Classical

History and character

By “classical music” we mean, in the broad sense, the written European art tradition (and its offshoots around the world) from the Middle Ages to today; in the strict sense “Classicism” is only the period of Haydn, Mozart and early Beethoven. In this archive Classical music is organized by eras and schools, because each period has its own sound system, its own ensemble and its own forms: Renaissance (c. 1430–1600: vocal polyphony, church modes), Baroque (1600–1750: basso continuo, tonality, concerto and fugue), Galant and pre-Classical (c. 1720–1770: accompanied melody, galant schemata, birth of the symphony), Classicism (c. 1770–1820: sonata form, symphony, quartet, opera buffa), Early Romanticism (c. 1810–1850: lieder, piano pieces, virtuosity), Romanticism (c. 1850–1890: symphony and tone poem, chromaticism), Late Romanticism (c. 1890–1920: enormous orchestras, extended tonality), the great traditions of Italian and German opera, the Russian national school, French Impressionism and the 20th century with contemporary music.

Three threads run through all eras: the passage from modality (Middle Ages–Renaissance) to functional tonality (from the late 1600s) and then its dissolution (Wagnerian chromaticism, Impressionism, atonality, serialism, new modalities, spectralism, minimalism); the growth of the orchestra (from the Renaissance consort to the Baroque strings plus continuo, to the two-per-part Classical orchestra, up to the 100-plus players of Mahler and Strauss); and the evolution of forms, from the mass and the motet to the fugue and the concerto, to sonata form, the symphonic cycle, music drama, and the free and open forms of the 20th century.

For a producer, classical music is the reservoir of harmony, voice leading, counterpoint and orchestration on which film music, orchestral pop and much of the music theory taught today rest (Piston, Kostka-Payne, Aldwell-Schachter; Fux for counterpoint; Rimsky-Korsakov and Adler for orchestration). The scores of most of the repertoire up to the early 20th century are in the public domain and available free of charge on IMSLP; many reference recordings were made by labels such as Deutsche Grammophon, Decca, EMI/Warner, Harmonia Mundi, ECM New Series, BIS, Hyperion, Naxos.

Scales and keys

For classical music the “scales” field describes the tonal or modal system of each era. Roman numerals in minor relative to natural minor (in A minor F = VI, G = VII; the major V and the vii° of harmonic minor are written V and vii°).

Church modes (Middle Ages and Renaissance)

Eight modes (then twelve with Glarean, Dodecachordon, 1547), defined by finalis (final note), ambitus (range) and repercussio/tenor (reciting note). Authentic (ambitus from the finalis to the octave) and plagal (ambitus a fourth below the finalis).

• Musica ficta: unwritten accidentals (raised leading tone in cadences, Bb to avoid the F–B tritone: “mi contra fa diabolus in musica”). For this reason the Lydian with Bb in effect becomes a major scale.
• Use: Gregorian chant, the polyphony of Josquin and Palestrina, modal Lutheran chorales.

Major tonality (from the late 1600s)

• Formula 1 2 3 4 5 6 7; W W H W W W H. C major: C D E F G A B.
• Chords: I ii iii IV V vi vii°; functions: Tonic (I, vi, iii), Subdominant/predominant (IV, ii), Dominant (V, vii°).
• Characteristic note: the leading tone (B) rising to the tonic, the engine of the V–I cadence.

Minor tonality: three forms

• Natural (1 2 b3 4 5 b6 b7) — A minor: A B C D E F G. Chords: i ii° III iv v VI VII.
• Harmonic (1 2 b3 4 5 b6 7) — A B C D E F G#. Chords: i ii° III+ iv V VI vii°. Needed to have the major V and the leading tone.
• Melodic (ascending 1 2 b3 4 5 6 7, descending like the natural) — ascending A B C D E F# G#. Avoids the augmented second F–G# in melodies.
• In Baroque and Classical practice the three forms coexist in the same piece: melodic for the melody, harmonic for the harmony.

