HI. Here?s how I think TOOL?s Parabol is played. 
 
Tuning:(6th string to 1st)BEDGBE 
 
Now Adam said that he played Parabola With Dropped B, E tuning, and since parabol connects into  
Parabola, this means parabol is in that tuning also. 
Play this the entire song: 
Softly 
 
E|----------------------------| 
B|----------------------------| 
G|----------------------------| 
D|-0h2-----7h9-----0h2---7h9-7| 
E|-0-------0-------0-----0----| 
B|----------------------------| 
 
Happy? 
 
Then Connect into Parabola. 
 
Buh-bye
