Greetings and welcome to, the world's most complete training system for fret-board harmony, aural skills, and improvisation.

My name is Dan Cosley. I'm a guitarist and composer, and founder of the site. I've created WotG as a personal exploration of musicianship on the instrument, and also to help beginning, intermediate, advanced, and even professional guitarists, study the key elements of musicianship on the guitar with greater efficiency.

As you know, the Internet is just bursting with information, but what is lacking is a system, that helps us train and master the fundamental elements that are common to all musical genres; that's what I've created here.

The core of the site are the six Level I courses. These are courses on Scale & Interval Patterns, Triads, Pentatonics & Hexatonics, 7th Chord Arpeggios, 7th Chord Inversions, and finally, the course on Modes.

These six core courses interlock to form a unprecedentedly deep and comprehensive 36 day training cycle. This is probably the site's greatest strength. It allows you to review (in a very efficient way) all of the basic elements of musicianship on the guitar.

Please take a look at the site tour, which shows the content and features of the site in great detail.

Also, rest assured that this is a risk-free proposition. If you sign up for a subscription, and you find that it's not for you, let me know within a week, and I'll refund your subscription.

I look forward to engaging with you in the discussion forums as you progress along "the way", and happy practicing!
