Full description
Memorizing the notes on the guitar fretboard can be very tedious. That's why we developed this effective mini-course which helps you learn through fun musical drills rather than using dry memorization. This guitar learning app by String Systems is designed to help you master the fretboard through enjoyable and easy lessons and drills. Learn to navigate the guitar through this tried and tested method that has been developed by Prokopis Skordis over more than 20 years of teaching guitar privately and online. VIDEO LESSONS This mini-course includes 4 video lessons that help you practice effectively and apply your fretboard knowledge in a musical way. DRILLS - LEARN THE FRETBOARD IN 7 STEPS Practice through 7 levels of guided musical drills and fun backing tracks. FREE COURSES AND LESSONS Enjoy extra weekly lessons and explore courses like "SFS Fretboard Secrets", "Open Chord Workshop", and more. ABOUT STRING SYSTEMS My name is Prokopis Skordis. Here's a quick summary of my relationship with the wonderful art of music: I started taking classical guitar lessons at the age of 10, way back in the late 20th century (1987 - good times). I continued on to take theory, harmony, ear training, solfege, and other boring lessons, until I graduated from the Greek National Conservatory with a diploma in classical guitar. I was then fortunate enough to get a Fulbright Program scholarship which allowed me to enroll in Berklee College Of Music in 1997. I concentrated on electric guitar and also took classes in improvisation, composition, arranging, production, engineering, and more. I graduated "Summa Cum Laude" (which basically means "this guy is very good") in 2001, with a degree in Music Production and Engineering (although I now find teaching and playing way more fun). Since 2001 I have been living in Limassol, Cyprus, teaching music to students of all ages and levels, and taking part in various bands and projects playing guitar or electric bass. The last few years I have concentrated in developing new ways to teach (and learn) music more effectively. Since 2014 I have started the process of putting these methods into digital format. These are tried and tested effective methods, so expect more and more good stuff coming to this app! https://string.systems/privacy-policy https://string.systems/terms SUPPORT Need help?
