Udemy Guitar Intervals C Major, A Minor, and Related Modes [TUTORiAL]

In this course, we will explore the intervals within the Major scale and its related modes using a structured approach designed to enhance your understanding of interval relationships, mode construction, and fretboard navigation.

We will focus on the G-shaped C Major position (from the CAGED system), sometimes called position one as our reference. Starting with the C note on the 8th fret of the top string, we will systematically identify each interval within the C Major scale across all strings. This method involves locating the major 2nd, major 3rd, Perfect 4th, Perfect 5th, Major 6th, & major 7th intervals on each string before moving to a new root note, such as the D note located on the 5th fret of the second string. We will measure each interval related to the D Dorian mode, all the notes being the same but the tonic changing from C to D and there for the intervals changing to those of a Dorian Mode. We will then repeat this process for the next note, an E note, resulting in E Phrygian mode.

By repeating this process of shifting the tonic focus while using the same notes, we will:

• Develop a deeper familiarity with interval shapes across the fretboard.
• Strengthen our understanding of the modal relationships.
• Recognize intervallic differences between modes.
• Adapt to the B string tuning difference when mapping interval structures and shapes.

To aid visualization, we will utilize a custom Excel worksheet that simulates the fretboard. The low (heavy) string will be displayed on top, ensuring the diagram aligns with your playing perspective. Additionally, to maintain orientation consistency, instructional materials will be mirrored to match the player's viewpoint.

This structured approach will solidify your fretboard knowledge, making it easier to apply scales, intervals, and modes confidently in your playing. Whether you are new to intervals & modes or looking to deepen your understanding, this course provides a practical and methodical pathway to mastering the Major scale and its related modes on the guitar.

What you'll learn

• Identify and recall the C Major scale intervals (Major 2nd, Major 3rd, Perfect 4th, Perfect 5th, Major 6th, Major 7th) across all strings.
• Recognize the CAGED system's G-shaped C Major position and its role in scale navigation.
• Explain the relationship between the C Major scale and its modes, including how shifting the tonic alters the modal structure.
• Describe the impact of B-string tuning differences on interval shapes and positioning.
• Demonstrate the ability to locate and measure intervals on every string using C Major and its modal centers (D Dorian, E Phrygian, etc.).
• Use an Excel fretboard diagram to visualize and reinforce interval and mode relationships.
• Compare and contrast the intervallic differences between C Major, D Dorian, and E Phrygian to understand modal construction.
• Differentiate how intervals are mapped when shifting the tonic within the same note set.
• Assess personal understanding of modal relationships and identify weak points in interval recognition.
• Critique and adjust finger positioning strategies for efficient fretboard navigation.
• Develop personal practice routines using the Excel fretboard tool to reinforce understanding of modes and intervals.
