In the Audio Chord Wizard video tutorials, the red lines appear in their examples as well.

Which brings me back to that opening section. Where would you start counting the first bar? Would it be when the guitar starts or when the rest of the band comes in on the cymbal crash? If the former, and you start counting the beats in the first bar, and the tempo is 111, I count 1 and 2 and 3 before I hit the next 111 tempo section. Does this mean the song is not in 4/4 time but 3/4?

Or should I be counting it 1 and 2 and 3 and 4 and?
