Latin

History and character

'Latin' is an umbrella term for the popular music of Spanish- and Portuguese-speaking Latin America and the Caribbean and of their diasporas (especially in the United States). At its base is the fusion of three heritages: the African traditions brought by enslaved people (polyrhythms, drums, call-and-response, timelines such as the clave and the tresillo), the European traditions (tonal harmony, guitar and string instruments, forms such as the song and the salon dance, the Spanish décima, the contredanse) and the Indigenous traditions (flutes, maracas, guacharaca, certain melodic modes, especially in the Andean and Colombian areas).

The major families: the Afro-Cuban (son, danzón, rumba, bolero, mambo, cha-cha-chá, then salsa and timba in New York and Havana), the Dominican (merengue, bachata, dembow), the Colombian (cumbia, vallenato, porro, champeta), the Brazilian (samba, choro, bossa nova, MPB, forró, funk carioca), the Río de la Plata (tango, milonga, candombe), the Mexican (mariachi, ranchera, corrido, norteño, banda, up to the corridos tumbados), the Puerto Rican (bomba, plena, then reggaeton) and the urban music of the 21st century (reggaeton, Latin trap, Latin pop). From the 1930s these musics spread around the world ('salon' rumba, Pérez Prado's mambo, the bossa nova of Jobim and Gilberto, Fania's salsa, the 'Latin explosion' of Ricky Martin and Shakira, the reggaeton of Daddy Yankee and Bad Bunny).

Cross-cutting elements: rhythm organized by a timeline (clave, tresillo, cinquillo, partido alto, bell pattern), percussive rhythm sections with fixed roles (conga, bongó, timbales, güiro, maracas, tambora, surdo, pandeiro), anticipated bass (tumbao) that ties bars together, guitars and pianos used as rhythmic instruments, call-and-response between soloist and chorus, two-part forms (song + improvised/danceable section such as the montuno). The harmony ranges from functional tonality with dominants and cadences (bolero, bossa, salsa) to modal loops (cumbia, reggaeton).

Scales and keys

Major (Ionian)

• Formula: 1 2 3 4 5 6 7 — W W H W W W H (semitones 2 2 1 2 2 2 1)
• Example on C: C D E F G A B
• Characteristic note: the 7 (leading tone) and the major 3: brightness and a strong V–I resolution
• Diatonic triads: C (I) – Dm (ii) – Em (iii) – F (IV) – G (V) – Am (vi) – Bdim (vii°)
• Seventh chords: Cmaj7 (Imaj7) – Dm7 (ii7) – Em7 (iii7) – Fmaj7 (IVmaj7) – G7 (V7) – Am7 (vi7) – Bm7b5 (viiø7)
• Use in the genre: much of son, cumbia, merengue, 'major' bachata, samba and Latin pop; functional I–IV–V harmony with secondary dominants.
• Real-world example: Buena Vista Social Club — Chan Chan (a minor-key progression, but many guarachas and sones are in major); many cumbias and merengues are built on I–IV–V.
• Common mistakes: ignoring the dominant: in son and salsa the V7 is fundamental and the bass tumbao anticipates it.

Harmonic minor

• Formula: 1 2 b3 4 5 b6 7 — W H W W H 1½W H (semitones 2 1 2 2 1 3 1)
• Example on A: A B C D E F G#
• Characteristic note: the 7 (leading tone) in minor and the augmented second b6–7: dramatic tension, 'Middle Eastern/Andalusian' flavor
• Diatonic triads: Am (i) – Bdim (ii°) – Caug (III+) – Dm (iv) – E (V) – F (VI) – G#dim (vii°)
• Seventh chords: Am(maj7) (i(maj7)) – Bm7b5 (iiø7) – Cmaj7#5 (III+maj7) – Dm7 (iv7) – E7 (V7) – Fmaj7 (VImaj7) – G#dim7 (vii°7)
• Use in the genre: the 'Latin' minor scale par excellence: bolero, tango, minor-key salsa, bachata, flamenco-pop; the major V (E7) and the i–iv–V7–i cadence.
• Real-world example: tango and bolero almost always cadence with the V7 of the harmonic minor; minor-key salsa uses i–iv–V7.
• Common mistakes: using natural minor in cadential passages: without the leading tone the Latin cadence loses strength.

