MUSIC 110 Online – Course Intro & Elements of Music (Lecture 1)

Elements of Music – Day 1 Lecture Highlights

Benefits of Listening to Music

• Activates nucleus accumbens → releases dopamine (feel-good neurotransmitter).

• Eases anxiety, boosts mood, aids sleep, motivates workouts.

• Physiological effects: reduced depression, stress relief, accelerated healing.

Approaches to Listening

1. Sensory/Passive – let sound “wash over”; day-dream state; minimal analysis.

2. Emotional – focus on feelings triggered; marketing & worship contexts often exploit this.

3. Story-Making – common for instrumental classical; listener invents narrative.

4. Critical Listening – analytical; attending to layers, structure, timbre, dynamics; requires practice & note-taking.

Physics of Sound

• Sound = mechanical wave generated by a vibrating object.

• Requires a medium (air) to travel.

• Demonstration: Ringing bell under glass vacuum becomes inaudible once air is removed.

• Music = “organization of sounds in time.”

Pitch Categories

• Definite Pitch – regular, measurable frequency (e.g., violin note).
  • Higher note ⇒ faster vibration.

• Indefinite Pitch / Noise – irregular vibrations (e.g., drum thud, cymbal crash).

Dynamics (Volume)

• Variations in loudness evoke emotion.

• Crescendo – gradual increase \big( < !!! < \big); anxiety-to-ecstasy arc.

• Sudden accents & whispered pianissimo also manipulate audience reaction.

• Historical masters: Mozart, Haydn, Beethoven.

Timbre / Tone Color

• “Personality” or quality of a sound.

• Descriptive vocabulary: raspy, dark, bright, distorted, nasal, pointed, round, piercing, metallic, clear, warm, resonant, breathy, gritty, etc.

• Audio Comparisons:

  • Rod Stewart vs. Michael Bublé (gritty vs. smooth-crooner).

  • Willie Nelson (nasal twang), Tina Turner (raspy power), Barry White (deep resonant bass), Adele (bright with vibrato).

Human Voice Classifications

• Women: Soprano (high) | Mezzo-soprano | Alto (low).

• Men: Tenor (high) | Baritone | Bass (low).

• Countertenor – male singing in falsetto (edge of vocal cords) ≈ female alto/soprano range.

• Historical Castrato – pre-pubertal castration to retain boy soprano; practice ended ≈ 1750.

• Vibrating object = vocal cords; powered by air flow → cannot phonate without breath.

Common Vocal Techniques & Styles

• A cappella – singing without instruments (e.g., 5-part National Anthem arrangement).

• Ornamentation / Melisma – decorating melody with improvised runs; widespread in gospel, R&B, medieval chant.

  • Example: Christina Aguilera’s embellished riffs; modern lineage from church/gospel traditions.

• Head Voice / Falsetto – lighter register produced on vocal-cord edges.

Practical & Ethical Implications

• Developing critical-listening heightens emotional intelligence, cultural literacy, and discrimination of sonic marketing.

• Ethical note: Historical castrato practice reveals power imbalance & bodily autonomy issues; modern study of music history must acknowledge such contexts.

• Instructor’s plagiarism statement reflects contemporary concern over AI & paid paper mills—integrity vital for true skill acquisition.

Numerical & Scientific References (LaTeX-formatted)

• Total course points: 200; A-range: 180 \leq P \leq 200.

• Extra-credit ceiling: +14 ⇒ P_{\text{max}} = 214.

• Frequency concept: f = \dfrac{\text{vibrations}}{\text{second}} (higher f ⇒ higher perceived pitch).
