Question: If I play a melody, let's say 2 bars in length, and I start the same melody on a second guitar as the first guitar enters bar 2, is that still considered to be a harmony? Or is this a different principle on it's own?
It is still a harmony, although it might not be as interesting as you'd like initially.
If you played exactly the same notes on guitar 2, you'd be playing "perfect unison" intervals (or pseudo-interval, according to some). One way of making this sound interesting is to play the notes on guitar 2 somewhere else on the neck, which changes the timbre of the note, though the pitch stays the same.
Alternatively, you could play the melody an octave higher or lower, on guitar 2.
In between all of that, you have all the other intervals, each of which have their own characteristics.
Maybe try playing unisons for 2 bars, then switch to octaves for 2 bars, then switch to say, fourths for 2 bars etc. Check out how it changes the character and fills out the sound.
Then, try mixing it up a little in those 2 bars: a few unisons, some octaves, something dissonant like seconds, something "sweet" like fourths etc.
PS: please correct me if I'm wrong anywhere guys. My theory is pretty basic.
