Fourths and Fifths vs. others?

I hear some talk about how you should use fourths and fifths because they promote an "open" sound. I can't seem to find this when I use them.
In other words, can somebody give me an example of stuff they've done with many fouths and fifths?
Much obliged

OK, when you construct a simple chord, it consists of a note, the note a third above it, and the note a fifth above it, right?
The thing is, that depending on genre, instrumentation and whatnot, playing complete chords such as this can take up too much sonic space. This is especially true when guitars are involved, as a full, six voice guitar chord has a span of two octaves.
Leaving out the third can free up some of this space. But for that matter, so can leaving out the fifth.

Depends what you mean by open really. I tend to think emotionally/tonally open rather than sonically open. 4ths and 5ths don't really impart any distinctive tonal flavour (compared to flattened 7ths which are 'jazzy', flattened 5ths which are 'scary', etc).

Ahh, Asus4, jumpers for goalposts, love will tear us apart, Ian Curtis swinging slowly in the wind. Marvellous.
Stay below 9 when it comes to chords; don't follow the path of jaath.

It's flattened, so it doesn't count if we're talking rawk.

Howdy. Actually, it's parallel fourths and fifths -- several in a row. Listen to some Black Sabbath ("Iron Man," et al.) or Gregorian chant for some truly fine examples. And a fourth is just an inverted fifth, of course.
Uh-oh, I feel a lecture coming on...
In Classical music (Renaissance, actually), this sound was considered old-fashioned and clumsy, and eventually became forbidden. So were covered fifths. And octaves. Except in certain outer/inner combinations. And fauxbourdon (parallel 6/4 chords). And horn parts. And this drives composition students f*cking nuts.
But basically, parallel fifths were forbidden. Way bad karma. Uncouth. Grody to the max, even.
Partly, this is because newer, more harmonious means of tempering thirds were developed. Medieval theorists tuned the third to -- ready for this? -- the fifth of the fifth of the fifth of the fifth is the third of the first: c-g-d-a-e, so c-e. Going by overtones, a fifth is the ratio of 3:2, so this is actually... err, not nice. The natural major third is actually a 4:3, somewhat flatter than our equal-tempered major third.
Furthermore, this sound really was literally old-fashioned. Medieval music (actually, Gregorian chant, which is is all we have left of pre-Renaissance European music) was simple: just one melody, doubled exactly at an octave or fifth. No voice independence at all! And not only was the "harmony" exactly parallel to the melody, but it was always at a simple interval clearly related to the fundamental. But hey, with the way those Medieval dickweeds tuned notes, octaves and fifths were literally the only harmonious intervals.
Then a few hundred years later some dudes discovered that parallel fifths sound pretty bitchin' on a distorted guitar. And a generation later, their prog-rocking metaphorical descendants rediscovered classical harmony.
Same cycle, same hair length, but better drugs and more sex.
("Dude, you hear the latest Mozart album? It's wicked sweeeeeet!")
Err, we now return you to your regularly-scheduled cultural misunderstandings and subsequent flames, irregularly punctuated by thoughtful reviews of technology, hosted here on kvr.

sure, I use lots of fourths and fifths in my music - as well as seconds, major and minor thirds, etc.
use the notes which feel right for you!

So, where should i begin to learn to compose on my keyboard? I mean, i've developed some skills but i feel a little lost.... if i should study classical theory or begin to practice more thirds and fifhts.... an example, at the moment i'm learning the IIm7 V7 IMaj7 I6 progression in all keys. Is this useful, to learn this in ALL KEYS ?
