Diadic Park - part two
Now we've had a look at some of the 'basic' diads, we can have a look at what are termed 'open' diads. In the previous examples the intervals have all been within the bounds of an octave. If we now start to use compound intervals we can make sounds that have more depth and harmony. You'll see what I mean... =)
|----3------------|---------------------------12--|
|-----------0-----|---10----8----------8----------|
|-----------------|---------------------------9---|
|-----------------|-------------------------------|
|----3------------|---8-----5----------3------7---|
|-----------0-----|---------------------------0---|
Here we have the open form diads. Give them a go! You appreciate the difference an octave can make, especially on the guitar?
The above diads are:
- Two perfect 5ths (perfect 12ths), the latter with open strings
- A major 3rd (a major 10th)
- A perfect 4th (a perfect 11th)
- Two examples of octaves
If you have another guitarist in your band imagine what you could do! Pure sounding chords and complex harmonies. Say one guitar plays a D minor 3rd diad and the other plays an A minor 3rd - you've got a D7 chord that'll sound beautiful! But these diad ideas are great when there's only one guitarist, creating a kind of aural illusion that makes the listener (hopefully) think there's another guitar. A cheap little example of this looks something like this:
|----------------|------------------|---------------|
|---8--8/10--9---|---7---5-7-8-7-4--|---5--5-5/7--5-|
|----------------|------------------|---------------|
|----------------|------------------|---------------|
|---7------------|---5--------------|---3-----------|
|----------------|------------------|---------------|
|-----------------||
|---4---4h5--4----||
|-----------------||
|-----------------||
|---2-------------||
|-----------------||
And this .wav file is what it sounds like played on a 1/3 size, ten quid, out of tune acoustic at midnight on a pouring wet English night. I hope you get the idea anyway... =)
These type of triads lend themselves to loads of different technique, slides and legato hammers/pull-offs sound pretty cool. Sliding the whole diad (especially farther than four frets distance) can sound quite nice, even at high distortion. I hope you have fun playing around with this stuff and if you have any corrections/comments mail them to me...
Good luck!