Phrygian dominant (5th mode of harmonic minor)

• Formula: 1 b2 3 4 5 b6 b7 — H 1½W H W H W W (semitones 1 3 1 2 1 2 2)
• Example on E: E F G# A B C D
• Characteristic note: the b2 + major 3 pair (augmented second b2–3): the flamenco/Arabic sound par excellence
• Diatonic triads: E (I) – F (II) – G#dim (iii°) – Am (iv) – Bdim (v°) – Caug (VI+) – Dm (vii)
• Seventh chords: E7 (I7) – Fmaj7 (IImaj7) – G#dim7 (iii°7) – Am(maj7) (iv(maj7)) – Bm7b5 (vø7) – Cmaj7#5 (VI+maj7) – Dm7 (vii7)
• Use in the genre: Andalusian heritage: flamenco guitars, bachata and salsa intros, flamenco rumba, bolero; the Andalusian cadence Am–G–F–E (i–VII–VI–V) is the same scale seen from the V.
• Real-world example: the Andalusian cadence appears in countless Latin songs, from 'Malagueña' (Lecuona) to the pop of the Gipsy Kings.
• Common mistakes: calling the final E chord a 'dominant to be resolved': in the Andalusian cadence it is often the real tonic.

Dorian

• Formula: 1 2 b3 4 5 6 b7 — W H W W W H W (semitones 2 1 2 2 2 1 2)
• Example on D: D E F G A B C
• Characteristic note: the major 6 over a minor base: 'open' minor, less sad, which gives the major IV
• Diatonic triads: Dm (i) – Em (ii) – F (III) – G (IV) – Am (v) – Bdim (vi°) – C (VII)
• Seventh chords: Dm7 (i7) – Em7 (ii7) – Fmaj7 (IIImaj7) – G7 (IV7) – Am7 (v7) – Bm7b5 (viø7) – Cmaj7 (VIImaj7)
• Use in the genre: cumbia, Latin rock (Santana), Latin jazz, samba-jazz and timba use Dorian i–IV progressions; the major 6 brings light to the minor.
• Real-world example: Santana — Oye Como Va (an Am7–D9 progression in A Dorian, composed by Tito Puente).
• Common mistakes: playing the b6 in the melody of a Dorian vamp.

Mixolydian

• Formula: 1 2 3 4 5 6 b7 — W W H W W H W (semitones 2 2 1 2 2 1 2)
• Example on G: G A B C D E F
• Characteristic note: the b7 over a major base: 'earthy', festive major, without a leading tone
• Diatonic triads: G (I) – Am (ii) – Bdim (iii°) – C (IV) – Dm (v) – Em (vi) – F (VII)
• Seventh chords: G7 (I7) – Am7 (ii7) – Bm7b5 (iiiø7) – Cmaj7 (IVmaj7) – Dm7 (v7) – Em7 (vi7) – Fmaj7 (VIImaj7)
• Use in the genre: forró, baião, some cumbias and the guaracha and son vamps; the b7 without a leading tone gives an 'earthy' major.
• Real-world example: Luiz Gonzaga — Asa Branca uses melodies in a major mode with Mixolydian colors typical of the northeastern sertão (see the Forró entry).
• Common mistakes: confusing Mixolydian and Lydian dominant: in baião the #4 often appears as well.

Lydian dominant (Mixolydian #4)

• Formula: 1 2 3 #4 5 6 b7 — W W W H W H W (semitones 2 2 2 1 2 1 2)
• Example on C: C D E F# G A Bb
• Characteristic note: #4 + b7: a bright dominant; in Brazil it is the 'Northeastern scale' (Mixolydian with #4)
• Diatonic triads: C (I) – D (II) – Edim (iii°) – F#dim (iv°) – Gm (v) – Am (vi) – Bbaug (VII+)
• Seventh chords: C7 (I7) – D7 (II7) – Em7b5 (iiiø7) – F#m7b5 (ivø7) – Gm(maj7) (v(maj7)) – Am7 (vi7) – Bbmaj7#5 (VII+maj7)
• Use in the genre: the 'Northeastern scale' of forró and baião (C D E F# G A Bb) and a frequent color in bossa nova and Latin jazz over dominant chords (7#11).
• Real-world example: Tom Jobim often uses 7#11 chords (e.g. the D7#11 in the progression of 'Garota de Ipanema' in F: Fmaj7–G7–Gm7–Gb7), where the #11 is the color note.
• Common mistakes: using it over a major tonic chord with a major 7: Lydian dominant is for seventh chords.

