Course talk:PHYS341/2018/project/antara

It is a nice article! Though, it might benefit from some additions and clarifications:

Overall:

• 1) It would be nice if you used consistent terms. For example, use only "panpipes" or "panflutes" throughout the article. As well, maybe you want to call the main parts either "pipes" or "tubes". It creates confusion when you use these words interchangeably.
• 2) Maybe combine "sound radiation" and "acoustics". It is confusing when the physics about the instrument is interrupted by the method of playing.

Intro:

• 3) Some image (illustration or a photo) is necessary because, the reader might not be familiar with how antara panpipes look like (had to google, you sometimes call the "panflutes" which is very confusing since they don't have holes).
• 4) You might want to add physical description of the instrument in the introduction (especially since you don't provide a picture). Only in the last section "sound radiation" is where the reader gets the image that pipes are attached in parallel and not some other way. I had to google what panpipes look like before reading the history section.
• 5) Instead of calling it "tube-based instrument of Peruvian origin", you might want to specify that this instrument belongs to wind instrument family and that sound is produced by blowing at one end of the pipe in the introduction. This would give a reader a rough idea of what it might be. Also, you might want to give an example of a similar instrument. Is flute similar or different? Is there any instrument that is roughly like panpipes or is this instrument very unique?

Structure:

• 6) "If the pipes are open, they produce a sound that is a higher octave than the closed pipes". Does it mean that panpipes can come in an open ended form? If you contrast it with other types of pipes, make it clear to the reader.
• 7) In the "acoustics" subsection of "structure" you refer to an article ("as this article reports"). Which article? Who wrote it? You might want to restructure this subsection so that the reader clearly knows what article you are referring to and what the reader needs to know from it. Maybe introduce an article at the beginning and summarize what the reader needs to know from it. Alternatively, you might just citation to this article without mentioning it like most of the Wiki articles do.
• 8) Can panpipes be made out of non-cylindrical pipes? Are there different variations of the panpipes?
• 9) What is a "decreasive tape"? Elaborate a bit more on the inverse relation of pipe length and frequency. Maybe give an example of how this relationship works.

Sound Radiation:

• 10) You might want to add explanation to the meaning "rarefaction" to make this article more clear to the reader. (Didn't know what it meant, had to google).

Whole article:

• The section titles don't have to include "of the Antara Panpipe"; e.g. "History of the Antara Panpipe" can just be "History".
• The article should have pictures and diagrams. Pictures of the instrument would probably help a lot with understanding the "Structure" section.

Introductory paragraph:

• "tube-based": what exactly does this mean? Use a technical term instead?
• "similar models": what does "model" mean here? Similar instruments? Similar how?
• "all over the world from Asia to North America": what parts of the world are not included? If it really is found everywhere, "all over the world" should suffice.
• "sound physics": maybe "acoustic properties" would be better?

History of the Antara Panpipe:

• "brought worldwide": word choice. "Distributed", "spread", "introduced to the rest of the world"?
• "has merged with other panflutes across America and Europe": What does this mean? The design changed and became indistinguishable from other panflutes? It influenced other panflutes so they became like the Antara panpipes? Both? Something else?

Structure of the Antara Panpipe:

• How are the pipes joined together? Are they arranged side by side? In a circle like the sheng?
• "increase in length gradually as the pipes increase in number": does this mean that each subsequent pipe is longer than the last? How much longer?
• "Since the panpipes are close at each end, when someone plays the instrument, the pipes produce a sound wave reflection": what does this mean? Please describe in technical terms.
• "If the pipes are open": at one end or both?
• "a higher octave": does this mean "an octave higher"? The fundamental is higher, or a different harmonic is most prominent?
• "A faster and easy method to fine-tune a panflute is to use rubber stoppers and corks": faster than what? How are the stoppers and corks used, exactly? How do they affect the pitch?
• "end-blown flute": what does this mean? How is this different from other kinds of flutes?
• "The length of each tube of the panpipe determines how the sound will be produced. Therefore, the length of the tube determines its fundamental frequency": this says the same thing twice. And what is the relationship between pipe length and fundamental frequency? What physically causes this phenomenon?
• "decreasive tape": "taper"? Does this mean a tapering/conical bore?
• "as the article reports": unnecessary. Cut this.
• "A narrow tube will sound "reedy", while a wide one will sound "flutey"": what does this mean in acoustic terms? High harmonics are more prominent, etc.?
• "A more exact method": more exact than what?
• "subtract this value from the tube length": using what units? Centimetres? Inches?

How to Use an Antara Panpipe:

• The Wikipedia style guide advises avoiding the use of "you". This section reads like an instruction manual rather than a description. Consider retitling it "Technique" or something similar and rewriting it accordingly.
• "duller": what does this mean in musical and/or acoustic terms? Lower fundamental frequency? Less high harmonics?

Sound Radiation

• "closed tube": closed at one end or both?
• "all of increasing length, connected parallel to one another": are the tubes connected as in air flows between them, or connected structurally? What does "increasing length" mean?
• "air particles are moved by a force": what force?