Chromaticism (from the late-16th-century madrigal to late Romanticism)

• Chromatic scale: 12 semitones. Use: lament (descending chromatic bass), expressive passages (Gesualdo), secondary dominants and altered chords (19th century), voice leading by semitone (Wagner, Tristan).

Symmetrical and “exotic” scales (19th–20th century)

• Whole-tone: 1 2 3 #4 #5 b7 — on C: C D E F# G# A# (Glinka, Debussy).
• Octatonic (tone-semitone / semitone-tone): C D Eb F Gb Ab A B or C Db Eb E F# G A Bb (Rimsky-Korsakov, Stravinsky, Messiaen mode 2).
• Pentatonic: C D E G A (Debussy, Puccini, the Russian school for “oriental” or folk color).
• Folk and national modes (Bartók, Janáček, Mussorgsky): Lydian, Mixolydian, Dorian, scales with an augmented second.

Beyond tonality (20th century)

• Free atonality (Schoenberg from 1908), twelve-tone technique (12-note row, Schoenberg from 1921–23), integral serialism (1950s), modes of limited transposition (Messiaen), microtonality and spectralism (Grisey, Murail), static diatonic tonality of minimalism.

How to orient yourself

Before 1600 think in modes and in intervals between the voices; between 1680 and 1900 think in keys and functions; from 1890 onward ask whether the piece uses an extended tonality, a symmetrical scale, a mode or a post-tonal system.

Harmony

From counterpoint to chord

• Renaissance: harmony arises from the meeting of the voices; perfect consonances (unison, fifth, octave) and imperfect ones (thirds, sixths), controlled dissonances (passing tones, prepared suspensions resolved down by step).
• Basso continuo (Baroque): the bass, figured with numbers (6 = first inversion, 6/4 = second inversion, 7, 4–3, ♯ for the major third), is realized extemporaneously by the harpsichord, organ, lute or theorbo. The music is conceived from the bottom up.
• Functional harmony (late 1600s to the 19th century): tonic – predominant – dominant – tonic; the rule of the octave and the partimento schemata teach how to harmonize each scale degree in the bass.

Cadences

• Perfect authentic: V(7)–I with the tonic in the soprano. Imperfect: V–I with the third or fifth on top or with inverted chords.
• Half cadence: pause on V (I–V, IV–V, ii6–V). Phrygian cadence: iv6–V in minor (in A minor Dm/F – E), typical of the Baroque between movements.
• Plagal: IV–I (“amen”). Deceptive: V–vi (in minor V–VI).
• Cadence with 6/4: I6/4–V(7)–I, where the 6/4 is a double appoggiatura over the V (formula of Classicism and of the solo concerto cadenza).

Modulations

• Closely related keys: dominant (I → V) in major, relative major (i → III) in minor, then IV, ii, vi.
• Techniques: common chord (pivot), secondary dominant, enharmonic modulation (vii°7 or German augmented sixth reinterpreted), modulation by chromatic mediant (Schubert, Beethoven), by sequence.

Altered and chromatic chords

• Secondary dominants (V/V, V/ii…), diminished sevenths.
• Neapolitan sixth (bII6): in C minor Db/F, before the V.
• Augmented sixths: Italian (Ab C F#), French (Ab C D F#), German (Ab C Eb F#) in C; the interval Ab–F# opens out to the octave on G (V).
• Tristan chord (Wagner, 1859): F B D# G#, enharmonically a half-diminished chord, which moves to E7 without resolving to the tonic of A minor.
• Chromatic mediants (Schubert, Liszt, Bruckner), ninth, eleventh, thirteenth chords, quartal chords (Scriabin, Schoenberg), polytonality (Stravinsky, Milhaud), clusters (Cowell, Ligeti).

Harmonic rhythm and density

Baroque: harmony that changes often (every quarter note or half bar), regular sequences. Classicism: slower harmonic rhythm in themes (one bar or more), acceleration toward the cadence. Romanticism: long pedals, continuous chromaticism, frequent modulations. 20th century: from Impressionist stasis to atonal density.

