Frequently Asked Questions

Your guide to guitar theory

Guitar theory for beginners
Learning music theory will provide you with a deeper understanding of the language of music, so you can play and improvise with more expression. To develop a strong foundation in guitar theory as a beginner, follow this step-by-step plan:
  • Learn the notes on the fretboard and understand intervallic relationships.
  • Study basic chord construction (triads and seventh chords) and common progressions.
  • Understand scale theory, focusing on the major scale and its modes, as well as the pentatonic and blues scales.
  • Learn how chords and scales relate to one another and how to use them to create melodies and improvisations.
  • Study rhythm concepts, such as time signatures, note values, and syncopation.

While online resources can help, consider taking guitar theory lessons with an experienced teacher for personalized guidance and feedback. A teacher provides structure, helps you apply theoretical concepts to your playing, and keeps you motivated when facing challenges.


If you want to learn music theory from world-class guitarists, check out the online guitar lessons on Til. Til offers video lessons with expert teachers, so you can dive deep into guitar theory with the best instructors right in your own home. With the right guidance and dedicated practice, you'll build a solid theoretical foundation that will elevate your guitar playing to new heights!

How long does it take to learn guitar theory?

Learning the fundamentals of guitar theory and applying them to your playing typically takes around 80-120 hours. If you practice 2 hours per week, that's about 1 year or 5 - 7 months if you practice for 30 minutes daily. For most people, the hardest part of learning guitar theory is understanding how scales, chords, and progressions work together to create music. To effectively learn guitar theory, finding a great teacher is crucial. A knowledgeable instructor can break down complex concepts into digestible lessons, provide practical examples, and help you apply theory to your playing, which is far more efficient and effective than self-guided learning.
