+ Instrument Classifications Music Education – Laurentian University

+ SOUND SOURCES n Sound n occurs because air is caused to vibrate SOURCE: - a sound source is any object that causes air to vibrate n CAUSE: - Something needs to happen to CAUSE the sound source to vibrate n RESONANCE: - various objects vibrating in sympathy with a sound source

+ Musical Instrument Categories Hornbostel-Sachs Classification System n Membranophone n Chordophone n Idiophone n Aerophone n Quintaphone and subcategory, Electrophone

+ Membranophone n Sound is made by striking a ‘membrane’ or ‘skin’ stretched across an opening Examples: Various kinds of Drums

+ Chordophone n Sound is made by a string (chord) drawn taught over or from a resonating surface. Chordophones can be n plucked – banjo, guitar, harpsichord, etc. n Struck – birmbau, dulcimer, clavichord, piano, n Bowed – i. e. chord vibrates by causing FRICTION violin, viola, violincello, double bass, Also: tiger drum

+ Aerophone n Sound is made by vibrating air in a column or tube Examples: - air blows across the tube (traverse) flute, pop bottle, - whistle – recorder, bird calls - reed – clarinet, grass between your thumbs… kaan, mouth-organ - Double reed – oboe, bassoon - straw – (the L. U. Con-ed Vuvuzela!)

+ Idiophone n Sound source is unique to the instrument – - Many kinds of percussion instruments - Stones, bones, - Sound can be caused by ‘striking’, ‘scraping’, twirling, - -- essentially causing air to vibrate around the instrument…

+ Electronophones n • Sound is made through electronic means n • THERAMIN n http: //www. youtube. com/watch? v=w 5 qf 9 O 6 c 20 o&feature=related - Lev Theramin n • MOOG Synthesizer n http: //www. youtube. com/watch? v=yn. X 6 Wmvxl_8 - Robert MOOG n • Mellotron n Paul Mc. Cartney Demonstrates a Mellotron https: //www. youtube. com/watch? v=TUcf. B 5 Whp 4 I n • Digital Synthesizer MIDI

+ - Hydraulapohones - Plasmaphones - Quintephones n These are relatively new classifications n Instruments that produce sound from liquid state (water, heavy water) n Instruments that produce sound from matter in high energy state (fire, plasma) n • Instruments that create sound using non-electronic computation Digital Synthesizers – MIDI – electroencephalophones