Typical progressions

Rhythm and groove

Meter, dance and pulse

• Renaissance: the tactus (hand beat, about 50–80 per minute) regulates the polyphony; mensural notation (tempus perfectum triple, imperfectum duple).
• Baroque: constant (“motoric”) pulse and stylized dances with precise meter and character: allemande (moderate 4/4), courante (3/2 or 3/4), sarabande (slow 3/4 with emphasis on the second beat), gigue (6/8, 12/8), minuet (3/4), gavotte (4/4 or 2/2 with a half-bar upbeat), bourrée (2/2 with a one-quarter upbeat), siciliana (pastoral 6/8 or 12/8), chaconne and passacaglia (3/4 over an ostinato bass). French practice: notes inégales (uneven eighth notes, almost swing) and the dotted rhythms of the overture.
• Classicism: periods of 4+4 bars, regular accompaniments (Alberti bass, repeated notes), minuet in 3/4, march, contredanse; syncopations and sforzandi as dramatic elements (Beethoven).
• Romanticism: rubato, agogic flexibility, waltz (3/4), polonaise and mazurka (Chopin), 3-against-2 and 4-against-3 polyrhythm in the piano.
• 20th century: irregular and constantly changing meters (Stravinsky, The Rite of Spring 1913), additive rhythms (Bartók “Bulgarian”, Messiaen), polyrhythms and continuous pulse (minimalism).
• Tempo: the Italian markings indicate character more than speed; the first systematic metronome markings are by Beethoven (after 1815).

Drums

The role of percussion in classical music

In classical music there is no drum set: the pulse is provided by the strings and the bass; percussion is color and structure.

• Timpani: they enter in the Baroque paired with natural trumpets (tonic and dominant, especially in D and C major: Bach, Handel), in Classicism they mark cadences and tuttis (Haydn, Symphony No. 103 “Drumroll”), with Beethoven they become protagonists (solo in the Violin Concerto, octave in F in Symphonies No. 8 and 9), in Romanticism they multiply and are tuned to different notes (Berlioz uses many in the Grande Messe des morts; pedal timpani spread in the late 19th century).
• “Turkish” (Janissary) band: bass drum, cymbals, triangle for the “alla turca” color in Classicism (Mozart, The Abduction from the Seraglio, 1782; Beethoven, finale of the Ninth).
• Romanticism and the 20th century: snare drum, bass drum, cymbals, tam-tam, glockenspiel, xylophone, celesta (Tchaikovsky, “Dance of the Sugar Plum Fairy”, 1892), bells, whip, wind machine (Strauss), percussion in its own right (Varèse, Ionisation, 1931, for percussion alone).

How they “think” rhythmically

• Timpani hits fall on strong beats, cadences and structural accents (start of the recapitulation, coda); the roll prepares the culminations.
• In dance the “rhythm section” is the bass with the chords on the upbeat (the waltz: bass on 1, chords on 2 and 3; the march: bass on 1 and 3, chords on the upbeat).
• In early and Baroque music performed today by historically informed ensembles, tambourine, drum and castanets are sometimes added in the dances: a reconstructed practice, not always documented in the score.

Typical mistakes (for those orchestrating in the DAW)

Timpani not tuned to the harmony, rolls without dynamics, cymbals on every climax, “film” percussion in an 18th-century context, timpani in piano passages where the Classical orchestra leaves them silent.

