Understanding the fretboard can be overwhelming. It is a web that is not easy to navigate. In this class we will use triads to view the neck and then apply this knowledge to make music - comping, soloing, and chord melodies. Join me in this weekly class to start unlocking the fretboard.

Arianna's class is amazing. Every class was extremely well thought out, always engaging, and had great cohesion of concepts throughout every class. It’s more reminiscent of a Music Conservatory Masterclass than your typical basic online class!

Frequently Asked Questions
Your guide to guitar theory
- Master basic chords and scales, focusing on clean fretting and picking.
- Study music theory fundamentals like intervals, key signatures, and chord progressions.
- Practice techniques such as alternate picking, legato, sweep picking, and tapping.
- Analyze songs to understand how theory and technique are applied in real music.

While self-paced online resources can be helpful, taking lessons with a skilled teacher provides structure, feedback, and motivation to progress efficiently. A teacher helps you focus on the most important skills and techniques, keeps you on track, and provides a dedicated practice time.
If you want personalized classes with a world-class guitarist, consider taking theory and technique lessons on Til. Til offers group classes over video chat with expert guitarists, allowing you to learn from the best teachers worldwide at half the cost of private lessons, all from the comfort of your home.
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.
