= Introduction =

'''Music Theory and Harmony''' is the study of how musical sounds are organized and how notes work together. In this Grade 9–10 aiMOOC, you will connect written notation, scales, intervals, chords, chord progressions, cadences, and voice leading. You will not only learn terms: you will listen, analyze, perform, compose, and explain why a musical passage creates stability, motion, tension, or release.

Music theory is a set of tools for describing patterns that musicians use. It does not tell you that one style of music is “correct.” Different musical traditions organize pitch, rhythm, texture, and harmony in different ways. This course focuses mainly on '''tonal harmony''' as it is commonly taught in Western staff notation, while encouraging you to compare these ideas with the music you already know.

[[File:Music notation.svg|500px|frameless|center]]

The image above shows several basic elements of staff notation. As you work through the course, use a keyboard, guitar, digital piano, notation app, or any instrument available to you. If you do not play an instrument, you can still sing, clap, use a virtual keyboard, or work with notation and listening examples.

== Learning Goals ==

By the end of this aiMOOC, you should be able to explain and apply the main ideas of [[English:Music theory|music theory]] and [[English:Harmony|harmony]]. You should be able to read basic staff notation, recognize scale and chord patterns, build triads, label common chords with Roman numerals, identify harmonic functions, compare common cadences, follow individual voices through a chord progression, and create a short harmonic composition of your own.

You should also be able to justify your musical choices. For example, instead of saying “this chord sounds good,” you should be able to explain that a dominant chord creates expectation because of its position in the key, that a leading tone tends to move toward the tonic, or that smooth voice leading lets individual parts move by small intervals while the harmony changes.

= Foundations: Pitch, Staff, Rhythm, and Meter =

{{BR}}
== Pitch and Note Names ==

A '''pitch''' is the perceived highness or lowness of a sound. In the note-naming system used in this course, the letter names A, B, C, D, E, F, and G repeat in higher and lower octaves. On a piano keyboard, the repeating pattern of black keys helps you locate these notes.

An '''octave''' is the interval from one note to the next note with the same letter name, such as C to the next C. The higher note has twice the frequency of the lower note when both are tuned in the usual octave relationship. Musicians often treat notes separated by octaves as closely related, even though they are not identical in pitch.

[[File:Piano keyboard and clefs.svg|500px|frameless|center]]

{{BR}}
== The Staff and Clefs ==

The '''staff''' has five horizontal lines. Notes can be placed on lines, in spaces, or on short ledger lines above or below the staff. A '''clef''' tells you which pitches belong to the staff positions.

The '''treble clef''' is common for higher registers, including many melodies and the right hand of piano music. The '''bass clef''' is common for lower registers, including bass instruments and the left hand of piano music. Middle C sits between the two staves when they are combined as a grand staff.

[[File:Treble clef and Bass clef.svg|500px|frameless|center]]

{{BR}}
== Accidentals and Key Signatures ==

A '''sharp''' raises a written pitch by one semitone, and a '''flat''' lowers it by one semitone. A '''natural''' cancels a sharp or flat in the relevant notated context. Enharmonic notes, such as F-sharp and G-flat on an equal-tempered keyboard, can sound at the same pitch while having different spellings and harmonic meanings.

A '''key signature''' places sharps or flats near the clef to show which note spellings are normally altered in a key. Accidentals inside a measure can temporarily change notes outside that key signature.

{{BR}}
== Note Values, Rests, and Meter ==

Harmony unfolds through time, so rhythm matters. A note value indicates duration relative to the beat, while a rest represents measured silence. In common notation, whole, half, quarter, eighth, and sixteenth notes form a proportional system of duration.

[[File:Music rests.svg|500px|frameless|center]]

A '''time signature''' organizes beats into measures. In 4/4, four quarter-note beats normally fill a measure. In 3/4, three quarter-note beats fill a measure. In 6/8, six eighth-note subdivisions are often felt as two larger beats, each divided into three. Meter affects how listeners hear strong and weak positions, which can influence harmonic rhythm and cadence placement.

