Product Description

Okay, you have some chops, you know some licks but you find yourself getting lost unless you are playing in certain keys. Why? Want to be comfortable in every key? In this one hour video I show you my system for mastering harmonic devices such as scales and chords in all 12 keys. This is a time tested, proven method that I have used with my students for years and it works! It doesn’t matter what style you play. If you are constantly getting lost playing over changes and looking for a systematic approach for learning and memorizing scales and chords on the fretboard this video is for you. This system not only works for scales and chords but can be applied to arpeggios, interval training, and licks. You’ll also learn how to practice the harmonized scale or “chord scale” in all 12 keys. One of the chords that I show is a triadic 7th(no5) which was not shown in my Mastering Chords and Harmony video. This triad is used by Allan Holdsworth and I’m going to show you how to create a chord scale with it. Included with the video are transcription files in guitar tab and standard notation. These transcription files are in the PDF and Guitar Pro formats. Also included are neck diagrams, charts, and backing tracks to make learning easier and fun. You’ll also get to hear one of my newly unreleased guest solos at the end. If you are serious about becoming a better musician and guitarist let’s get started today!

    Have you ever wondered how jazz players seem to effortlessly improvise over chord changes, some of which involve wholesale changes in key? You could spend 20 or 30 years trying to develop a natural sense for this through trial and error. Or, you could cut to the chase with Derryl’s system for 12-key mastery. The system described in this DVD will have you playing scales over chord changes among all 12 keys in very short order. You will systematically begin to recognize key centers across the fretboard, until it becomes automatic. You will be able to change among all 12 keys from a single position, or move those scales anywhere on the neck within a specific key. The practice techniques described herein are highly effective, promote rapid progress, and will apply to any kind of scale you wish to learn. Derryl’s approach to 12-key mastery is logical, thorough, systematic, and will open up the fretboard in new and inspiring ways. Incredible bang for the buck! You can’t get this kind of training anywhere else for $35.
