🎵 Year 8 Music

Composition & Structure

Musical Forms and Structures

• Binary form (AB): two contrasting sections. Each section is repeated (AABB). Used widely in Baroque dance music.
• Ternary form (ABA): a theme, a contrasting middle section, and a return to the opening. Common in Classical pieces (minuets and trios, da capo arias).
• Rondo form (ABACADA…): a recurring main theme (refrain) alternates with contrasting episodes. Common in Classical and Romantic music.
• Theme and variations: a melody is presented and then modified in each variation (change of rhythm, key, tempo, harmony, texture, ornament, mode).
• 12-bar blues: the foundation of blues, jazz, and rock. A repeating 12-bar harmonic structure using chords I, IV, and V.
• 32-bar AABA form: the classic Tin Pan Alley and jazz song structure: 8-bar A, 8-bar A, 8-bar B (bridge), 8-bar A.
• Verse-chorus: the dominant structure of pop music. Verse develops the story; chorus provides the hook and emotional peak. Pre-chorus, post-chorus, bridge, middle 8 are common additions.
• Through-composed: no repeating sections; the music continuously develops (common in opera and art songs).

Compositional Devices

• Ostinato: a repeated rhythmic or melodic pattern (riff, ground bass). Creates momentum and hypnotic drive.
• Sequence: a motif repeated at a different pitch (ascending or descending). Used extensively in Baroque music.
• Pedal note: a sustained or repeated note (usually in the bass) over which harmonies change. Creates tension.
• Imitation: one part repeats or echoes the melody of another part shortly after. If strict and continuous: canon (or round).
• Inversion: a melodic shape turned upside down (what went up now goes down). Used in Baroque counterpoint and 20th-century serialism.
• Augmentation / Diminution: a melody presented in longer / shorter note values. Classic development technique in fugues.
• Fragmentation: breaking a theme into its component motifs and developing them independently.

Harmony & Chord Progressions

Building Chords

• A triad = root + major 3rd + perfect 5th (major chord) OR root + minor 3rd + perfect 5th (minor chord)
• 7th chord: a triad + a 7th interval. Dominant 7th (V7) has a major 3rd, perfect 5th, and minor 7th. Very common in jazz and blues.
• Chord inversions: 1st inversion (3rd in the bass), 2nd inversion (5th in the bass). Inversions create smoother bass lines and less "thuddy" progressions.
• Diatonic chords: the chords built on each degree of the scale, all using only notes from that scale. In C major, the diatonic triads are: I=C, II=Dm, III=Em, IV=F, V=G, VI=Am, VII=Bdim

Common Chord Progressions

• I–IV–V–I: the most fundamental progression in Western music; used in blues, folk, gospel, country, classical cadences
• I–V–VI–IV: the "four-chord song" (C–G–Am–F in C major). Used in hundreds of pop songs. Axis of Awesome demonstrated this famously.
• I–VI–IV–V: the "50s progression". Used in classic rock and roll and ballads.
• II–V–I: the fundamental jazz progression. Dm7–G7–Cmaj7 in C major. Creates strong resolution through dominant tension.
• VI–IV–I–V: minor key pop; also called the vi–IV–I–V progression in major terms. Melancholic, commonly used in pop ballads and film music.
• 12-bar blues in C: C–C–C–C | F–F–C–C | G–F–C–G (bars 1–12)

Cadences

• Perfect cadence (V→I): strong, conclusive sense of ending. The musical equivalent of a full stop.
• Imperfect cadence (any→V): ends on the dominant — sounds unfinished, like a question. Creates expectation.
• Plagal cadence (IV→I): "Amen" cadence; softer, more settled conclusion than perfect cadence. Common in hymns.
• Interrupted cadence (V→VI): the "surprise" cadence — the ear expects V→I but gets VI instead. Avoids the cadence; creates surprise and continuation.

Music Technology & DAWs

The DAW (Digital Audio Workstation)

• A DAW is software for recording, editing, mixing, and producing music digitally
• Common DAWs: GarageBand (free, Mac/iPad), Audacity (free, any platform), Logic Pro (Mac, professional), Ableton Live (popular for electronic/live performance), FL Studio (popular for beat-making), Pro Tools (industry standard for studios)
• The DAW interface: tracks (MIDI and audio), timeline (arrange window), mixer, plugins (effects and virtual instruments)

MIDI vs Audio

• MIDI (Musical Instrument Digital Interface): not sound itself — a data protocol. Records which note, how loud, how long, and what instrument. Can be edited, transposed, quantised, and assigned to any sound after recording.
• Audio recording: records actual sound waves (via microphone or line input). Fixed once recorded (must be processed to edit pitch/timing). WAV and AIFF are uncompressed (high quality); MP3 and AAC are compressed (smaller file).
• Modern productions typically use both: MIDI for virtual instruments (drums, keys, strings), audio for recorded vocals and live instruments

