How is every one doing today?

Ok, so i've been checkin out the lessons again, and I came across the one i've been having trouble with. The diotonics. They were in with the eharmonics, which I kinda did understand. Could someone break this stuff down for me so I can start practicing more. That'd be just awesome.
wait...you came...for musical help...in the pit?

seriously, wtf?
We walked into the night

Am I to bid you farewell?

Why can't you see that I try
When every tear I shed

Is for you?
