So I'm working on this custom, and the chord sounds wrong at this point in the tab (or maybe I'm crazy.)



As I understand it, the solid line on the spectrogram should go through the dark blurry line and it's way above it.

How can I use this info to fix the tab to play the right chord? Are the bars on the far left of the spectogram semitones or something like that?

It seems like this is something basic I should be able to grasp. Can someone explain please what I'm missing.

Think I figured it out.  All the lines line up now and it sounds right.
