This will endeavor to help with the basics of jazz modal theory and guitar improvisation theory in general. Learning the basics is not only for those who want to eventually improvise, but helps immensely with ear training and learning solo's or favourite songs. Metallica's "Nothing else matters" solo for example is entirely based on the E Aolian mode. Santana's "Black Magic Woman" is all D Aolian. Once you know what root chord your dealing with, and the associated mode, its easy to figure out solo's like this.

What gets tricky, however is using modes for jazz jamming where the mode may change frequently eg every few bars or every chord. By this stage you really need to be able to recall your modes, their positions and fingerings as you can imagine, rather quickly. For me (not being anywhere near that stage yet), its a thing that hurts brain quite easily. I imagine at some stage of proficiency, as with most things, you "forget" to consciously recall your theory and it just happens.

However, before we jump in and try to learn modes it is necessary to learn reasonably well your Major Diatonic scale. It is from this that all of your modes are derived. Know these scales and you can figure out any mode.

Below are the 5 scales of G major diatonic. Each scale, by definition should start and end on the root note, but other notes above or below this that are in the scale may be included.

Now to interpret the notation:
1. The numbers above the fret board represent the fret number.
2. The numbers in the circles represent the finger to be playing the note.
3. The circle that is blue represents the root note.
4. Start at the root note on the 6th or 5th string and play left to right, bottom to top. Hit the highest root note and come back down.

NB: when possible, start and end the scale on a  root note.

Why do it this way? There are many ways at notating things like this. This one is essentially trying to drum in a pattern which can be repeated anywhere on the board to produce any major scale you want. Obviously by starting scale one on the 10th fret and you have D Diatonic.  Being a visual and pattern based method, it's a little easier than learning all the notes on each string then memorising the actual notes for each scale. Bler. However, if you can remember "2, 4, 1, 2, 4, 1, 3, 4, 1, 3, 4, 2, 4, 1, 2" then you already know the first major diatonic scale for any key you like.


Modes and Corresponding Chord Scale Examples


http://www.soundpunk..._serialNumber=2



So what does this all translate to?

a) the root chord of the scale is chord I (the left most)
:angry: the rest of the chords in the scale read from the root note to the right
c) the mode associated with the chord is shown above the respective column
d) one could figure out the remainder of the chord scales by starting at a given root chord, then writing the rest in,       
    remembering to add in the appropriate sharps or flats for the given root chord.

How it all fits together:

The naming of the modes is related to their respective root notes or chords. If you are playing the G major scale over a song in the key of G major, you are essentially playing in Ionian mode. If you are jamming to a song in the key of Am7 using the G major scale you are still playing in Ionian mode. If however, you play the exact same notes as the G major scale but start and end the scale on "A", then you are playing in A Dorian mode. Easy?


So back to Metallica:


The chords under nothing else matters solo are: Em, D, C, Em, D, C, Em, D, C, G, B, Em. Repeat.

This song has a particularly minor ("sad") feel about it, with Em being the root chord. Lets figure out mode to play over the top of it. For starters we can see that there are 3 modes with a minor feel. Dorian, Phyrigian and Aolian. The Dorian and
Aolian are by far the most commonly used.  Now if we refer to our Mode chart, we can see that the mode that would best fit this song would be E Aolian. E Dorian would probably not fit as the C is raised ie there is a C# thoughout which would be discordant over the natural C in the song.

So if you recall that the E Aolian scale is identical as the G major scale (except with an E root note), then you can start to jam over the top of these chords using the E Aolian scale (or G major scale with E root notes) it'll sound schmick.

For comparison play E Dorian over the top (D major scale with E root note) and see that although most of it fits the C# will make things sound tad wrong.


Metallica with solo:

[mp3=200,20,0,center] [/mp3]


You will notice that this solo is not note for note. That's not the point of this exercise (though you could make it that if you wish). The point is that I played the E Aolian scale over the given chords and just jammed it out - and it fit. If you are saying..."hang on how the hell is this anything like jazz??" listen to this...


Metallica with solo (jazzy version):

[mp3=200,20,0,center] [/mp3]


Still the same basic chord progression but with jazzier versions of the chords (Em9, D7, Cmaj7, Gmaj7 and Bm7) and of course jazzier rhythm. As for the notes played over the top - identical to those above: E Aolian. Fun.


And onto Santana:

[mp3=200,20,0,center] [/mp3]


This song is a pretty basic minor progression. Dm, Am, Dm, Am, Gm, Dm, Am. The mode that best fits this is D Aolian or if we have a quick glance back at the mode chart, F major diatonic with D root notes.


Alright. So thats the basic stuff to get one started in improvisation in general. Learning and recalling these 5 scales in all positions is the key to learning to jam and improvisation.

A few tips:

Practice these scales until bored shitless. Practice them in all keys - not much instant gratification but in the long run you'll be better off.

Pick a favourite solo. Find or figure out the chords underlying it then using the above theory figure out which scale would best fit it. Jam these scales out and try to pick apart the solo note for note.

Record some favourite chord progressions onto computer or tape or whatever. Try and make it loop based so you can just jam to it using the scales. NB: watch Soundpunk for a jamming thread to be launched soon.

