Pretty thorough lesson, almost 9 mins. In the interval section I cover 3rds, 6ths, and 4th’s. I should also point out that when practicing it’s a good idea and strongly suggested to cover all the intervals. I also personally practice the clusters on all sets of three strings. I’ve posted a chart to accompany the lesson in the comments. Let me know if this helps anyone out. Enjoy!

**** For the basic scale shapes in the lesson when I get to number 5 it should be noted that number 6 is missing. The scale is there and its also in the chart. Just a flub in the video. 1st one of these I’ve done, so I can live with it, and it all works out.*****
