Music Scales • Major: WWHWWWH (W:whole, H: half) • Minor: WWHWWHW • Several Subtypes of major scales, but more of minor • 2 constants in music: • A before middle C has frequence 440Hz • Ratio between half steps is 12th root of 2
Music and Mood • “International Language”: conveys emotion • Major keys: bold, uplifting • Minor keys: melancholy, ominous
Fast Rhythm/Tempo • Stimulates central nervous system (dance, movement) • Listen to exciting music for workouts • Listen to heavy metal when angry • Listen to punk/emo when sad or upset
Slow Rhythm/Temp • Triggers relaxation, sleepiness, etc. • Beethoven’s Moonlight Sonata makes people sleepy • Natural cds (Ocean, Forest, etc.) relax most • Lullabies: mothers sing to calm their children
Cultural Preferences • Western Music: typically Major scales • Chinese/Japanese Music: more Pentatonic scales • Indian music: Mohammedan scale/harmonic minor scale • Ancient Greek Scale had 5 notes • Approximately A, C, D, E, F (minor scale)
Consonance • Latin: com – with, sonare – sound • Definition: those sounds which seem “pleasing” to the ear • Frequency Ratios: lower simple numbers • Harmonic chord result of similar frequencies at different octave of the chord’s notes • Many definitions do not require exact integer tunings
Dissonance • Latin: dis – apart • “An unstable tone combination is a dissonance; its tension demands an onward motion to a stable chord. Thus dissonant chords are ‘active’; traditionally they have been considered harsh and have expressed pain, grief, and conflict.” – Roger Kamien • Temporary, transitional, in need of resolve
Resolution • Dissonance not always “unpleasant”, “grating” • All music with harmony or tone incorporates some degree of dissonance • Buildup and release of tension = dissonance and resolution
Harmony, Math, and Feelings C Major harmonics (emphasize each other) C Minor harmonics (missing correspondence creates darker feel)
Timbre of Music • Harmonic: proportion frequencies and inversely proportional amplitudes • Harmony or there lack of • Metal of brass (trumpet, tuba) rings inharmoiously • Woodwinds (saxophone, clarinet) more harmonious with many tones all played at once.
Timbre of Music (cont.) • Resonance • Conical (clarinet): even-numbered harmonics suppressed • Cylindrical (saxophone): even-number harmonics emphasized • Amplitude of sound waves • Loudness
Nature • Music appreciation is in many ways inherent I’m a raindrop. I’m a raindrop. I’m a raindrop, yes I am. But I’d rather be a raindrop than A drip.
"Babies come into the world with musical preferences. They begin to respond to music while still in the womb. At the age of 4 months, dissonant notes at the end of a melody will cause them to squirm and turn away. If they like a tune, they may coo.” - Willliam J. Cromie
Nurture • Cultural Context • Western: heptatonic scale (blues: hexatonic) • Chinese: pentatonic scale • Middle Easter: pentatonic • Indian (quarter tones instead of semitones) • All still made with the same system of cutting a string into the same fractions • Indian system has 12 notes with flats/inflection
Music and Medicine • While the Mozart effect (playing classical music and making babies smarter) may be a myth, there are many uses • Babies understand words better in song • Regulates blood pressure in patients and during exercise • Premature babies gain weight faster • Calms Alzheimer’s patients
Learning to Play and Learning • Music appreciation and understanding requires both hemispheres of the brain • Dr. Gordon Shaw and Dr. Frances Rauscher studied effects of teaching piano to one group of pre-schoolers and two groups of control subjects (one receiving computer lessons and the other no lessons) The group taught piano lessons scored 34% higher on spatial-temporal ability tests (indicates enhances in higher brain function required for math, chess, science, and engineering)
