other ways man too so keep that in mind yeah :D

I hope you understand man :D anyway do correct me on anything if i'm wrong and if i've offended anyone, sorry!

scales are the basic to every music piece.

the grand daddy of scales for rock and roll is Pentatonic Minor.

Major and minor are the Do Re Mi.

Scales also help with finger stretching.

No Scales means no music.
No Scales means i dunno what are you playing.
 
i play quite a bit of scales but am not exactly sure what they're for. although they do help with getting familiar with all the notes on every fret.