Bass

• Renaissance: the bass voice (bassus) is a line of the counterpoint, supported by viola da gamba, trombone (sackbut), dulcian, organ.
• Baroque: the basso continuo — cello or viola da gamba + violone/double bass + bassoon, with harpsichord, organ, theorbo or lute realizing the harmony from the numbers. It is the backbone of all the music.
• Classicism: cellos and double basses often in unison-octave (double basses sound an octave below the written pitch), clear harmonic bass, dominant pedals before the recapitulations, Alberti bass at the piano.
• Romanticism: cellos breaking away from the double basses with melodies of their own, tuba and contrabassoon, chromatic bass, long pedals (Bruckner, Wagner); the organ in the great finales.
• 20th century: ostinatos (Stravinsky, Orff), pedals, divisi double basses and extended techniques.
• Useful frequencies: double bass E1 ≈ 41 Hz (C1 ≈ 33 Hz with extension), cello C2 ≈ 65 Hz, bassoon Bb1 ≈ 58 Hz, tuba down to D1 ≈ 37 Hz, organ 32' down to 16 Hz.

Harmonic instruments

Ensemble by era

• Renaissance: a cappella voices; consorts of viols, recorders, cornetts and trombones; lute, harpsichord, virginal, organ, harp.
• Baroque: string orchestra (violins I and II, violas, cellos, double bass) plus continuo; oboes, transverse flute and recorder, bassoon, natural trumpets and timpani, hunting horns; harpsichord and organ for harmony.
• Classicism: orchestra “in pairs”: 2 flutes, 2 oboes, 2 clarinets (from the 1780s), 2 bassoons, 2 horns, 2 trumpets, timpani, strings; fortepiano.
• Romanticism: woodwinds in threes, four horns, trombones and tuba, harp, piccolo, English horn, bass clarinet, contrabassoon, percussion; modern piano (cast-iron frame, mid-19th century).
• Late Romanticism and the 20th century: 100+ players (Mahler, Strauss, Schoenberg Gurre-Lieder), then reduced ensembles (Pierrot lunaire, 1912), new instruments (celesta, saxophone, ondes Martenot, electronics).

Orchestral functions

Melody (violins, solo woodwinds, horns), inner harmony (violas, second violins, horns, clarinets, bassoons), bass (cellos, double basses, bassoons, tuba), color (harp, celesta, percussion). The classic reference text: Rimsky-Korsakov, Principles of Orchestration; for the modern era Samuel Adler, The Study of Orchestration.

Melody and vocals

• Renaissance: melody by stepwise motion and small compensated leaps, ambitus of an octave to a tenth, intelligible text (Palestrina), imitation between the voices; voices in 4–6 part polyphony (SATB and variants), falsettists and boy sopranos.
• Baroque: ornamented melody (trills, mordents, appoggiaturas), sequences, Fortspinnung (continuous development of a motif), da capo aria with variations in the repeat; virtuoso solo voices (castrati, sopranos), secco and accompanied recitative, choruses in 4–8 parts.
• Classicism: periodic phrases (4-bar antecedent + 4-bar consequent), singable and contrasting themes, instrumental “cantabile” melody, written-out ornaments; in opera ensembles and concerted finales.
• Romanticism: long, passionate melodies, broad arches, expressive chromaticism, lieder (voice and piano in dialogue), bel canto and then dramatic singing (Verdian, Wagnerian).
• 20th century: fragmented melody, wide intervals (Webern), modality and pentatonic (Debussy, Ravel), speech-song (Sprechstimme), extended vocal techniques (Berio, Sequenza III).
• Chorus: from Renaissance polyphony to the great symphonic chorus (Beethoven, Ninth; Verdi, Requiem; Mahler, Eighth “Symphony of a Thousand”). SATB registers: soprano C4–A5, alto F3–D5, tenor C3–A4, bass E2–D4 (comfortable choral ranges).

Instruments

Strings (violin, viola, cello, double bass; viola da gamba, violone, viola d'amore), woodwinds (recorder, transverse flute, piccolo, oboe, oboe d'amore, English horn, clarinet, bass clarinet, bassoon, contrabassoon, saxophone), brass (cornett, trombone/sackbut, natural and valved trumpet, natural and valved horn, tuba, cimbasso, Wagner tuba), percussion (timpani, bass drum, snare drum, cymbals, triangle, tam-tam, glockenspiel, xylophone, bells, celesta), keyboards (organ, harpsichord, clavichord, fortepiano, piano, harmonium), plucked strings (lute, theorbo, guitar, harp, mandolin), voice and chorus, electronics in the 20th century.

