Lesson 1: Pitch & Octaves
In this first lesson we explore the foundations of pitch: how notes are named, how octaves work, and how registers organize the full range of musical sound.
You’ll learn where notes “live” on the keyboard and why the same note can appear in different octaves.
These basics will prepare you for every concept that follows in the course.
Lesson 2: The Clefs
In this lesson we explore how musical notation is organized on the staff.
You’ll learn how the five-line system works, how clefs assign pitch ranges, and how ledger lines extend the staff when needed.
These fundamentals allow you to accurately read and locate notes across the entire musical range.
Lesson 3: Major Scales
This lesson introduces the structure of all major scales using whole steps, half steps, and accidentals.
We examine the major-scale pattern and break it into tetrachords, making scale construction clear and systematic.
By the end, you’ll understand how to build any major scale from any starting note.
Lesson 4: Circle of Fifths
Here we apply the major-scale pattern to all twelve keys using perfect fifths and the circle of fifths.
You’ll see how keys are connected, why sharps and flats appear in predictable orders, and how to move through the full cycle.
This lesson forms the backbone of understanding Western tonal organization.
Lesson 5: Key Signatures
This lesson shows how key signatures summarize the accidentals of a scale and simplify musical notation.
We explore the order of sharps and flats, how each signature relates to the circle of fifths, and how to quickly identify any major key.
These tools make reading music cleaner and more intuitive.
Lesson 6: Scale Degrees
In this lesson we give each scale degree its proper name and functional role.
We connect stability, tension, and musical “gravity” to the overtone series, showing why certain notes feel resolved or unstable.
This understanding forms the basis of tonal movement and melodic direction.
Lesson 7: Perefct Intervals
This lesson explains how intervals are measured by number and categorized by quality.
We focus on perfect intervals—unison, fourth, fifth, and octave—exploring their structures, semitone counts, and characteristic sound.
These concepts prepare the ground for major, minor, augmented, and diminished qualities.
Lesson 8: Imperfect Intervals
Here we expand interval quality to major, minor, augmented, and diminished forms.
You’ll learn how semitone changes affect quality, how inversions transform intervals, and how compound intervals extend beyond the octave.
This lesson completes the interval system used throughout tonal music.
Lesson 9: Interval Inversion
This lesson shows how intervals invert, why numbers always pair to nine, and how interval qualities reverse.
We examine how perfect, major, minor, augmented, and diminished intervals behave when flipped.
Understanding inversions is essential for analyzing harmony and melodic structure.
Lesson 10: Minor Scales
In this lesson we study the three forms of minor scales, comparing how their altered degrees shape the sound and function.
You’ll learn the patterns of the natural, harmonic, and melodic minor, and how each deviates from the major scale.
This provides a starting framework for writing and understanding minor-key music.
