Study Notes
Sound is a phenomenon we experience every day — it's what we hear when someone talks or sings, or when music plays from our speakers. When sound waves reach your ear, they cause tiny vibrations inside of it, which your brain interprets as sound. One important aspect of sound is its pitch. Pitch refers to how high or low a sound is perceived by your ears. It can also refer to the frequency of a tone, expressed in terms like high pitched and low pitched. High pitches tend to be sharper while lower pitches can feel more deep and mellow.
Sound travels through the air in all directions, carrying energy with it. This type of wave gets shorter and longer over time because of how far away or close you are to the source of the noise. If you move closer to where the sound starts, it will get louder. But if you stand still, the sound won't change much unless something changes in the room, such as if there's some sort of ventilation system playing loud music nearby.
The pitch of sounds varies depending on many things, including their size, shape, temperature, and humidity. For example, if you blow into a bottle full of water and then put it back down again, it makes different kinds of sounds according to each one's length, width, depth, height, etc.. Similarly, different musical instruments have different tones due to differences in design. A guitar string produces higher-pitched notes because it has thinner strings that make smaller bumps along them. On the other hand, a piano key usually makes a deeper note because it has thicker metal rods underneath it.
Pitches become harder to distinguish between if they don't come in well defined chunks known as intervals. However, people generally recognize the difference between two pitches based mostly just on whether they go up or down after hearing both of them together once. Even so, most folks need help figuring out exactly what kind of interval they heard and why. There are several types of intervals used in music theory, such as minor thirds and major seconds. These tell us about the relative sizes and shapes of different sections of songs, helping musicians decide where to place certain chord progressions within pieces.
