Quiz 1A – Music Definitions


Score:


1. Give an example of Music and Noise being created by each of the following sound-producing media: Use a different font or color.



A. Bird(s)


Music


We can find the music created by the sound of birds singing, from Concerto “Four Seasons” By Vivaldi. On the first movement, there is a part of trilling violins, which express the approaching of spring using sounds of birds singing. This came out as very harmonic and beautiful music.


Noise


The annoying sounds of birds chirping in the morning (mostly singing individually).


B. Two Pianos


Music


Two pianos can create beautiful harmonic sounds in the concertos. (Ex. Mozart concerto for two pianos K448)


Noise


Each piano playing an individual song at the same time could create noise.


C. Concert Band


Music


Harmonic performances that they perform under on conductor (lot of concertos for orchestras): under specific order, tempo, and rhythm.


Noise


Each instrument plays individually without any order. Ex) tuning before performance


D. Hand Claps


Music


Hand claps used for cheering for baseball and basketball. There is a certain order and tempo.


Noise


Sudden and loud hand claps during deep sleeping can interrupt our sense.


2. List three media (not musical) that produce low frequency sound. (under 100 Hz)


1. The sound of boat whistle (usually from big ships)


2. The sound from when earth surface is moving (earthquakes or erupting volcanoes)


3. Cell phone vibration


4. “Moo” sounds that cow makes


5. Sound from a thunder


3. List three media (not musical) that produce high-frequency sound. (above the piano 8KHz)


1. Whistling


2. The sound from scratching chalkboard using a fingernail


3. Noise from TV when it’s turned on (continuing Beep sound)


4. Fire alarm


4. List three media (not musical) that produce a regular pattern of sound and silence.


(Example: Heartbeat)


1. Microchronometer


2. Cursor on the computer screen


3. Blinking signal lights before signal changes


5. In comparing each pair of frequencies, put an ‘X’ by the one perceived (heard) as louder.


A. 500 Hz @ 50 dB_______ or 700 Hz @ 90dB____X___


B. 12 Hz @ 70 dB ___X_____ or 320 Hz @ 60 dB______


C. 21kHz @ 110 dB ___X____ or 440 Hz @ 60 dB______


D. 800 Hz @ 50 dB _____X__ or 600 Hz @ 30 dB______





6. The frequency of a fundamental (1st partial) is 110 Hz. Give the frequency of the following partials: 2nd partial = 220Hz., 3rd partial = 330Hz.


4th partial = 440Hz., 5th partial = 550Hz., 6th partial = 660Hz.


7th partial = 770Hz., 8th partial = 880Hz.


7. If the frequency of the 5th partial is 400 Hz, what’s the frequency of the fundamental? 80Hz. 4th partial? 320Hz.6th partial? 480Hz.,


10th partial? 800Hz.
