Hello, I've heard that this song When I come around is very simpel and i found this great lesson and i wonder, how do i tune down the guitar 2 1/2 or what does he says at 0:24 http://www.youtube.com/watch?v=hIwj_twx5cI&mode=related&search=green%20day%20when%20i%20come%20around%20guitar%20lesson%20video
So anyway i got this KORG, okay tuner, nothing fancy or so, it works just fine. So there is like you can set if you use GUITAR/BASS and i use a Guitar, and after that the is somthing called FLAT witch brings up small b every time i click on "FLAT" and then sound but that dosent have anything to do with this. So anyway how do i do. I'm sorry but I'm not that good yet

dude, he says to tune it down a half step
two and half steps down is like lower than slipknot tunings

tuning down a half step means that instead of tuning the trings to EADGBE tune them to E flat A flat D flat and so on
He came, He played guitar, he kicked some ass Dimebag Darrell 1966 to 2004
If you mean tuning down a half step (and if it's the Green Day song When I Come Around, that is what you mean), push the flat button until there's one b sign on the screen, then tune normally.

I can't watch the video just now, so I'm just going by what you're saying.

If you cut down on these costs students won't learn so well, effecting the "quality"...
b = half step
bb = One step
bbb= one and a half step

Tune every string a half step down.

Standard guitar tuning is EADGBE. When "tuning down" it means that you will now tune to different notes. A "half step" down is like adding a lower note to your strings, but taking away a high note, so your tuning will now be Eb, G#, C#, F#, Bb, Eb. The "b" means flat, and the "#" means sharp. You should take a lookat a fretboard map, but I'll give you an E String example:

Standard E tuning:

0 1 2 3 4 5 6 7 8 9 10 11 12 = the frets (there are 12 notes 'til the "octave"

E F F# G G# A B C C# D Eb E

I believe the Green Day example you asked about is tuning to "Eb", so here that is

0,1,2,3,4,5,6,7,8,9,10,11,12 (again, the frets on the "E" string)

Eb, E, F, F#. G, G#, A, Bb, B, C, C#, D, Eb (the 12 notes on the E string in Eb tuning)
Theres a few lessons in the lessons section of the site that may be able to help you.
