Course Description
Absolutely Understand Guitar: Complete Music Theory, Ear Training and Technique Course by AUG is a free online course in Music and Singing for electric guitarists who want to truly understand what they play, not just memorize shapes. It connects music theory, ear training, rhythm, and practical fretboard technique into one clear learning path, making it easier to build confidence and musical independence.
You will develop a strong foundation in chords and harmony, learn how notes relate through intervals, and understand how scales and modes work in real music. The course also covers notation and rhythm so you can read and interpret musical ideas with greater accuracy, while ear-focused practice helps you recognize pitch patterns and make faster musical decisions on the instrument.
As you progress, you will explore diatonic harmony, minor-key music, pentatonic approaches, and blues-focused playing, then move into triads, chord voicings, progressions, and more advanced concepts like modulation and substitution. By tying each concept to the guitar neck and common playing situations, this course helps you turn theory into sound and technique into expression.
