"The String Partner Subscription is an incredible bargain! There is so much to learn. Since I've been subscribed to String Systems I've seen several other systems and none even comes close to yours. Really grateful I ran into you and your site!"

Ted Mardesich

"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."

Robert Pavich, Truckstop Hooligans

"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."

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 :-)


“Wow. I have been playing for many years, but never understood scales and modes until now. Thank you. SFS is the best! Can't wait to learn more.”

Robby Turner

“…Thank you so much. I love your lessons, keep it up! You have a calling for this work.”

Eric Bang

"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.”

Karl Sartin

“…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.”

Jimm Panik

“...I only wish the SFS method had been shown to me 50 years ago when I first tried to play a guitar…”

“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.”
