+# 33-114: Physics of Musical Sound
+
+| Category | Difficulty |
+|:-:       | :-:        |
+| HW       | 3          |
+| Exams    | 4          |
+
+This class is composed of 3 major sections. The first covers basic acoustical physics, such as properties of waves and  harmonic motion. The second section is a detailed discussion of tuning theory and systems, and the math thereof. The final section covers the physics of musical instruments, covering the major families and some high level physics of each, along with the human voice and ear. There is also a brief discussion of room acoustical design. 
+
+## Homeworks
+
+The HW in this class are fairly straightforward. It will be important to have some record of the equations discussed in lecture, as for most lectures notes are not passed out.
+
+## Exams
+
+Exams are also straightforward. There are 3 exams, one for each section of the course. The third exam takes place during the time scheduled for the final, but is weighted the same as other exams. 
+
+## Lectures
+
+Attendance is randomly taken during lecture, usually with a short quiz. Answers to the quiz come from readings in the textbook or from class material.
+
+## Fulfillments
+
+This course falls into the Science and Engineering courses category for CS students, and counts as a math/science elective for engineering students. (Although it used to count for one of the engineering gen ed categories, it no longer does.) It is also a required class for an audio engineering minor. 
+
+## Applicability
+
+Much of the course content is more technical than many musicians need, and is not particularly closely aligned with any core fields of engineering. However, it does provide some useful intuition and practice with decibels. There are also connections to fourier series, although this class is at far less of a technical level than 18-290. 
+
+## Prior Experience
+
+No prior musical experience is necessary, although the ability to read sheet music and very basic music theory (i.e. basic chords and intervals) is beneficial and may save time on homework and exams. 
+
+## Resources
+
+- The recommended textbook is _Why You Hear What You Hear_. It is not extremely closely aligned with the course's content, as it is not the original textbook, which is no longer available. One does not necessarily need it for success.

+# 57-173: Survey of Western Music History
+
+| Category | Difficulty |
+|:-:       | :-:        |
+| Exams    | 1          |
+| Homeworks| 1          |
+
+This class provides an extremely broad history of Western Music, stretching from Gregorian chant and earlier to the present day. It is accompanied by listening assignments for each week. 
+
+## Homeworks
+
+There are not traditional homework assignments in this course. Instead, there is a list of terms each week that should be researched and defined, and will be expanded upon and occassionally verbally quizzed in class. They also form the basis for the exams. There are also weekly listening assignments in the companion course, 57-188. On the final, there will be a question asking for the percentage of music listened to. 
+
+## Exams
+
+Exams are straightforward, and typically consist of multiple choice questions followed by an essay on topics discussed in class. The mutliple choice questions are closely related to the definition of terms, while the essay question will require more complex thought and analysis. 
+
+## Lectures
+
+Attendance is randomly taken through Canvas quizzes during most lectures, although questions are not difficult. Lecture may include lecturing on material, group excrercises, and watching and listening to musical performances. Students will also occasionally be asked to define terms. 
+
+## Fulfillments
+
+This course counts as PPC general education class for students in CIT, and a cultural analysis class for those in SCS. It is also a required course for an audio engineering minor. 
+
+## Applicability
+
+Course content is not particularly aligned to any technical field, but students with an interest in music history may find it interesting.  
+
+## Prior Experience
+
+No prior musical experience is necessary.
+
+## Resources
+
+- The recommended textbook is _Music: The Definitive Visual History_. It may make defining terms slightly easier, but much of the information can be found online. The textbook is also available at local libraries.
