Hi Bob,

On page 21, the fretboard is missing the 4th interval, as well as the
note on the second instance of pattern 2 of 5.

The first pattern 4 of 5 arrow is not extended to include the fourth
interval. Looks like pattern 5 of 5 arrow should be extended to
include the seventh interval.

Also, the second paragraph under 4.2 intervals reads.

You will notice the position of the root note on the sixth string to
the root note on the third string.

Third should be fourth, correct?

Thanks,
Erik
