I just love arpeggios, as a matter of fact, I've been learning them. I can play all the ''boxes'' on the web page, but I like to take a deep look on everything that I learn, I did this with the minor pentatonic, blues scales, all the chords that I know, and of course, the arpeggios' shapes. What I always look for are the intervals or the notes.
What I noticed on those ''boxes'' for the dominant 7th arpeggios is that there are two wrong; the E and A arpeggios. I tried to play them in open positions, but the roots and some notes just don't agree with the interval structures of those arpeggios, at least for me. Can anybody check them out or help me to understand why's that?
Thanks in advance, have a happy new year! ^^