Drum patterns

Synths and sounds

• Piano V — Concert piano: For reducing and studying scores, playing the Romantic repertoire and accompanying voices; choose a grand piano model with mid-distance microphones for a “hall” sound.
• Augmented Strings — Study strings and layering: For sketching the string orchestration in the DAW; it does not replace a dedicated orchestral library, but it helps to try out voicings and dynamics.
• Augmented Voices — Study chorus: For hearing a four-part chorale or a choir pad under an orchestration.
• Mellotron V — Vintage strings, flutes and choirs: “Historical” orchestral colors for crossover or progressive arrangements of classical pieces.
• Modular V — 20th-century electronic music: For exploring the synthesis of Stockhausen and of the electronic studios of the 1950s–'60s: sine oscillators, filters, noise generators, envelopes.
• Synclavier V — Historic digital orchestration: The system used by composers and studios in the 1980s to orchestrate with FM and additive synthesis; useful for “glassy” timbres and bells.

Song structure

The main forms (details in the subgenres)

• Sacred vocal: mass (Kyrie, Gloria, Credo, Sanctus-Benedictus, Agnus Dei), motet, cantata, oratorio, passion, requiem.
• Secular vocal: madrigal, chanson, aria, lied, song cycle, opera (seria, buffa, grand opéra, music drama, verismo).
• Contrapuntal: canon, fugue (subject, answer, countersubject, exposition, episodes, stretti), ricercar, invention, chorale prelude.
• Over an ostinato bass: chaconne, passacaglia, ground.
• Dance and suite: allemande – courante – sarabande – (galanteries) – gigue.
• Concerto: concerto grosso (concertino and ripieno), solo concerto in ritornello form (Vivaldi), Classical concerto in sonata form with double exposition and cadenza.
• Sonata form: exposition (first theme in the tonic, bridge, second theme in the dominant or relative, codetta) – development – recapitulation (both themes in the tonic) – coda.
• Instrumental cycles: sonata, trio, quartet, symphony (Allegro in sonata form – slow movement – minuet or scherzo – finale).
• Variations, rondo (A–B–A–C–A…), ternary form (A–B–A), tone poem, character piece (nocturne, intermezzo, ballade), open and process-based forms in the 20th century.

Proportions

A minuet: 16 + 16 bars with repeats, trio of 16 + 16, da capo. A first movement of a Classical symphony: exposition 60–150 bars (repeated), development 40–150, recapitulation similar to the exposition, coda 10–100+ (Beethoven greatly lengthens development and coda).

Mixing and mastering

Sonic goal

Reproduce a performance in a real space: natural balance between sections, depth (front/back), stable and believable stereo image, faithful timbre, intact dynamics (from pp to ff). Mixing classical music is above all choice and placement of microphones: in post-production you do editing between takes, balancing, little EQ, additional reverb if the hall is dry, almost no compression.

Main microphone techniques

• Main pair: spaced A–B (two omnis at 40 cm–1.5 m), ORTF (two cardioids at 17 cm and 110°), XY (coincident cardioids at 90–135°), Blumlein (two figure-8s at 90°), MS.
• Decca tree for the orchestra: three omnis (traditionally Neumann M 50) about 3–3.6 m above the conductor, side pair about 1.5–2 m apart, center 0.6–0.8 m forward; with outriggers at the sides for width (developed at Decca by Roy Wallace and Arthur Haddy from 1954).
• Spots on sections and soloists, to be blended very low and time-aligned to the main pair (delay of about 2.9 ms per meter of distance).
• Ambient/room: distant pair toward the back for the hall tail.

