Can somebody transcribe the exercise played at 0:25 in this video?
I think it's major triads being played like this ( * after a number means it's up one octave)- 1 3* 1*, then the next triad is a tritone away.
Then when I looked closer, I thought maybe the triads starting on the 5th string are minor ( 1 b3* 1*). This would mean that you use the same fingering starting from the 5th and 6th strings.
