Course talk:Phys341 2020/Railsback curve

Nice structure and contents, really fascinated to read those "own work" figures. I like how the author displayed the equal temperament frequencies in Hz, from A0 to C8, it really helped the audience like me who did not know much about piano. Another thing I like about this project is that the author explained the reason for the inharmonicity of the piano strings. However, I will like to see a bit more explanation on the Railsback curve and how does it work.

Railsback curve Notes

Overall, it is written very eloquently, there is not much to be said with regards to the main points outlined in the guidelines. With regards to some parts or some little details, I have a few minor comments:

• Maybe try writing a line or more about the beating heard, and where it originates from, when describing the analysis of common harmonics when tuning the piano
• (Very minor, but…) I would replace :

- “In theory, here is the tuning profile of a piano following a twelve-tone equal temperament tuning profile. (see Figure 1, Figure 2)”

- With (or something along the lines of):

- “Figure 1 and 2 illustrate the tuning profile of a piano following a twelve-tone equal temperament.”

• I find the use of the word acute a bit strange in the context of inharmonicity. I would suggest to use pronounced
• Very nice conclusion in my opinion, I don’t have much more to add aside from what is said above.
