Yes, it was. I'll add alittle something too. Although each string has a different range of harmonics, just with one string up to the 12th fret there are several. Take the D string with natural harmonics.
Fret.....Note....Range above open D
3.2...-..A.......(2 octaves and a 5th)
3.8...-..Gb......(2 octaves and a major 4th)
5.....-..D.......(2 octaves)
7.....-..A.......(1 octave and a 5th)
9.8...-..Gb......(2 octaves and a major 4th)
12....-..D.......(1 octave)
this pattern continues to the 24th fret.
As you can see where the harmonic is sounded on the strings, produces a different pitch. And each string being different, so will the harmonic pitches. So you can get any range of pitch just from using harmonics. I know this is a guitar site, but if you've ever heard Victor Wooten. He plays Amazing grace using only harmonics. Samething thing can be done with guitar.
Some may have only known the 5th, 7th, and 12th spots. But sometimes and I know Kirk Hammett from Metallica uses others. This is seen when you see a tab say [3.8], well thats what they mean. Same with A.H. which always has a pitch letter above it. I'll show you why if you didn't know.
Now these pitch letters are determined by where your thumb touches the string when you play a A.H.. I'll show a detailed pictures and the different pitches achieved from picking at a certain point on the string. I'll fret the 5th fret on the D string.
D:--5--~~>---[-V---]--X-----O-----U---[-----]----|
Key:
X = G (2 octaves and a 4th above open D)
O = B (2 octaves and a Major 6th above open D)
U = D (3 octaves above open D)
V = D (2 octaves above open D)
To most it actually might seem senseless, but if your soloing on those higher strings; it can be rather useful. Most hit artifical harmonics where O is located. Which is only the second highest. Try hitting it where the "U" mark is located to get that extra height. Same applies for the "V" marked A.H. which you can use to produce a harmonic that is alittle lower in high pitch strenght. Believe this or not, it will open up your playing by knowing these little things. Try it.