Processing by section (approximate values, always in moderation)

• Strings: high-pass on the spot microphones (violins 80 Hz, violas 60, cellos 35, double basses 25); −1/−2 dB at 250–400 Hz if boomy; −1/−2 dB at 2.5–4 kHz if the spot is harsh.
• Woodwinds: high-pass 100 Hz; −1 dB at 1–1.5 kHz if the oboe is nasal.
• Brass: no compression; −1/−2 dB at 2–3 kHz if the trumpets sting in the spots.
• Solo piano: pair 1–2 m from the open lid + pair in the hall; −2 dB at 200–300 Hz if boomy, no gate.
• Voice and chorus: high-pass 80–100 Hz; very light de-esser; never obvious compression.
• Organ: distant microphones (the pipes are distributed), care for the low register (16–60 Hz) and the church noises.

Compression and dynamics

• No aggressive compression: the dynamics are part of the interpretation. You intervene with manual fader automation (following the score) and, if truly needed, with very slow and light compression (ratio 1.2–1.5:1, attack 30–80 ms, release 0.5–2 s, 1–2 dB) or delicate parallel compression.
• Limiter only as peak protection.

Reverb

First choice: the real hall. If needed, a high-quality algorithmic or convolution reverb (Bricasti M7 or emulations, Altiverb, Lexicon, Cinematic Rooms) with decay similar to the hall (1.8–2.5 s for orchestra, 2.5–5 s for chorus and organ in a church) and pre-delay 15–40 ms; filtered return (high-pass 150–200 Hz).

Orchestrating and mixing with virtual libraries (Spitfire, VSL, EastWest) in the DAW

• Choose a hall: use libraries recorded in the same space (Spitfire BBC Symphony Orchestra at Maida Vale, VSL Synchron in Vienna, EastWest Hollywood Orchestra) or “dry” libraries (VSL Synchronized Dimension, Sample Modeling) placed in a virtual hall (VSL MIR Pro, Altiverb).
• Library microphones: start from the Tree (Spitfire indicates it as the starting point of every mix), add Outrigger/Ambient for space and a little Close for definition. Same choice for all sections.
• Dynamics: CC1 = dynamics (crossfade between pp–ff samples), CC11 = expression/volume; draw crescendos and diminuendos, vary the dynamics on every long note. Velocity for the attacks of short notes.
• Articulations: keyswitches or separate tracks for legato, sustain, staccato, spiccato, pizzicato, tremolo, trills, mute; write the bowings like an orchestrator.
• Tempo and attacks: legatos and slow sustains have an attack delay (often 50–300 ms): anticipate the notes or apply a negative delay to the track (in FL Studio with the channel's time shift or by moving the notes), then check with the metronome.
• Layout: pan according to the orchestra's seating (violins I on the left, cellos and double basses on the right in the “American” layout; violins II on the right in the “European” one), depth with microphone balance or with MIR, not just with panning.
• Realism: do not write what an orchestra cannot play (ranges, wind breaths, bow changes). Double the strings only if the library does not have large enough sections.
• Buses: one bus per family (strings, woodwinds, brass, percussion, keyboards/harp, chorus) plus a common reverb; no limiter on the buses.

Master

• Approximate targets: orchestral and choral −23/−18 LUFS integrated (many commercial recordings fall between −20 and −16 LUFS), chamber music and piano −20/−16; short-term in fortissimos up to −10/−8; true peak −1 dBTP; LRA 10–20 LU. Platforms raise classical tracks little or not at all, but it is not worth squashing them to reach −14.
• Chain: minimal balancing EQ, possibly very slow “glue” compression, transparent limiter with long lookahead (e.g. FabFilter Pro-L 2 in Transparent mode) only on the peaks; fades and silences between movements handled with care (2–4 s).

Common mistakes

• Compressing or limiting to “raise the volume”.
• Spots too high: fake, close-up, harsh sound; spots not time-aligned (comb filtering).
• A different reverb for every instrument; reverb with too much bass.
• Cutting too much of the hall's low end (loss of warmth).
• In the DAW: flat dynamics, wrong articulations, late attacks, rigid quantization.
