Yes, but my approach and most of the others don`t takes 7 or 8 years to master. Even beginners can do them if they practice.

The traditional way to tune with harmonics is to match 5th fret harmonic at 6th string to 7th fret harmonic on 5th string, then 5th fret harmonic on 5th string to 7th fret 4th string, then 5th fret harmonic on 4th string to 7th fret harmonic on 3rd string. The next one`s trickier and doesn`t really match in my opinion (or my tuner`s). You match 4th fret harmonic 3rd string with 5th fret harmonic 2nd string. Then finally, you match 5th fret harmonic 2nd string with 7th fret harmonic 1st string.

The problem with this approach (and the reason I came up with the one above) is that the notes are very high and hard to hear, especially in even the smallest amount of noise. Also, the 2nd-3rd string tuning doesn`t quite match in my opinion.

That is why I devised the method I outlined above and recommend it. Of course, if you have seven years to learn how to tune, you can do it Luke`s way.

I`m not saying your way is wrong. I tuned just using the 5th (and 4th) frets for years and years. Thats good enough for most purposes, and personally I never trust my own judgment (using any technique) if I`m going to perform solo, I always use an accurate electric tuner (or an accurate professional teacher :-D). I`ve never seen the point of using fancy tuning, the only reason I tune by ear is because it`s fast and you can keep your hand on the pegs while playing open strings - and I didn`t spent 7 years `mastering` it, it just came naturally when I became familiar with the intervals between the open strings. People who are a bit less incompetent that me usually pick it up alot quicker. Use your method by all means, or any method, as long as you can do it - tuning should never have to be a matter of skill or anything like that, just make it so it doesn`t hurt your head with little annoying out of tunenesses when you play.

I once used a method that started by using a tuning fork. After striking the tuning fork to make it ring I would place the handle end on the sound board of the guitar and when in tune one string would ring sympathically. I would lift the fork off the sound board and the string would be ringing if it was in tune. But now i forget the pitch of the fork and the harmonics involved. I wish I could remember this method for I would use it again.

When I use a tuning fork, it is A 440 -- the same note as the 5th string in standard tuning. I used a tuning fork for years before I bought an electric tuner. Forks are much more stable than the pitch I first learned with. They work great on acoustics, but not so well on electrics -- then you have to look around for a table or something wooden, though in desperation you can hold it to you ear and hum the note.