'''Harmonic rhythm''' means the rate at which chords change. A song may keep one chord for a full measure, change twice per measure, or use an irregular pattern. The same chord progression can feel very different when its harmonic rhythm changes.

{{BR}}
= Scales, Keys, and Tonality =

{{BR}}
== The Major Scale ==

A '''scale''' is an ordered collection of pitches. The major scale follows the step pattern whole, whole, half, whole, whole, whole, half. Starting on C and using only white piano keys gives C major: C, D, E, F, G, A, B, C.

The notes of a scale are called '''scale degrees'''. In a major key, scale degree 1 is the '''tonic''', the tonal center. Scale degree 5 is the '''dominant'''. Scale degree 7 is the '''leading tone''' because it lies a semitone below the tonic and often moves upward to it.

[[File:C major scale with degrees and tones.svg|500px|frameless|center]]

{{BR}}
== Minor Scales ==

Minor keys use several related scale forms. The '''natural minor''' scale has the pattern whole, half, whole, whole, half, whole, whole. The '''harmonic minor''' raises scale degree 7 compared with natural minor, creating a stronger leading tone and usually a major dominant chord. The '''melodic minor''' form is treated differently in different traditions; in classical theory, scale degrees 6 and 7 are commonly raised when ascending and restored to the natural-minor form when descending.

For harmony, the raised seventh degree in harmonic minor is especially important because it strengthens the pull from dominant harmony to the tonic. For example, in A minor, G-sharp can lead upward to A.

{{BR}}
== Keys and the Circle of Fifths ==

A '''key''' gives a piece or passage a tonal center and a network of pitch relationships around that center. Major and minor keys can share the same key signature. These are called '''relative keys'''. C major and A minor are relative because neither key signature has sharps or flats.

The '''circle of fifths''' arranges keys so that neighboring major keys differ by one sharp or flat. Moving clockwise through major keys usually adds sharps; moving counterclockwise usually adds flats. Relative minor keys can be shown alongside their major relatives.

[[File:Circle of Fifths.svg|500px|frameless|center]]

The circle is useful for predicting closely related keys, remembering key signatures, and seeing why certain chord roots often move effectively by fifths.

{{#ev:youtube|https://www.youtube.com/watch?v=_LHv5WN4SiU|500|center}}

{{BR}}
= Intervals: Measuring the Distance Between Notes =

An '''interval''' is the distance between two pitches. To name an interval, first count letter names inclusively to find the interval number. C to E spans C-D-E, so it is some kind of third. Then compare the number of semitones or the note spelling to determine its quality.

Common interval qualities include '''perfect''', '''major''', '''minor''', '''augmented''', and '''diminished'''. Unisons, fourths, fifths, and octaves use perfect as their basic quality. Seconds, thirds, sixths, and sevenths use major or minor.

[[File:Intervals.svg|500px|frameless|center]]

Intervals matter because they are the building blocks of melodies and chords. A major third plus a minor third creates a major triad. A minor third plus a major third creates a minor triad. The perfect fifth appears in many stable-sounding chord structures.

'''Consonance''' and '''dissonance''' are context-dependent ways of describing relative stability and tension. They are influenced by musical style, tuning, register, timbre, spacing, and cultural expectations. Do not treat them as universal labels for “pleasant” and “unpleasant.”

{{BR}}
= Chords and Triads =

{{BR}}
== Building Triads by Stacking Thirds ==

A '''chord''' is a group of notes understood as sounding together or functioning together. A '''triad''' contains three chord members arranged as a root, third, and fifth. You can build a triad by choosing a root and stacking two thirds above it.

