yeah in my circles we always called it the stronger than dirt jam, but it is not that either, this is really its own jam
here is the way we had it arranged,
before I get there, by the way, there is also an Ebmin in there which is subsituted for the G#min on the last time before it goes to the single note odd time "riffs".
Also there is a diminshed chord in there,in the midst of all this, I call it eb dim7, (I know, I know could be c dim7, or Gb or A!!!)
here is the fingering of where I start the diminshed and then I obviously will swing it down 3 frets up 3 frets, up 6 frets, up 9 frets. The normal dimisihed inversion like you would do on Let it grow or slipknot.
Here is the arrangement leading up to the 'riff"
note: this is how we arranged it, the Deads arrangement was loose and pretty musch different almost every night.
It does help to have a set number of bars arranged as to keep the band tight>
Riding along in emaj7
G#min 8 bars >>>>Emaj7 8 bars
G#min 8 bars>>>>Emaj7 8 bars
Ebmin 4 bars>>EbDim7 4 bars>>Emaj7 8 bars
Ebmin 4 bars >> To Riff **
Riff repeats 4 times and then Goes to the Dmin for 8 bars, after 8 bars of Dmin, the whole "Riff">Dimin sequence repeats (we did the "Riff" >>Dmin sequence 4 times and off the 4th Dminor instead of going back to the riff we would hit back to the Emaj7 ....Not exactly what the boys did, but effective