How to choose among the genre's scales

• Afro-Cuban (son, salsa, mambo) → major or harmonic minor with clear dominants.
• Bolero, tango, bachata → harmonic minor (and Phrygian dominant for Andalusian colors).
• Cumbia, reggaeton, urban pop → Aeolian, Dorian, major over loops.
• Brazil (bossa, MPB) → major and melodic minor with extensions (maj7, 9, 11, 13); forró → Mixolydian and Lydian dominant.
• Rule: look at the cadence. If there is a V7–i it is harmonic minor; if the progression is modal and without a dominant, choose among Aeolian, Dorian and Mixolydian.

Harmony

Two major logics

1. Tonal-functional: bolero, tango, son, salsa, bossa nova, MPB. II–V–I cadences, secondary dominants, cycles of fifths, modulations to the relative or parallel key, chords with extensions (in bossa and modern bolero: maj7, m7, 9, 11, 13, b9).
2. Modal-cyclical: cumbia, vallenato, modern bachata, reggaeton, many folk forms. Loops of 2–4 chords (I–V, I–IV–V, i–VI–III–VII) repeated; the tension is in the rhythm and the voice.

Cross-cutting formulas

• Montuno / vamp: 2–4 repeated chords under the improvisation (I–IV–V–IV, ii–V, i–iv–V7–iv).
• Andalusian cadence i–VII–VI–V: Spanish heritage.
• i–iv–V7–i in minor: bolero, tango, salsa, bachata.
• Chromatic II–Vs and tritone substitutions in bossa and Latin jazz.

Harmonic rhythm and voicing

• Harmonic rhythm of 1–2 chords per bar in bolero and bossa; 1 chord every 1–2 bars in loops.
• The bass anticipates the chord (tumbao): the harmony 'arrives before' the downbeat.
• Piano and guitar play the chords in rhythmic figures (guajeo/montuno, bossa batida, rasgueo).

Typical progressions

Rhythm and groove

Timeline and clave

Many Latin musics are organized by a repeating timeline, often two bars long:

• Son clave 3-2: hits on 1, the & of 2, 4 | 2, 3 (in 4/4 on quarter notes; equivalent to 1, 1a, 2&, 3&, 4 in one bar of 2/2).
• Rumba clave: like the son clave but the third hit slides from the & of 2 to the a of 2 (in 2/2) — more tense.
• Tresillo: 3+3+2 sixteenth notes (1, 1a, 2&), the basis of habanera, tango, reggaeton, dembow.
• Cinquillo: ornamented tresillo (5 hits in a bar), typical of danzón, merengue, kompa.
• 6/8 bell pattern (Afro-Cuban): 7 hits in 12 pulses.
• Brazil: partido alto, telecoteco, bossa nova clave (like the son clave with the last hit shifted by a sixteenth note).

Feel

• Afro-Cuban: straight but with a strong sense of anticipation (bass and piano anticipate).
• Brazilian: 'swaying' sixteenth notes (light swing, not triplet-based) in samba and bossa.
• Caribbean/Colombian: 2/4 or 4/4 with the accent on the offbeat (cumbia) or on 1 (merengue).

Golden rule

Every instrument must be in clave: melodic phrases, fills and breaks must respect the direction of the timeline; a fill that is 'out of clave' sounds wrong to a Latin musician even if it is in time.

Drums

Concept

In most traditional Latin music there is no drum kit: there is a percussion section in which each instrument has a fixed role and the groove comes from the interlocking. The drum kit enters in Latin jazz, Latin rock, pop and modern orchestras, and when present it reproduces the functions of the percussion (bell on the ride, congas on the toms, cáscara on the shell, clave on the cross-stick).

Typical roles (Afro-Cuban)

• Clave: timeline (often implied, but everyone feels it).
• Conga/tumbadora: tumbao — slap on 2, open tones on 4 and the & of 4 (in 4/4), i.e. the offbeat 'heart'.
• Bongó: martillo (continuous eighth notes with an open tone on 4) in the verses; in the montuno the bongocero switches to the campana de mano (hand-held cowbell) in quarter notes.
• Timbales: cáscara (on the shell) in the verses, bell in the montuno and the mambo, fills and 'abanico' (opening roll) to signal sections.
• Güiro / maracas: continuous sixteenth or eighth notes, the glue.

