Harmony, like the universe itself is all about relationships. We are alive right now on earth because of its relationship to everything else in our solar system. Any two notes played at the same time are considered harmony. Sound travels in waves that are measured in hertz. hertz measures how many waves per second a note is generating. The a string on a guitar, for example, vibrates 440 times per second, lower notes vibrates slower, and higher notes vibrate faster.
Human ears can hear in a range of approximately 31 hertz up to 18,000 hertz. Dogs, for example, can hear a much larger range, they can hear from 40 hertz, all the way up to 60,000 hertz. When two or more notes are played at the same time, the sound waves interact with each other creating two states Have dissonance and consonants, more commonly known as tension and release. Imagine the sound waves or like dolphins jumping in and out of the water. notes that are in dissonance for tension never line up evenly so that the pattern of the dolphins being in and out of the water is never in complete alignment. This is a physical event and why some people experience tension in music is very uncomfortable.
This technique is often used in movie soundtracks to enhance the sense of unease. consonants are released is having the dolphins come into a pattern where sometimes or all of the time they are at the top or bottom of their pattern together at the same time. Much like our preference for spicy or sweet tastes. We each have a sense of how much tension and release we like in our music and like a sense of taste. It can evolve over time. Depending on what we're exposed to the fact that there are no wrong notes is not just a spiritual state of mind, it's a fact.
All that exists is tension and release or dissonance and concepts, and how much you enjoy is entirely up to your own sense of personal taste. chords are organized harmony. Harmony is used most commonly to make up chords that are called triads. They're just simply chords that have three notes in them. chords are built like houses, there is a foundation, which we call the root, the third, which is like the main floor, and the fifth, which is like the second floor of the house. The root is the note that gives the court its name.
For example, in a C chord, the root is C. The third of the note is the third note In the scale, so C is one, D is two, n is three. The fifth is the fifth note in the scale, C is one, D is two is three, f is four, and g is five. There are several different types of chords. The two most common are major chords, and minor. What makes a chord major or minor is the relationship of the third to the root of the chord. When it is closer to the fifth than the route it is major, which is like moving the main floor of your house up slightly.
When it is closer to the basement or the route, it's minor. The way you move a note closer or further away is with sharps and flats to change a C chord from major Minor, you change the third, which is E to E flat. Most people experience major and minor chords by hearing them as happy sounds for major and sad sounds for minor. So always good to remember that music is a language that you were built to speak. And even when you're working on something that's a challenging concept. Just know that with enough time and practice, you'll be able to master it.
