Frequently Asked Questions

What is Guitar Interval Mastery?

Guitar Interval Mastery is a gamified course that teaches you all guitar intervals in 30 days or less. Through 150 bite-sized levels, you’ll learn intervals systematically, starting with key landmark intervals and gradually building to complete mastery. You’ll understand both interval shapes and semitone distances, transforming intervals from abstract theory into practical fretboard knowledge.

What exactly will I learn in this course?

You’ll learn to recognize and play all intervals on the guitar fretboard through a structured, gamified approach. You’ll learn the most common interval shapes first (covering 80% of real-world application), combined with their semitone distances so you actually understand how intervals work. Later levels teach rarer shapes for complete mastery.

Do I need any prior experience to start this course?

No music theory knowledge is required! The course starts with foundational intervals and builds systematically from there. As long as you can play your guitar and are comfortable with basic fretwork, you’re ready to start. If you’re familiar with music theory concepts, you’ll find the course helps make that theoretical knowledge more useful in everyday playing.

How long does it take to complete the course?

The course consists of about 150 levels. Most levels take 1-2 minutes to complete. If you complete 5 levels a day, you’ll finish the course in 30 days. If you complete 10 levels a day, you’ll have mastered intervals in just over two weeks! With only 5-10 minutes of daily practice, you can develop complete interval mastery.

How do I get access to this course?

This course is exclusively available to StringKick All Access members. When you join, you get instant access to Guitar Interval Mastery and all other courses on the site. You can start learning right away.

What if I don't like the membership?

Simple: if you decide the membership is not for you, you’ll get a full refund within 30 days. No matter the reason.

Why are intervals important to learn?

Intervals are the building blocks of all music. Chords are made of intervals. Scales are sequences of intervals. Melodies are intervals in motion. When you understand intervals, you understand how music is constructed. This makes everything else in music practical and applicable to your playing, rather than abstract concepts to memorize. Intervals unlock chord construction, scales, modes, arpeggios, chord progressions, and complete fretboard understanding.

Is this useful if I already know a few intervals?

Yes! Even if you already know some intervals, this course will systematically strengthen your understanding across the entire fretboard. The course lets you move quickly through material you’re already comfortable with while spending more time on areas that need reinforcement. You’ll develop complete fluency with all intervals, making your theoretical knowledge instantly practical.

Can I do this on my phone, tablet, or laptop?

Yes, the course works on any device with a web browser. You can login to StringKick on any device you own and switch between devices whenever you want. Whether you’re at home with your laptop or on the go with your phone, you can continue your progress whenever you have a few minutes free.
