This website is “The Washington Post” and it is very helpful because it has very helpful images, diagrams and information. 1985 – 2002 was the era of tapes to watch videos, 2003 – 2014 was the era of DVDs to watch videos and 2015 + is the era of digital videos. In 2006 94% of homes bought DVDs. On the internet it was different. Until 1993 no households had internet. 1994 – 1999 55% of households had internet. From 2000 – 2005 34% of households had internet but it was slow. 2006 + 86% of households have internet. There are many more examples this website provides such as music. Down below are how phones have developed over 30 years.

Module One Post Ten (Mathematics In Music In Movies)
This video sums up the mathematics in the music that is placed into a film or movie. Without music or sound effects the movie would be more boring. There is counting, rhythm, scales, intervals, patterns, symbols, harmonies, time signatures, overtones, tone, pitch and much more to make a piece of music sound right.

Module One Post Eight (Connections: Film: Shots, Cuts, And Editing)
This link is a good resource because it goes through the different types of shots, cuts, and editing methods and what they are exactly. It also talks about the sound and music in films and how they attract the audience as well.

Module 1 Post 10 [ Math and music]
This page briefly talks about the Mozart Effect. The Mozart Effect is a phenomenon that happens when young people listen to a wide variety of Mozart’s different pieces while studying. It’s said that this helps students to memorize and remember things during class. I’ll use this page to gain some extra knowledge on things I might not have covered.
Module 1 Post 9 [ Math + Music]
This page talks about physics and logarithm in music. It states that the piano body shape was created with a logarithm graph. All scales are based off of math, examples include: Chromatic scale (up every half-step) and Pentatonic scales (Scales with 5 notes). I will use this site to get information on the physics behind music.
Module 1 Post 8 [ Musical pitches and math]
This site talks about musical pitches. The frequency determines how high or how low a pitch can sound, for example: The pitch of a high D ( Or D5) is 587.33 Hz while a low pitch such as a low C (C0) is 16.35 Hz. The pitch of a standard A (A4) rests at 440 Hz. Most people tune with A4. The ending statement of the article states that some musicians can slowly gain a degree of perfect pitch ( Being able to sing each individual note, improvise, compose by ear etc.) just by being familiar with A4 note.
Module 1 Post 7 [ Math and the Musical Form]
This site explains musical forms like AABB, ABA, AABA and many others. Musical form determines how a piece can sound based on repetition. Forms usually depend on a statement and restatement type of melody ( Question to answer compositions) and also contrast. I will use this site as a place to gather extra knowledge. I know this page is trusted because there are citations and the last update was pretty current ( October 31)
Module 1 Post 6 [ Pythagorean tuning]
This Wikipedia page explains how Pythagorean tuning uses math ( frequency ratio and intervals) to determine how high or how low a note is based on the vibrations per second. The faster it is, the higher the note is. The lower the vibrations are, the lower the note is. I will use this site to further understand the Pythagorean tuning method.
Module 1 Post 4 [ The Mathematics of Music ]
This site talks about pitch, octaves and harmonies. I think this site is a good place for me to study my subject because the author, Jeffrey Rosenthal, is a professor in the Department of Statistics (DoS) at the University of Toronto. In one section of this article, it states that the reason some notes work well and some don’t. ( Example: C and G sounds good while C and E flat don’t sound well) This is because mathematics decide whether they sound good or not. Each note has a different pitch and frequency that determines if they are compatible with other notes. All notes can sound good under context (It all depends on the key of the piece).
Module 1 Post 3 [ Frequency modulation and music synthesis ]
Frequency modulation and music synthesis
This article comes from the AMS (American Mathematical Society). The article talks about wave frequencies and also Frequency Modulation. When we hear noises (music) our brains are processing the sound waves. They also state that sound is created by different types of air pressure. Frequency Modulation is just that. Modulating a signal so that it matches another signal. I want to use this article to study the perception of music and noises