Find musicians who are better than you and jam with them. Sure fire way to improve.


Soon: how the above scales can be used to derive the ever popular blues pentatonic scale and variants

the one way to scare the shit out of a self trained muso.. start talking modes or at least the theories behind them!!... great post will have a dig properly later.

^^^Thanks guys. Vagrant - It's an interesting phenomenon, especially with younger and starting out muso's. I remember when I started to learn this stuff when I was 15 and all my mates were getting kudos from the birds cause their guitar teachers were essentially showing them solo's note for note, which they could reproduce after practice. I however, was much less cool, cause initially I couldn't play the popular stuff as my guitar teacher refused to teach by rote. Instead he insisted on teaching the above theory which I duly learnt and practiced over a few years. In the wash up I was able to improvise and teach myself (essentially) anything which I reckon has made me a better player in many ways (this isn't to say that people can't get good by just learning from ear or doing it the other way)

Yeah i didn't fit into said category either.

There is definately more merit in having a teacher make you do the hard yards rather than just learning solo's like you said... i know people who learned that way and wished they hadn't.

I essentially taught myself by writing my own music (which is what drew me to electronic music).. never really liked playing other peoples stuff - although I would oprobably learn more if I did. with modes I basically learnt the shapes played against a metronome til i got bloody quick (think I got up to 220bpm fingering up and down the bass) and I found that although I don't really bother with the theory it allowed me to look at shapes when improving/jamming and try things.. so i am really a trial and error kind of player.  The speed helped me get out of situations when i was playing out of key - a few quick random notes and you find the key..lol

See , I fit into this category ..  I grew up learning the songs I loved , and improvising my own ,  but have always lacked knowing certain scales and keys so iv always struggled coming up with good original works ..    This is the stuff I need , and id be real happy to learn more about this .

Keep em coming woot , this is gold ..

Wow! What an amazing tutorial! That's fantastic, and so informative - even from a non-guitarist's perspective - and makes me want to go back to applying it the keyboard/piano/synth. And kudos for presenting what is often considered a heavy topic in such a digestible manner. The audio clips are pure gold!

I too sadly started out from a player's background instead of theory (with 'keyboard lessons' teaching Whitney Houston's 'Greatest Love Of All' to John Farnham's 'You're The Voice' though to the disco version of the 'Star Wars Theme', instead of being 'drummed' in scales and modes on classical piano, which was a headache as a small - and sometimes still as a big - kid).

And so I took up drums... much easier. ;)

Again, WOW! Easily rivaling the best-of-the-best content on this site!  :cans:

^^^Awesome. Even in the week or so that I took going over this stuff myself (its been a while since I've actually thought so hard about it), my jamming with our band has taken a new direction.

As there seems to be a bit of interest in the above I will soon be starting the Soundpunk Thread of Jamming Awesomeness where I plan to post loops of different chord progressions (and have people contribute some of theirs) so that we can all jam along using the modal theory. I also want to show you guys some fantastic blues    variants using the minor modes (look up Robben Ford on youtube for examples).....

^ Careful you'll end up with a couple of dozen remixes on your hands if you post cool guitar riffs up round here!

Dunno if I could control myself...  :(

Nice work , thats exactly what we want ..  Im still trying to find time to sit and and work through your theory ..    I got drunk this weekend and it all went out the window .. meh ...   

Keep em coming ...  With the addition of some real musical instrument area's,  SoundPunk is catering for everyone ..

OOO! A guitar forum!

Ive being laying dormant for a few months, some of you may remember me.... just stoppin in to say hi!  Im recording a bit of guitar recently so I may need some advice with micing etc.

Anyway, good to see the site is still going strong!


EDIT - I know a thing or two on the ol guitar, so if you've any questions re; theory etc, just ask!

Some quick tips


  • Start out learning the pentatonic scales. You can sound good quickly just by knowing a pentatonic pattern or two, and where to apply it.
  • Learn arpeggios. Then learn how to flow arpeggios smoothly. For example, in a C to F7 chord progression, play the C major arpeggio. If you end the C major by playing E G C, start the F7 arpeggio with the note in F7 that's closest note to C: Eb
  • Learn and apply chord scale relationships. That means know what scales sound good over a particular chord.
  • Take the time to try improvising, no matter how little you think you know; do play something over chord changes: single notes, scale bits, arpeggios.

The experiences you have had centre around 'Root' and Diatonic scale and jamming with a harmonious feel and jazzy feel. When our band improvises, we tend to produce
noise; which is atonal.  However, when jamming in the same Key, we tend to experiment with different scales such as blues, Japanese Sen scale and diminished
scale so that we can have maximum effects.

Thank you very much for your input.  I played a bit and definitely your tips of returning to the root note is pretty helpful.  Grasping the root note of each
chord when improvising is important.  It takes practices.

I play more often Free Jazz.  And I mix lots of noise and synth soundscape into the free jazz/noise/experiment.  In this case, scale improv is fun and creating
the Soundscape and occationaly abrasive tune is also more than fun.

Here is our Exits improvisation.  It is atonal.
