What you will learn about Music Theory for Beginners

The 7-day sprint
  1. Pitch on the Keyboard and on the Staff. Western music uses seven repeating letter names whose distances you can see on a keyboard, and the smallest of those distances is the half step.
  2. Beat, Meter, and Subdivision. Rhythm is organized by a steady pulse, grouped into measures by a time signature, and each pulse splits into either two or three equal parts.
  3. The Major Scale as a Pattern of Steps. A major scale is a fixed pattern of whole and half steps that you can start on any note, and that pattern, not the starting note, is what makes it sound major.
  4. Key Signatures and the Circle of Fifths. Instead of writing the same accidentals over and over, a key signature declares them once, and the keys line up in a predictable circle of fifths.
  5. Minor Scales and Their Three Forms. Minor scales share a half step between degrees 2 and 3, and they come in three forms: natural, harmonic, and melodic.
  6. Intervals, Counted Inclusively. An interval is the distance between two pitches, named by counting letter names inclusively from the lower note and then labeling the quality.
  7. Triads, Seventh Chords, and Chords From a Key. Stack notes a third apart to build triads and seventh chords, and the chords of a key are just triads built on each scale degree.
The 80/20: the 7 concepts that matter most
  • The Half Step Is the Ruler
  • The Major Scale Pattern and Scale Degrees
  • Beat, Meter, and Subdivision
  • Intervals Are Counted Inclusively
  • Triads Are Stacked Thirds
  • Key Signatures and the Circle of Fifths
  • Spelling Is Not Sound
The core idea, explained like you are 5

Music is built from the distances between pitches, and it is the pattern of distances, not which note you happen to start on, that makes a tune or a chord sound the way it does.