Key Production Concepts

• Quantise: snapping MIDI notes to the nearest grid line (beat/sub-beat) to correct timing — can also be set to 50–80% to retain a human feel
• Equalisation (EQ): adjusting the volume of specific frequency ranges. Cut unwanted rumble (low-end), muddy mids, or harsh highs. Boost to enhance character.
• Reverb: simulates the acoustic space of a room (cave, hall, bathroom). Small rooms sound intimate; large halls sound epic.
• Delay: echo effect — delays a copy of the signal. Used for depth and rhythm effects. Slapback delay was central to early rock and roll.
• Compression: reduces the dynamic range (gap between loudest and quietest). Makes the mix sound louder and more controlled. Overcompression (the "loudness war") can sound fatiguing.
• Panning: placing sounds in the stereo field (left, centre, right) to create width and separation in a mix
• Mixing: balancing all individual elements — volume, panning, EQ, effects — into a cohesive whole
• Mastering: the final processing step; prepares the final stereo mix for release across different playback systems

Classical & Orchestral Music

The Orchestra

• The modern symphony orchestra has four sections: strings (violins I & II, violas, cellos, double basses), woodwind (flute, oboe, clarinet, bassoon), brass (horn, trumpet, trombone, tuba), percussion (timpani, snare, cymbals, glockenspiel, xylophone)
• The conductor coordinates the ensemble using a baton: sets tempo, shows phrasing, cues entries, shapes dynamics
• The leader (concertmaster) is the principal first violinist; gives the tuning note (A, 440 Hz) at the start

Western Classical Music Periods

• Baroque (c.1600–1750): ornamental, contrapuntal (multiple independent melodic lines), harpsichord continuo. Key composers: J.S. Bach, Handel, Vivaldi, Purcell. Key forms: fugue, concerto grosso, suite, oratorio. Terraced dynamics (sudden changes, not gradual).
• Classical (c.1750–1820): balanced, elegant, clear phrase structure (antecedent-consequent), Alberti bass, gradual dynamics. Piano replaced harpsichord. Haydn, Mozart, early Beethoven. Key forms: symphony, string quartet, sonata, concerto. Sonata form is the defining structural principle.
• Romantic (c.1820–1900): emotional expression, nationalism, expanded orchestra, extreme dynamics, programme music. Beethoven (late), Schubert, Brahms, Tchaikovsky, Wagner, Liszt, Dvorak, Elgar. Development of the symphonic poem. Opera became huge.
• Modern/20th century: Impressionism (Debussy, Ravel — atmosphere, whole-tone scale), Expressionism (Schoenberg — atonality, 12-tone technique), Neoclassicism (Stravinsky, Prokofiev), Minimalism (Philip Glass, Steve Reich), Spectralism and beyond.

Sonata Form (First Movement Form)

• The fundamental organisational principle of Classical and Romantic instrumental music
• Exposition: introduces two contrasting themes in different keys (Theme 1 in tonic, Theme 2 in dominant). Repeated. Transition (bridge) modulates between them.
• Development: themes are developed, fragmented, and explored through different keys. Creates instability and tension.
• Recapitulation: themes return, both now in the tonic key. Resolves the tension created in the development.
• Sometimes includes an introduction (slow) before the exposition and a coda after the recapitulation.

Musical Theatre & Film Music

Musical Theatre

• Musical theatre combines drama, song, and dance to tell a story; the songs advance the plot or reveal character
• Key elements: the book (script/dialogue), lyrics, music, choreography, set, costume, lighting
• The "11 o'clock number": the big emotional climax number near the end of Act 2
• The "I Want song": establishes the protagonist's desire near the beginning — e.g. "Part of Your World" (The Little Mermaid), "Somewhere That's Green" (Little Shop of Horrors)
• Key musicals and composers: Les Misérables (Claude-Michel Schönberg), Phantom of the Opera (Andrew Lloyd Webber), Hamilton (Lin-Manuel Miranda — incorporates hip-hop and R&B), West Side Story (Leonard Bernstein), Chicago (John Kander)
• Sondheim (Stephen Sondheim, 1930–2021): the most influential composer-lyricist of the late 20th century; known for complex, psychologically nuanced characters and sophisticated music (Sweeney Todd, Into the Woods, Company)

Film Music (Soundtrack)

• Film music serves the narrative — it guides the audience's emotional response, establishes setting and atmosphere, signals character, and provides continuity
• Leitmotif: a recurring musical theme associated with a character, place, or idea. Pioneered by Wagner in opera; used extensively by John Williams (Star Wars, Indiana Jones, Schindler's List — each character has identifiable themes).
• Diegetic sound: sound that exists within the world of the film (characters can hear it) — a radio playing, a live band on screen
• Non-diegetic sound: sound added for the audience only (characters cannot hear it) — the orchestral score, a narrator's voiceover
• Mickey-mousing: when music precisely synchronises with on-screen action (e.g. musical stabs matching a character's falls). Common in cartoons; can seem comedic in drama.
• Source music: background music with an implied source (a café, a party) — a form of diegetic sound
• Temp track: temp music placed against picture during editing; the composer may be asked to match its feel — controversial as it can limit creative freedom
• Notable film composers: John Williams, Ennio Morricone, Hans Zimmer, Bernard Herrmann (Psycho — strings-only score), Ennio Morricone, John Barry, Danny Elfman
