timbre can be measured‚ unlike pitch and loudness‚ which can be rated on scales from “high” to “low”.(i) The commonly quoted American National Standards Institute formal definition of timbre reflects this: “Timbre is that attribute of sensation in terms of which a listener can judge that two sounds having the same loudness and pitch are dissimilar".(ii) In other words‚ two sounds that are perceived as being different but which have the same perceived loudness and pitch differ by virtue of their timbre

Theme: Pitch Perfect (Inspiration) The movie Pitch Perfect has many elements of inspiration that can be shown in many scenes. Inspiration is the underlying theme of the movie. One example would be when Beca first moved into college and started out as a DJ then later on started volunteering at the school’s radio room. She then starts to look at different clubs until she was spot on by a club called the Barden Bellas. The theme starts right when she starts being part of the Barden Bellas

in the hundreds. All in all‚ many similarities there are huge differences between soccer and basketball. The first and most noticeable difference between soccer and basketball is the size of the playing field. Soccer takes place on a large open pitch nearly 120 yards from end to end and about 50 yards wide. At either end of the field there are two large goals. These are quite large measuring eight feet high and 24 feet wide. The stadiums in which professional teams play are colossal. Some hold