Typical roles (other styles)

• Merengue: tambora (two heads, one played with a stick and one with the hand) + metal güira in eighth/sixteenth notes.
• Cumbia: tambor alegre, llamador on the offbeat, guacharaca in sixteenth notes, tambora.
• Samba: surdo (accent on 2), caixa, tamborim, pandeiro, agogô, cuíca, chocalho.
• Bossa nova: drum kit with cross-stick (bossa clave), kick in a surdo figure (1 and the & of 2 in 2/4), brushes on the snare.

Dynamics and interaction

• The percussion works on dynamic levels: verse (cáscara, martillo) lighter, montuno (bells) louder.
• The bass plays with the conga (tumbao) and anticipates the chords; the vocal and the chorus respond.
• The breaks (cierres, ponches) are played in unison by the whole orchestra, often on the 'ponche' of the clave (the & of 2 on the 3 side).

Typical mistakes

• Programming Latin percussion without a reference clave.
• Congas on 1 and 3: it is the opposite of the tumbao.
• Quantizing samba and bossa 100%: they lose their sway.

Bass

Principle

Traditional Latin bass (son, salsa, mambo) plays the anticipated tumbao: it avoids the downbeat of 1 and attacks on the & of 2 and on 4, tying the 4 over the barline. This way the chord of the next bar 'arrives early' and the groove pushes forward.

By style

• Salsa/son: tumbao (& of 2 and 4), root and fifth; baby bass (Ampeg) or upright bass.
• Bolero: bass on 1 and 3 or on 1 and &-of-2-3, with chromatic passing tones and light walking.
• Bossa nova: bass on 1 and the & of 2 (in 2/4, i.e. 1 and a dotted 3 in 4/4), alternating root–fifth, like the surdo.
• Cumbia: root on 1 and fifth on 3, sometimes with anticipation; 'bouncy' rhythm.
• Merengue: syncopated 'jaleo' bass between the tambora notes.
• Tango: marcato on 1 and 3 (marcato en cuatro) or a 3+3+2 figure (síncopa), arrastres (drags) before the hit.
• Reggaeton/urban pop: 808 or sub on the quarter notes or on the 3+3+2.

Harmonic instruments

• Piano: guajeo/montuno in octaves (salsa, son), offbeat chords (bolero), jazz voicings (bossa, Latin jazz).
• Tres cubano: guajeo in son.
• Guitar: bolero (trio, requinto), bossa (batida), bachata (requinto, segunda), flamenco (rasgueo), samba (7-string violão).
• Cuatro (Puerto Rico, Venezuela), charango (Andes), cavaquinho (Brazil).
• Accordion (vallenato, norteño, merengue típico, forró), bandoneón (tango).
• Strings (charanga, bolero, tango), horns (salsa, mambo, banda, mariachi).

Melody and vocals

Voice and melody

• Call-and-response: soloist (sonero, singer) and fixed chorus, especially in the montuno.
• Syncopated melodies aligned to the clave; phrases of 2 or 4 bars.
• Vocal romanticism (bolero, bachata): lyrical melodies, extensive use of appoggiaturas and chromaticism, intimate voice.
• Backing vocals in parallel thirds and sixths (bolero trio, salsa chorus), shouted unisons in the street genres.
• Vocal improvisation (inspiraciones, pregones) in the montuno.

Instruments

• Percussion: clave, conga/tumbadora, bongó, timbales, güiro, maracas, cowbell, tambora, güira, guacharaca, cajón, surdo, pandeiro, tamborim, agogô, cuíca, zabumba, triangle
• Bass: upright bass, baby bass, electric bass, tololoche, 808
• Harmonic: piano, tres, guitar, requinto, cuatro, charango, cavaquinho, 7-string violão, accordion, bandoneón, harp
• Winds and brass: trumpet, trombone, sax, flute (charanga), clarinet, tuba (banda)
• Strings: violins (charanga, tango, mariachi)
• Solo vocal and chorus

Drum patterns

Synths and sounds

• Piano V — Montuno, bolero, bossa piano: Bright grand piano for the guajeos; softer for bolero and bossa.
• Stage-73 V — Latin jazz and bossa Rhodes: Ninth and thirteenth chords, light tremolo.
• DX7 V — 1980s e.piano and FM basses: Salsa romántica, 1980s merengue, pop balada.
• B-3 V — Latin rock and boogaloo organ: Santana, Latin soul, 1960s boogaloo.
• Augmented Strings — Bolero and salsa romántica strings: Soft legato under the choruses.
• Jup-8 V — Latin pop pads and plucks: For urban and pop productions.

