TalkingBass.com, they are from Mark Smith’s “Simple Steps to Sight Reading” course. He provides .pdfs of all his lesson material, and I had them printed out because I like working from paper vs. screen. The Sight Reading course fills a 3” binder.Where did you get those pitch exercises?
The course is not “fun”, IMO, but if you can discipline yourself to do the drills, it really pays off. When I was working on his course previously I got so that I could run through a page of the natural notes (no sharps or flats), on all four strings, frets 1-5, treating the whole notes as quarter notes, at about 60 bpm without looking at the fretboard.
His course produces results, but it is a bit of a slog compared to Ed’s curriculum, which to me is a lot more enjoyable due to the play alongs for so many exercises.