Four common triad qualities are:

# [[English:Major triad|Major triad]]: A major third from root to third plus a perfect fifth from root to fifth.
# [[English:Minor triad|Minor triad]]: A minor third from root to third plus a perfect fifth from root to fifth.
# [[English:Diminished triad|Diminished triad]]: A minor third from root to third plus a diminished fifth from root to fifth.
# [[English:Augmented triad|Augmented triad]]: A major third from root to third plus an augmented fifth from root to fifth.

[[File:Major and minor triads, triangles.png|500px|frameless|center]]

Try this on C. C-E-G is a C major triad. C-E-flat-G is a C minor triad. C-E-flat-G-flat is a C diminished triad. C-E-G-sharp is a C augmented triad.

{{BR}}
== Root Position and Inversions ==

A chord is in '''root position''' when its root is the lowest note. In a triad, '''first inversion''' places the third in the bass, and '''second inversion''' places the fifth in the bass. The chord identity remains based on the root even when the bass note changes.

Inversions matter because they shape the bass line, spacing, and voice leading. A progression can sound smoother when the bass does not leap to every chord root.

{{BR}}
== Diatonic Triads in a Major Key ==

If you build a triad on every degree of a major scale using only notes from that key, the qualities follow a stable pattern:

# [[English:Tonic chord|I]]: major
# [[English:Supertonic chord|ii]]: minor
# [[English:Mediant chord|iii]]: minor
# [[English:Subdominant chord|IV]]: major
# [[English:Dominant chord|V]]: major
# [[English:Submediant chord|vi]]: minor
# [[English:Leading-tone chord|vii°]]: diminished

Uppercase Roman numerals usually indicate major triads, lowercase numerals indicate minor triads, and the degree symbol indicates diminished quality. Roman numerals are useful because they describe a chord's position and function in a key rather than only its letter name.

{{BR}}
== Diatonic Triads in Minor ==

Natural minor produces the basic triad pattern i, ii°, III, iv, v, VI, VII. In tonal harmony, however, the seventh scale degree is often raised. That change can turn v into a major V chord and create a diminished leading-tone chord vii°. These altered chords strengthen dominant-to-tonic motion.

Because minor-key harmony can draw from natural, harmonic, and melodic minor resources, you should expect more pitch variation than in a simple natural-minor scale.

{{BR}}
= Harmonic Function and Roman Numerals =

'''Harmonic function''' describes the role a chord plays in creating stability, departure, preparation, tension, and return. A useful Grade 9–10 model groups many tonal chords into three broad functions.

The '''tonic function''' creates or confirms a sense of home. I is the clearest tonic chord in major, and i is the clearest tonic chord in minor. The vi chord can sometimes substitute for tonic-like stability in major, although it is not identical to I.

The '''predominant function''' prepares dominant harmony. IV and ii are common predominant chords in major. The term “subdominant function” is also used in some teaching traditions, especially for IV and related harmonies.

The '''dominant function''' creates strong expectation for the tonic. V and vii° contain scale-degree tendencies that point toward tonic harmony. The leading tone normally wants to resolve toward scale degree 1, and scale degree 4 often moves downward to 3 in a V–I resolution.

[[File:Circle of fifths with key signatures and triads.svg|500px|frameless|center]]

A common functional path is '''tonic → predominant → dominant → tonic'''. This is not a rule that every piece must follow, but it is a powerful model for understanding many tonal phrases.

{{BR}}
= Chord Progressions =

A '''chord progression''' is an ordered series of chords. Chord progressions create larger harmonic motion and can support melodies, bass lines, grooves, and formal sections.

[[File:Chord progression.png|500px|frameless|center]]

In C major, the progression I–IV–V–I is C major–F major–G major–C major. It begins at the tonic, moves away, builds dominant tension, and returns home. Another widely used progression is I–V–vi–IV. Its loop does not always create a strong final cadence, so it can keep musical motion going for many repetitions.

Root motion by descending fifth or ascending fourth is common in tonal harmony. For example, D minor to G major to C major forms ii–V–I in C major. This motion is especially important in classical, jazz, gospel, and many popular styles, though each style uses it differently.