Song structure

Recurring forms

• Canción + montuno (son, salsa): a sung part (16–32 bars) followed by a cyclical chorus–pregón section (32–64+), with horn mambo and moña.
• Pop verse–chorus (Latin pop, reggaeton, modern bachata).
• AABA / ABAB form (bolero, bossa nova, tango), 32 bars.
• Dance forms with introduction and jaleo (merengue: paseo, merengue, jaleo).
• Narrative strophic forms (corrido, vallenato, décima).

Lengths

Phrases in multiples of 2 bars (aligned to the clave); sections of 8 or 16; instrumental intros of 4–16; codas with unison cierre.

Mixing and mastering

Sonic goal

It depends on the family. Traditional musics (son, salsa, bolero, bossa, tango) call for a dynamic and natural mix, with percussion well separated in the stereo field, clear horns and piano, warm bass and little bus compression. Urban musics (reggaeton, Latin trap, pop) call for a modern and compressed mix, with dominant 808 and vocal. References: Buena Vista Social Club (1997) for son, Fania All-Stars for salsa, João Gilberto for bossa, Despacito for urban pop.

Percussion (conga, bongó, timbales, güiro, maracas)

• Conga: HP 60–80 Hz, body 150–250 Hz (+2 dB if thin), slap 2–5 kHz; light compression 3:1, attack 10 ms; panning: conga on the right (+30/+50) in the classic 'from the audience' layout, or following the orchestra.
• Bongó: HP 150 Hz, +2 dB at 3–6 kHz, panned opposite the congas (−30/−50).
• Timbales: HP 100 Hz, bell +2 dB at 2–4 kHz; panning ±20–40; overheads/room that include them.
• Güiro/maracas: HP 500 Hz–1 kHz, side panning (±50–70), −6/−10 dB below the congas.
• Shared reverb (room or plate 0.8–1.2 s) to 'put the section in the same room'.

Bass (baby bass, upright, electric)

• HP 35 Hz, +2 dB at 80–100 Hz, note presence 700 Hz–1.2 kHz; opto compression 3:1 (3–4 dB). Mono, center.

Piano, tres, guitars

• Montuno piano: HP 80–100 Hz, +2 dB at 2–4 kHz to cut through; light compression; moderate stereo (not too wide).
• Tres and guitars: HP 100–150 Hz, presence 2–5 kHz; panning ±20–50.

Horns

• HP 120–150 Hz, −2 dB at 300–500 Hz, presence 2–5 kHz, de-esser if strident; light 3:1 compression; plate/hall reverb 1.5–2 s. Trumpets center-left, trombones center-right, saxes at the sides, or as laid out in the room.

Lead vocal and chorus

• Vocal: HP 80–100 Hz, −2 dB at 250–400 Hz, +2/+3 dB at 3–5 kHz; 4:1 compression (3–5 dB) + opto; plate 1.2–2 s at 12–20%.
• Chorus: more compressed, panning ±40–70, longer reverb.

Buses and groups

Percussion bus (light glue 1–2 dB), horn bus, rhythm section bus; in traditional styles, little bus compression.

Sidechain

Almost absent in traditional styles; in urban pop, kick → bass and kick → pad.

Master

• Traditional (salsa, son, bolero, bossa): −12/−9 LUFS integrated, true peak ≤ −1 dBTP, PLR 10–14 dB.
• Latin pop / urban: −8/−6 LUFS, PLR 7–9 dB.

Common mistakes

• Compressing the percussion until its dynamics disappear.
• All the percussion in the center.
• Bass that doesn't 'anticipate' because it is buried under the kick in Latin pop.
• Overly bright horns (strident at 3–5 kHz).
