You can use the knowledge of how intervals work in tunes by seeing them in context using scales, chord intervals or both.

Hi edu_agca ... music is intervals! Everything you play, whether chords, melody, harmony ... everything you hear in any piece of music is the result of notes that are specific intervals apart ringing out. Intervals are just the 'distances' between notes, and it's the varying distances that create the music we know and love and recognize. So, what I'm trying to say is that you're already applying intervals every time you strum a chord or play a line.

Edu_agca - it might help if you check out Kirk's introductory lessons here: http://www.guitarforbeginners.com/chords.html
It explains it pretty well and will get you started.

There are a TON of songs that use a simple I-IV-V interval (the I, IV and IV chords of any given key). Once you read the lesson above, you'll understand better. It's not really as confusing as it seems!