{{#ev:youtube|https://www.youtube.com/watch?v=v3YbEL-_eoI|500|center}}

{{BR}}
== How to Analyze a Progression ==

Use this process when you analyze harmony:

# [[English:Find the key|Find the key]]: Look at the key signature, important ending notes, repeated tonal centers, and cadences.
# [[English:Spell each chord|Spell each chord]]: Identify the notes sounding at the same time or implied by the texture.
# [[English:Find the root|Find the root]]: Rearrange the chord mentally into stacked thirds if necessary.
# [[English:Label the Roman numeral|Label the Roman numeral]]: Compare the chord root and quality with the scale degrees of the key.
# [[English:Describe the function|Describe the function]]: Decide whether the chord acts mainly as tonic, predominant, dominant, or another color.
# [[English:Explain the motion|Explain the motion]]: Track the bass, melody, tendency tones, common tones, and cadence.

If one chord does not fit the key, do not assume your analysis is wrong. The music may use a borrowed chord, secondary dominant, chromatic passing harmony, modal mixture, or a temporary change of key.

{{BR}}
= Cadences: Musical Punctuation =

A '''cadence''' is a harmonic and melodic pattern that closes or pauses a phrase. Cadences can function like punctuation: some sound final, some unfinished, and some surprising.

An '''authentic cadence''' moves from dominant harmony to tonic harmony, usually V–I in major or V–i in minor. In some school systems, V–I is called a '''perfect cadence'''. In U.S. theory, the more specific term '''perfect authentic cadence''' describes a strong V–I ending with both chords in root position and the tonic in the highest voice at the end.

A '''half cadence''' ends on V and therefore sounds open or unfinished. In some British teaching traditions, this general idea is often called an '''imperfect cadence'''.

A '''plagal cadence''' moves IV–I and is often associated with a gentler closing effect. A '''deceptive cadence''' usually moves V to vi in major, avoiding the expected tonic. In some traditions this is called an '''interrupted cadence'''.

{{#ev:youtube|https://www.youtube.com/watch?v=SIcFOkMtDJI|500|center}}

When identifying a cadence, listen to the melody as well as the chord roots. A strong sense of closure depends on rhythm, phrase position, bass motion, melody, voicing, and musical style.

{{BR}}
= Voice Leading and Part Writing =

'''Voice leading''' is the way individual musical lines move from one harmony to the next. Imagine a four-part texture as four singers. Even when the chord label changes, each singer still needs a singable line.

Useful voice-leading strategies include keeping common tones in the same voice when practical, moving other voices by step or small interval, resolving tendency tones clearly, and avoiding unnecessary leaps. Contrary motion between outer voices can create independence.

In common-practice four-part writing, parallel perfect fifths and parallel octaves are usually avoided because they reduce the independence of voices in that style. This is a '''style convention''', not a universal law. Parallel fifths, octaves, and doubled lines are used deliberately in many other musical traditions and genres.

When V moves to I in C major, the leading tone B often resolves up to C. The note F in a G7 chord often resolves down to E. These semitone movements are important parts of the dominant-to-tonic sound.

{{#ev:youtube|https://www.youtube.com/watch?v=UkatcvIuF4U|500|center}}

{{BR}}
= Melody, Non-Chord Tones, and Harmonic Context =

A melody does not have to use only chord tones. '''Non-chord tones''' can create motion, decoration, and controlled tension.

A '''passing tone''' fills the space between two stable notes by step. A '''neighbor tone''' moves away by step and returns to the same note. A '''suspension''' holds a note from the previous harmony so that it briefly creates dissonance before resolving, often downward by step.

When you harmonize a melody, look for strong-beat notes, repeated notes, phrase endings, and longer durations. These tones often help define the harmony, while shorter notes between them may function as passing or neighbor tones.

