"When I first tried out Prokopis' system, to my amazement I 'immediately' began to map out the scale sequences with SFS. Prokopis is certainly a talented musician and teacher."

"SFS is an absolute dream.  I have learned more from you in less than a year than I have in the last 20.  And I’m learning more and more every day. I can’t get enough of your material."

"The very visual approach of SFS has already unlocked my mind to the fretboard. Having bought many many books and videos etc, I can safely say this is the very best system for me."

Prokopis Skordis
Prokopis Skordis

I am a music geek fascinated with learning new things, and improving my guitar skills. But I'm also very passionate about helping others do the same!

After studying in the Greek National Conservatory, and Berklee College of Music, I began performing and teaching privately in 2001.

Since then, I have been developing new methods for effective musical training. My mission with String Systems is to share them with the world :-)

"…When I first watched a few of your videos, I instantly knew there was something different about this system. I cannot believe all guitar players are not taught this way. It’s so simple and it makes sense so quickly."

"I'm making actual melodies over each chord change (I play country so that's pretty standard). I can't explain how amazing this is. If I stopped here it would be worth its weight in gold."
