Music Theory Classroom is a four-course, one- to two-year music theory curriculum designed for high-school and homeschool students. It covers the material studied by music majors in the first one to two years of college, but it is structured so that a diligent student can complete it in three 14-week terms.

The four courses in the curriculum include: two Fundamentals courses which are intended to be taken concurrently, followed by Diatonic Harmony and then Chromatic Harmony. Each course has 28 lessons, so the recommended pace is approximately two lessons per week.

This lesson introduces the entire Music Theory Classroom curriculum and ends with a bridge to the first lesson of both Fundamentals courses.

If you did not take the Fundamentals of Melody and Harmony course, you may need to do this lesson to prepare for the present course.

In order to move into the analysis we will do throughout this course, we need to learn how chords fit into keys.

Today we define a few terms that we will use throughout this course, and we look at how musical scores are set up so that we can read (and write) them accurately.

The assignment for this lesson will be reviewed at the beginning of next lesson.

Repertoire needed for this lesson:

Beethoven: Symphony No. 1

Beethoven: Minuet, WoO 82

Haydn: String Quartet, Hob. III:62

Hymn Tune HYFRYDOL

Functional tonal harmony arose historically from particular uses of counterpoint. The study of counterpoint is (at least) a whole course in itself, but this introduction to it will help us embark on our study of harmony.

The assignment for this lesson will be reviewed at the beginning of next lesson.

We begin the rules of voice leading by learning how to voice a single chord.

Repertoire needed for this lesson:

Bach chorale: BWV 96/6

Hymn Tune HYFRYDOL

Hymn Tune AZMON

Today we begin learning how to voice lead from one chord to the next.

The dominant seventh chord usually resolves by ascending 4th root motion, so we can follow the rules from last lesson, but the seventh of the chord requires special treatment.

When the root moves by 3rd or 6th, the voice leading is easy.

Root movement by second presents a special voice-leading problem.

We've learned how to go from one chord to another. Let's step back and look at the slightly bigger picture.

The assignment for this lesson will be reviewed at the beginning of next lesson.

Repertoire needed for this lesson:

Bach chorale: BWV 17/7

Bach chorale: BWV 292

Bach chorale: BWV 386

Handel: "The Trumpet Shall Sound"

Mozart: Ave Verum Corpus

Mozart: Eine Kleine Nachtmusik

Mozart: Sonata, K. 311

Sibelius: Finlandia

C. Schumann: "Sie Liebten Sich Beide"

Hymn Tune AZMON

The first inverted chord we look at is a chord with a very special function.

Repertoire needed for this lesson:

Bach chorale: BWV 17/7

Bach chorale: BWV 245/40

Let's look at the ways that chords lad to each other and fit into a phrase.

Repertoire needed for this lesson:

Bach chorale: BWV 17/7

Beethoven: Minuet, WoO 82

Mozart: Sonata, K. 311

Hymn Tune AZMON

The most common non-harmonic tones found in tonal music are the neighbor note and the passing tone.

The assignment for this lesson will be reviewed at the beginning of next lesson.

Repertoire needed for this lesson:

Bach chorale: BWV 17/7

Beethoven: Minuet, WoO 10 No. 1

Beethoven: Minuet, WoO 10 No. 5

Hymn Tune HYFRYDOL

When we see a 6/4 (second-inversion) chord, it almost always fits into a particular category. There are several types other than the cadential 6/4, and they each follow a particular formula.

The assignment for this lesson will be reviewed at the beginning of next lesson.

Repertoire needed for this lesson:

Beethoven: Minuet, WoO 10 No. 1

Hensel: Gartenlieder, Op. 3 No. 1

We begin our study of inverted chords with the first inversion of the dominant, because its bass note is a neighbor to the tonic.

Repertoire needed for this lesson:

Bach chorale: BWV 292

Mozart: Sonata, K. 311

The other inversions of the dominant seventh chord have voice leading that is equally straightforward.

Repertoire needed for this lesson:

Mozart: Eine Kleine Nachtmusik

Sibelius: Finlandia

C. Schumann: "Sie Liebten Sich Beide"

We finally get to start using the leading-tone triad, which is nearly always found in first inversion.

The assignment for this lesson will be reviewed at the beginning of next lesson.

Repertoire needed for this lesson:

Mozart: Ave Verum Corpus

Sibelius: Finlandia

Hymn Tune DIADEMATA

The tonic triad is also often found in first inversion.

Repertoire needed for this lesson:

Mozart: Eine Kleine Nachtmusik

C. Schumann: "Sie Liebten Sich Beide"

Hymn Tune DIADEMATA

The IV and ii chords are often found in first inversion. iii and vi, not so much.

Repertoire needed for this lesson:

Haydn: Symphony, Hob. I:92

Schubert: Minuet from String Quartet, D.112

The seventh chords besides ii and V are sometimes found in tonal music, usually in the same places we would expect to find their triad counterparts.

Repertoire needed for this lesson:

Mendelssohn: Song without Words, Op. 109

Mozart: Ave Verum Corpus

There are several varieties of non-harmonic tones besides the neighbor and passing tones.

There is no assignment for this lesson. The assignment for the next lesson will include material from this lesson.

Repertoire needed for this lesson:

Haydn: Symphony, Hob. I:92

Mendelssohn: Song without Words, Op. 109

Mozart: Eine Kleine Nachtmusik

C. Schumann: "Sie Liebten Sich Beide"

We finish our classification of the non-harmonic tones.

Repertoire needed for this lesson:

Bach chorale: BWV 386

Hensel: Gartenlieder, Op. 3 No. 1

Mozart: Concerto, K. 488

Mozart: Sonata, K. 311

Schubert: "An Emma"

Hymn Tune HYFRYDOL

Hymn Tune DIADEMATA

Today we learn to add non-harmonic tones into our chorale writing.

The leading-tone diminished seventh chord is technically not a diatonic chord, but it is naturally found within the harmonic minor scale.

Repertoire needed for this lesson:

C. Schumann: "Sie Liebten Sich Beide"

Sequences are an important compositional tool, but they often don't allow the composer to follow strict voice leading.

Repertoire needed for this lesson:

Hymn Tune HYFRYDOL

Today we start looking at the various ways phrases can be put together to create larger musical structures.

Repertoire needed for this lesson:

Beethoven: Minuet, WoO 10 No. 1

Beethoven: Minuet, WoO 10 No. 5

Haydn: String Quartet, Hob. III:62

Mozart: Sonata, K. 311

Schubert: Minuet No. 3 from String Quartet, D.89

Hymn Tune AZMON

Modulation is how composers change from one key or tonal center to another. They accomplish this in many ways. Most of them will be covered in Chromatic Harmony, but we learn about one of them today.

Repertoire needed for this lesson:

Mendelssohn: Song without Words, Op. 109

Now that we've learned about common-chord modulation, let's put it into context.

Repertoire needed for this lesson:

Bach chorale: BWV 17/7

Bach chorale: BWV 96/6

Bach chorale: BWV 386

Today we learn a new chord function, which will become an important focal point in the next course. Think of this as a preview.

Repertoire needed for this lesson:

Beethoven: Symphony No. 1

We put together everything we've learned in this course to create a complete analysis of an entire short piece.

Think of the assignment afterward as your final exam. Take your time, especially on the first section!

Repertoire needed for this lesson:

Bach chorale: BWV 245/40

Schubert: Minuet from String Quartet, D.112
