Comprehensive Notes on Harmony, Texture, Form, Timbre (Transcript)
Harmony and the Musical Alphabet
Harmony focuses on the simultaneous combination of sounds, adding vertical depth to music. Central to most Western styles, it involves chords and chord progressions.
Chord: three or more notes sounded together.
Chord progression: a sequence of chords that creates unity in a piece.
Chords are built from scales.
Scale: a collection of pitches arranged in ascending order:
Octave: an interval spanning eight notes of the scale.
Triad: a three-note chord.
Melodies are harmonized with triads.
Tonic: the first note of the scale; acts as the home base for other notes.
Dissonance: a discordant, unstable combination of notes that creates tension and conflict; resolution moves toward consonance.
Consonance: a concordant, agreeable combination of notes; Resolution is relaxation or fulfillment after tension.
Western music is based on octave equivalence.
Pitches are letters A–G; there are twelve equal semitones (half steps) in an octave, forming the Chromatic Scale.
Sharp: raises a tone by a half step; Flat: lowers a tone by a half step.
Whole step: two half steps.
Scales, Tuning, and Key Concepts
Major and Minor Scales: defined by a specific pattern of whole (W) and half (H) steps; patterns begin on any pitch.
Major scale: pattern ; typically described as bright or cheerful with a triumphant sound.
Solfège: do-re-mi-fa-sol-la-ti-do.
Tension-resolution: the move from the seventh degree up to the octave (leading-tone to tonic) creates a sense of pull toward resolution.
Minor scale: pattern ; typically described as darker or sadder.
Minor involves lowering the third scale degree (flatted third).
Tonic–Dominant–Tonic: basic progression of harmony in many Western pieces.
Tonality (key): organization around a tonic; a basic principle of musical structure in much Western music from about 1600–1900.
Two poles of traditional harmony: Tonic (do) as the home base/rest; Dominant (sol) as the active, dominant function.
Diatonic vs Chromatic:
Diatonic: music clearly in a major or minor key, with melody and harmony rooted in the key; centers on the tonic and related harmonies.
Baroque and Classical era music were largely diatonic.
Musical Texture
Monophony: a single voice (sung or instrumental); one line of music without accompaniment.
Heterophony: a melody performed with an ornamented version of itself; several musicians sing or play the same line with slight variations in pitch or rhythm; may sound “out of sync"; common in non-Western cultures; jazz and spirituals often depend on heterophony.
Polyphony (many voiced): two or more melodic lines combined; based on counterpoint; one line set against another; requires more experienced listening.
Homophony: melody (primary focus) with accompanying harmonies; chords support the principal line; traditional and popular styles.
Homorhythmic: all voices move in the same rhythm; vertical conception where the melody is the most obvious line.
Contrapuntal devices (types of polyphony):
Imitation: melodic idea presented, then restated in another voice; may be brief or span an entire work; a common unifying technique in polyphony.
Strict imitation: exact repetition of a melodic idea in another voice.
Canon: each voice enters in succession with the same melody.
Round: perpetual canon (e.g., "Row, Row, Row Your Boat").
Musical Texture and the Listener: different textures require different listening approaches; with practice, listening becomes more nuanced.
Form: Organization and Design in Music (Part 2)
Form: organizing musical material (counting structure).
Vocal forms:
Strophic: same melody with each stanza of text.
Through-composed: no main section of music or text repeated.
Examples referenced: Madonna “Like a Virgin” and Frank Sinatra “Silent Night.”
Improvisation: pieces created spontaneously in performance; balanced by pre-established harmonic patterns, time frame, and melodic outline; common in jazz, rock, and some non-Western styles.
Binary and Ternary Form (Part 1):
Binary: two-part form (A–B) with a statement and departure.
Ternary: three-part form (A–B–A or other three-part structures).
Thematic building blocks:
Theme: main melodic idea used as a building block for a larger work.
Motive: a small fragment of a theme.
Thematic development: expansion of the theme.
Thematic development is necessary in larger forms to provide clarity, coherence, and logic.
Repetition and contrast principles:
Exact or varied repetition (melody, rhythm, or harmony).
Sequences: restatement of a theme at higher or lower pitch.
Call-and-response (responsorial music): leader answered by a chorus; origins in early Western church music and in African, Native American, and African American cultures.
Ostinato: short, repeatedly occurring musical pattern; unifying technique prevalent in blues, jazz, and rap (examples: references like “Still Dre”).
The Building Blocks of Form (Part 3):
Parts bound together to form a composition: notes, phrase, theme, section, movement, large-scale work.
Movement: a complete, independent division of a large-scale work.
Variation: aspects altered while the original tune remains recognizable.
Song as Union of Music and Words (Part 1):
Scat-singing: singing without words, nonlexical sounds, vocal improvisations in jazz (example: Ella Fitzgerald “Flying Home”).
Other historical forms: English madrigals, Christmas carols using vocalize or non-lexical vocalizations (e.g., “fa la la la la”).
Song as Union of Music and Words (Part 2): Anna Moffo “Vocalise” and related material; emphasis on wordless vocal expressions.
Texts, Text Settings, and Language in Sacred and Secular Music
Scared Music: music for worship, religious contexts; set in languages used historically in worship (Hebrew, Greek, Latin).
Latin: language of the Roman Catholic Church; medieval and Renaissance languages of learning.
Secular Music: nonreligious music; sung in the vernacular (language of the people).
Texts and text settings:
Often do not translate perfectly; composers set a variety of texts.
Common musical settings include:
Strophic form: same music for each stanza.
Text-setting styles:
Syllabic: each syllable receives one note.
Melismatic: a single syllable extended over many notes.
Neumatic: a few notes set to each syllable (middle ground).
Word-painting: music illustrates or emphasizes a textual meaning.
Musical Timbre (Tone Color)
Timbre: tone color or sound quality; what makes a sound distinct.
Timbre is influenced by size, shape, and proportions of an instrument.
The voice as instrument: the model for instrument builders, composers, and performers.
Vocal ranges: overview of high to low ranges in human voice; discussed as part of the voice-instrument relationship.
Lyric beauty and expressiveness: how timbre and voice convey emotion.
Vibrato: a throbbing effect used to add expression (example: “Nessun Dorma”).
The World of Musical Instruments (Part 1)
Instruments categorized by sound generation:
Aerophones: sound produced by air.
Chordophones: sound produced by vibrating strings (note: transcript cites a garbled form but this is the standard category).
Idiophones: sound produced from the substance itself (solid, self-sounding materials).
Membranophones: sound produced by a vibrating membrane (drums).
