Although this article is geared towards guitar players, all the theory involved works on piano too, so please make the most of it if you play keyboards.

There are only two types of scale we're going to look at here, and in a guitar lesson it is only a 10-minute job to learn them. As I'm explaining it in print, it might take a few minutes longer, but it is easy, really! Let's start with a pentatonic scale. That's Greek for five notes and shows how long people have been tinkering with music.

!!!String 1 is the thinnest string, String 6 is the thickest. !!!

Tip: use just your first finger(left hand) for this

String 1: Play fret 3, then open string (no fingers!)

String 2 - same thing

String 3 - Fret 2, then open string

Strings 4,5 - same thing

String 6 - Fret 3, open string again

So the pattern,starting with first string is: 3, 0 3, 0 2, 0 2, 0 2, 0 3, 0. Hopefully you have just played an E minor pentatonic scale. Next, play it all backwards starting on the low 6th string. Have a friend play Em and G chords and jam along. Or play along with Heart Of Gold or Wish You Were Here.

IMPORTANT: We have just learned a scale pattern, but this is just a map of where you could go. You could (and should) start on different strings, try to sing what you're playing, and generally try to phrase things to sound musical. As soon as you can, abandon the up and down scale pattern.

Now let's look at Am pentatonic, probably the most widely used guitar scale. All we have to do is move the same pattern up the neck, though because there aren't any open strings it will not look exactly the same. In many ways this is the beauty of the guitar, because you can learn one pattern and easily transfer it to all the different keys. Again, starting with string 1 we get:

8,5 8,5 7,5 7,5 7,5 8,5 (now on string 6!)

You can use this over Am, Dm, Em and also over C, F, G - in other words, any chords in the key of C or Am.

Music theory is covered in my other hubs, so please check them out if this doesn't make sense, or use the comments box to get some more advice. Chromatic notes: when you are really conversant with the scale, try adding some extra notes for a more blues or jazz sound. For instance, instead of going fret7, 5 put in fret 6 too, but only as a fast and interconnecting note. This works ascending too - so you get 5,6,7 on three of the strings.

Let's look at major scales. First pattern is C major - starting on fret 3, string 5. Once you have this pattern, you can move it up the neck, or across one string, to play all the major scales.

Scales down the neck (not shown in the diagram)

This is a case of learn one, get 5 free! Find fret 12 - it's where the double dot marker is on most non-classical guitars. Now play the following pattern on string 1 : 12 11 9 7 5 4 2 0.

That's the E major scale. Again, it's good to do the whole scale backwards, or:

0 2 4 5 7 9 11 12

As the guitar is tuned EADGBE (low to high) you can simply play the same pattern on all the other strings to give you the scales of A, D, G, B as well.

The third string will give you a G major scale.The notes in a G major scale are:

G A B C D E F# G You can use this scale or the relative minor pentatonic, which is the Em pentatonic scale shown above, in the key of G.

Chords in G: G Am Bm C D Em F#m7b5. So a chord progression that uses G, Em,C, D for intance, will fit both these scales. Although both will work, the pentatonic is much easier to use.

Use these over blues chords, E7 A7 and B7 in the key of E Blues. For the A blues scale, I've added some essential but little-known info - mix the two scales together, and the major 3rd note works over A7 as it follows the chord notes more closely. When changing to the IV chord, go back to using the minor 3rd instead.

The E major scale is E F# G# A B C# D# E, and will fit the following chords:

E    F#m    G#m   A    B    C#m    D#m7b5

Notice the connection between the notes of the chords and the major scale.You could improvise or compose a melody line using this scale over these chords, in any order. 

Use the link below to look up scales on looknohands.com. It's a very useful reference for both guitar and piano. Use the comments box if you want any help with applications of the scales.There are links below to Fender guitars and Gibson guitars - both sites offer free lessons and demos of different styles, and are recommended.

When you have these scale patterns down, try to avoid improvising by just running up and down in a linear fashion. It's much better to have some intervals and jumps, and to use vibrato and pull-offs to breathe some life into the sound.

Youtube will serve you well, but there are also instructional DVDs to buy or rent.
