Music Theory I 24 lessons
Theory I covers all of fundamentals and the beginning of harmonic analysis. Learn the basic language of music and start to apply it to understand how composers write music and how musicians and theorists can begin to deconstruct it.

Lesson 1: Intro to Theory I
An overview of what you’ll learn in Theory I
45min.
Lesson 2: Basic Elements of Music
Learn the basic elements of music before we delve deeper into them: pitch (including melody and harmony), texture, meter, rhythm, form, timbre, and dynamics.
1hr. 10min.
Lesson 3: Intro to Meter
What is meter? How do composers create and organize the various overlapping background pulses of music?
2hrs. 27min.
Lesson 4: Intro to Rhythm
What is rhythm? How do we notate durations of sound and silence in music? We’ll also learn how to count in simple meter.
2hrs 1min.
Lesson 5: Meter & Rhythm - Part II
More in-depth coverage of meter and rhythm, including simple vs. compound meter, time signatures, and how to count in compound meter.
1hr. 35min.
Lesson 6: Meter & Rhythm - Part III
We’ll delve deeper into advanced topics in rhythm and meter, including triplets and other tuplets, polyrhythms, asymmetrical meter, and uncommon time signatures.
1hr. 35min.
Lesson 7: Dynamics & Articulations
We’ll learn how composers use abbreviations and symbols to indicate the degree of and alterations in loudness, along with notational tools to adjust the sound envelope.
1hr. 35min.
Lesson 8: Pitch (part 1)
We’ll now move into our next element of music: pitch. Here, we’ll learn what pitch is and how to name the white keys on the piano.
1hr. 35min.
Lesson 9: Pitch (part 2)
We’ll delve further into pitch, including learning how to notate pitch on the staff, different clefs, ledger lines, and tricks to read notes faster on the staff.
1hr. 35min.
Lesson 10: Pitch (part 3)
We’ll wrap up our intro to pitch by learning about accidentals, enharmonics, and the basics of the harmonic series.
1hr. 35min.
Lesson 11: Modes
We’ll learn about the historical ancestor to scales: the modes of the Medieval and Renaissance eras.
1hr. 35min.
Lesson 12: Scales I
We’ll learn how modes evolved into scales and how to construct major and chromatic scales.
1hr. 35min.
Lesson 13: Intervals I
We’ll learn about intervals, the distances between notes, and their two-part naming system. We’ll also learn how to quickly name common unisons, seconds, and thirds.
1hr. 35min.
Lesson 14: Scales II
We’ll learn about the three types of minor scales and the key difference between major and minor scales.
1hr. 35min.
Lesson 15: Key Signatures
We’ll learn what a key is, and how we can indicate major and minor keys using key signatures. We’ll learn how to quickly read and write key signatures for all of the major and minor keys, and how we can use these to quickly find our major and minor scales.
1hr. 35min.
Lesson 16: Intervals II
We’ll conclude our coverage of intervals, learning how to read and write all of the intervals and how to use intervallic inversion to make quicker work of it.
1hr. 35min.
Lesson 17: Intro to Chords
We’ve all heard of chords, but what exactly are they? We’ll also learn about the four basic types of triads and the basics of how to read fake books.
1hr. 35min.
Lesson 18: Chords & Scales on the Piano
Let’s take to our piano keyboards and learn how to quickly find and play the four types of triads, and patterns to help you quickly find and play major and harmonic minor scales.
1hr. 35min.
Lesson 19: Diatonic Triads & Intro to RNA
In our first foray into harmonic analysis, we’ll look at the diatonic triads in major and minor keys, and how we can make use of a powerful analytic tool called Roman Numeral Analysis (RNA).
1hr. 35min.
Lesson 20: Seventh Chords
Here, we’ll expand past simple triads into four-note chords. We’ll learn how to name them in both a classical system and in fake book.
1hr. 35min.
Lesson 21: Figured Bass
Much as modern musicians use fake book to indicate chords and allow for improvisation, musicians in the Baroque used a system called Figured Bass. We’ll learn the basics of that here and see how we use symbols from figured bass to show inversion in Roman Numeral Analysis.
1hr. 35min.
Lesson 22: Determining the Key & RNA
We’ll delve deeper into Roman Numeral Analysis, including tips for figuring out what key you’re in and how to indicate different things in your Roman Numeral Analysis.
1hr. 35min.
Lesson 23: Intro to SATB & Resolving Dominant (7th) Chords
In a preview of what’s to come in Theory II, we’ll take a first look at writing in a four-voice SATB (soprano, alto, tenor, bass) texture, and we’ll consider how to resolve V or V7 chords to tonic chords, or deceptively to the submediant chord.
1hr. 35min.
Lesson 24: Theory I Rapid Review
Here, we’ll recap what we’ve learned in Theory I.
