Well, this has to be the most amazing lesson put together on the SI board, Can`s dedication to the SI board has been outstanding!
He`s done a great lesson on "Intervals, Intervals on Modes and chords" and you can check out this amazing lesson HERE (the text alone took him 5 hours of preperation!)
Also, this now qualifies Can for SI status and will recieve his badge very soon.
Congratulations mate!
