This is because every human society and every culture has music as an integral part. 

It is also because there's no culture in the world that does not involve music, which is the unifying characteristics of human culture.

YES! Accurate response- Jenny, Aarthi, Akhil, Cathy, James, Elaine, Qin, and Claire. ]]> 2016-11-04 01:40:38 UTC https://padlet.com/rgoble/v6q0bz7w70d6/wish/135271992 rgoble https://padlet.com/rgoble/v6q0bz7w70d6/wish/135272071 The music instrument vibrates in a set, prescribed way, pushing the air in the environment of the instrument. This creates pulses through the air, which are actually fluctuations in air pressure.  The closeness of these pulses is called pitch.
Pitch--the quality of a sound governed by the rate of vibrations producing it; the degree of highness or lowness of a tone.
Pitch is presented by the frequency of air vibration around the instrument that was played, the higher the frequency, the higher the pitch is.

This should focus on the complete definition. Complete meaning the process.

This part is to emphasize the fact that we can hear sounds only because our brains can process them as sounds rather than vibrations of the air.

Elaine, James, Shari and David-- Yes, this is to show that pitch is a perceptual phenomenon. Nice work. ]]> 2016-11-04 01:42:41 UTC https://padlet.com/rgoble/v6q0bz7w70d6/wish/135272192 rgoble https://padlet.com/rgoble/v6q0bz7w70d6/wish/135272364 Octaves means the distance between the highest and lowest notes on an eight-note scale. Overtones are the higher frequencies that we can only hear one note instead of a series of notes. When we hear a series frequencies of one note, we can only hear the lowest frequency and overtones are the higher frequencies we assume it as one note.

An octave is one complete 8-note range. When two different frequencies, in which one is the double of other, we perceive it as the same note in the same pitch, except one octave apart. Overtones are all the higher double multiples of the fundamental frequency of one note, which is all perceived as one by the human ear.

Candice, Liqun, Akhil, Cathy, Jenny, Aarthi, Shari and David:
Good information - to be more precise: Octaves are Overtones, but Overtones include other notes that are not Octaves. Octaves occur when frequency is doubled. Overtones are all notes that are multiples of the original frequency.

In this passage, harmony refers to the combination of different musical notes played at the same time to produce a pleasing sound. Because harmonics produce harmonies so harmonics is key to harmonies.

Harmony refers to unity, and in this case, the unified way in which the notes are heard. In this context, they refer to the harmonized hearing of the 'harmonics', and it could be possible that some particular frequencies were called harmonics due to the similarity in notes heard by us.

Shari, David, Jenny, Aarthi, Qin, Claire, Akhil, and Cathy: This question is asked because harmony is related to timbre, which is the main component of music. It's also related to harmonics. We're just playing with different word forms. :)]]> 2016-11-04 01:48:40 UTC https://padlet.com/rgoble/v6q0bz7w70d6/wish/135272691 rgoble https://padlet.com/rgoble/v6q0bz7w70d6/wish/135272861 Harmonics are used to differentiate instruments and sound sources, which can be done by figuring out how instruments are amplifying sounds,  the contacts made by players to the instruments, and also the instrumental flux.

Harmonics can be involved in timbre and musical character such as perception of pitch, volume, duration of notes, speed of playing, which is the main characteristic we could use to distinguish different sounds in our daily life.

Our brain can perceive different overtones or harmonics, which one of the elements to help people to distinguish different sounds.

Good work, Jenny, Aarthi, Qin, Claire, James, and Elaine.]]> 2016-11-04 01:50:56 UTC https://padlet.com/rgoble/v6q0bz7w70d6/wish/135272861 rgoble https://padlet.com/rgoble/v6q0bz7w70d6/wish/135273180 To give an example of harmonics that the finger absorbs the fundamental frequency and leaves the harmonics  when we put a finger on a guitar string and plug it. Not that important for the whole article. The main idea of the article is discussing how human brain receive pitches and the factors making instruments' timbre different. Overtones are not that important when seeing this article as a whole.

Yes, a real life example, Natalie, Annie, Candice, and Liqun.]]> 2016-11-04 01:55:04 UTC https://padlet.com/rgoble/v6q0bz7w70d6/wish/135273180 rgoble https://padlet.com/rgoble/v6q0bz7w70d6/wish/135273427 122-137 is more important than 94-107. Because 94-107 only gives an example of harmonics, which is presented in the paragraph before. But 122-137 gives us a new idea about how shapes effect timbre.
The information about timbre is part of the main idea, so lines 122-137 is more important than lines 94-107.

Great answer, another real life example (Same as 10), Natalie, Annie, Candice, and Liqun. ]]> 2016-11-04 01:58:01 UTC https://padlet.com/rgoble/v6q0bz7w70d6/wish/135273427 rgoble https://padlet.com/rgoble/v6q0bz7w70d6/wish/135273594 No, it actually provided extra support for the purpose of harmonics.

No, it added further evidence and support for the other uses of harmonics by the brain.
No, it's just more extension of the previous text.

Right, not really, Jenny, Aaarthi, Qin, Claire, James and Elaine.

Yes there is evidence that these components are significant.
Loudness of overtones refers to the way an instrument amplifies or dampens harmonics. It is further influenced by the shape of instrument. We think the first group should delete this sentence: "volume,duration of notes, speed at which it can be played and the number of notes it can play concurrently" because this is the dimension of sound rather than that of timbre.
Other dimension of timbre should be duration of notes, speed at which it can be played and the number of notes it can play concurrently. Loudness of overtones, initial burst of sound and flux are three major dimensions. And yes, there is evidence that they are significant.

Nice! Good information, Akhil, Cathy, David, Shari, Natalie and Annie!]]> 2016-11-04 02:08:55 UTC https://padlet.com/rgoble/v6q0bz7w70d6/wish/135274582 rgoble https://padlet.com/rgoble/v6q0bz7w70d6/wish/135274804 It connects to the central idea of the article by saying that brain 's perception is the most important part and the components of sound are effected by the manner in which the brain processes these vibrations.
The same as the first group.

Akhil, Cathy, David, Shari, Natalie and Annie: Right, music is only music when it perceived by the human brain. Also, it's not just pitch and timbre--and even volume.

Elaine, James, Shari, and David- Right,. Perception: 30-4K Hz; Detection: 20->4K Hz.

Overtones are also involved in shaping a musical instrument 's tone or sound quality , called timbre.

Candice, Liqun, Akhil, Cathy, Jenny, Aarthi, Shari and David: Are overtones important to the perspective of speech? Possibly no. The brain eliminates the Overtones to detect the fundamental pitch. ]]> 2016-11-04 17:53:21 UTC https://padlet.com/rgoble/v6q0bz7w70d6/wish/135468294 rgoble https://padlet.com/rgoble/v6q0bz7w70d6/wish/135468497 They refer to a same thing: higher frequency sounds of the same note.
They are synonyms- higher frequencies of the note at fundamental frequency, perceived as the same note by us.
Agree with the first one.

Yes, synonyms, Shari, David, Jenny, Aarthi, Qin, Claire, Akhil, and Cathy.