A useful test is to ask: '''Which notes belong to the chord, and which notes are moving through or decorating it?''' This prevents you from changing chords every time the melody contains a non-chord tone.

{{BR}}
= Consonance, Dissonance, and the Harmonic Series =

Musical sounds usually contain a fundamental frequency plus partials. In an idealized harmonic series, partial frequencies occur at whole-number multiples of the fundamental. Some simple frequency relationships help explain why octaves and perfect fifths can fuse strongly in many acoustic contexts.

[[File:Harmonic Series.png|500px|frameless|center]]

However, harmony is not explained by acoustics alone. Musical training, style, tuning system, instrumentation, register, rhythm, and cultural expectation all shape what listeners hear as stable, tense, rough, smooth, familiar, or surprising. A dissonance can be expressive and desirable; its role matters more than a simple “good versus bad” label.

{{BR}}
= Ear Training and Listening =

Theory becomes useful when you can connect symbols to sound. You can train your ear without perfect pitch. '''Relative pitch''' means hearing relationships between notes, such as recognizing that one note is a perfect fifth above another or that a chord progression moves from dominant to tonic.

Practice short listening cycles. First, sing or play the tonic. Next, listen for the bass. Then decide whether the harmony feels stable, departing, preparing, tense, or resolved. Finally, test your guess on an instrument or with notation.

For intervals, compare a new sound with a reference you can sing accurately. For chords, learn the contrast among major, minor, diminished, and dominant-seventh qualities. For cadences, focus on the final two harmonies and the melody's last note.

{{BR}}
= Composition Lab: Build an Eight-Measure Harmonic Study =

Create a short eight-measure piece in C major, G major, F major, A minor, or another key you understand. Begin by choosing a meter and a simple harmonic rhythm. Use at least four different chords and include a clear cadence at the end.

A possible planning method is to make the first phrase establish the tonic, let the middle measures move through predominant and dominant functions, and make the final phrase return clearly to the tonic. You may use a repeated chord loop if you can explain how it affects the sense of closure.

Write a melody that includes both chord tones and at least two controlled non-chord tones. Then revise the bass line or chord inversions so that at least some voices move by step or remain on common tones.

Your finished work can be notation, a MIDI sequence, a live recording, a DAW project, or a written chord-and-melody chart. Add a short explanation naming the key, Roman numerals, cadence, and one voice-leading choice.

{{#ev:youtube|https://www.youtube.com/watch?v=_eKTOMhpy2w|500|center}}

{{BR}}
= Common Misunderstandings =

'''“Every song has to stay in one key.”''' No. Music can tonicize other chords, borrow notes, use modes, modulate, or avoid functional tonality altogether.

'''“Minor always sounds sad and major always sounds happy.”''' No. Mode can affect color, but tempo, rhythm, register, timbre, melody, dynamics, lyrics, and cultural context strongly influence expression.

'''“A chord is defined by its bass note.”''' No. The bass can be the root, third, fifth, or another chord tone. Inversions change the bass while the chord root remains the same.

'''“Dissonance is a mistake.”''' No. Dissonance can create energy, direction, color, and expression. Many styles depend on carefully placed dissonance.

'''“Roman numerals tell you the exact voicing.”''' No. They identify scale position and chord quality, but a single Roman numeral can be realized in many registers, inversions, spacings, and instrumental textures.

{{BR}}
= Summary =

Music theory gives you a vocabulary for describing patterns. Harmony explains how simultaneous or implied pitches interact and how chords move through time. Scales organize pitch collections, intervals measure distance, triads build basic chord structures, Roman numerals show a chord's place in a key, functions explain harmonic roles, cadences shape phrase endings, and voice leading connects chords through individual lines.

The most useful habit is to connect '''symbol, sound, and musical purpose'''. Whenever you learn a theoretical idea, play or sing it, listen for its effect, find it in real music, and use it in a small composition of your own.
