What is Harmony The Math Behind Music Harmony Definition Music Lessons
Hi everyone! Konnichiwa! My name is KatMcDowell, I'm a singersongwriter born in Japan and raised in New Zealand. Today I'mvisiting Socratica Studios to talk to you about harmony. To show you how harmony works, let's use the opening notes of my song â€œHumanâ€�.â™« It's just one of those days.I don't want to get out of bed.quot;To hear the full version of this song, I made a music tutorial with Socratica. So come checkit out on my channel later.
To start, let's listen to the opening notes.â™« So.Nice and harmonious, righté But what if we used different notesâ€¦â™« Oh, bleegh! Why does that sound so wrong,when the original sounded so goodé The reason is harmony.Every musical note is connected to a number its frequency. For example, the note â€œAâ€�has a frequency of 440 hertz.â™« When I play this note, â™« the air between usvibrates back and forth very quickly, 440 times each second! This causes your eardrumto vibrate, and your brain says, â€œHey! That's
an A!â€�So here's the basic idea behind harmony. Two notes sound good together â™« when their frequenciesform a simple fraction. For example, the notes C and G sound good together. â™« And their frequenciesare in the ratio 3 to 2. I know, I know, it's not exactly. The ratiois really, really close to 3to2, it's just a tiny bit off. Most people can't hearthe difference. The reason why it's not exactly 3to2 is a story for another day. The notes C and F also sound good together. â™«The ratio of their frequencies is 4 to 3. Another simple fraction, another pleasantsound.
Ooh! Listen to this pair. C and C! â™«The ratio of their frequencies is 2to1. That's the simplest fraction yet!. But get ready. Listen to C and C together. â™«Eeeeuw. A more complex fraction and a terrible sound. The rules of harmony work with more than twonotes. Listen to the chord of C, E and G. â™« Nice, yesé Because this chord has 3 notes,what you're really hearing is 3 pairs of notes at the same time: C and Eâ€¦E and Gâ€¦
And C and Gâ€¦ The ratios of these notes are 5to4â€¦ 6to5â€¦and 3to2. Now brace yourselves. Here's a chord thatsoundsâ€¦pretty gross. â™« Eeesh! To understand why this sounds terrible, let'slook at the fractions. The ratio between C and D is 9to8.The ratio between D and G is 45:32. And the ratio between C and G is 8:5. No wonder it sounds awful to listen to these3 fractions all at once! â™« So far, we've been playing all these notesat once.
But you can also play them separately, too Harmony still works the same way! â™« And even some of the more complicated fractionshave their place, too. In my song quot;Human,quot; I do have a complex fraction snuck in there.See if you can catch it: â™« .did you catch that chordé It was used asa passing chord. But.it was nice, it added some flavour to it.So I hope you learned a little about harmony today why music sounds good, why it doesn'tsound good. And if you want to hear the rest of this song,make sure you visit my channel so you can hear the song quot;Human.quot;
Why You Shouldnt Quit Your Music Lessons
Time for a little honesty, I quit piano lessonswhen I was a kid. And my dad always said I would regret it. Well dad, this me, admittingyou're right. Science has known for a while that learningto play an instrument is good for kids. Kids who take music lessons have higher gradesand graduation rates than their nonmusical peers. Some researchers even claim that itcan boost IQ as well as academic performance. A recent study from researchers at the Universityof Vermont College of Medicine added another reason to the list of why I should not havequit piano lessons. Learning an instrument can help grow the young and changing brain.
The study looked at brain scans of 232 kidsages 618 over a few years to see what playing an instrument would do. The researchers lookedone region in particular, the cortex. This part of the brain changes in thickness askid's brains grow. This recent study found that the more a child practiced an instrumentthe faster their brains organized and the faster their cortical lining thickened. Thesephysical changes in the brain led to important changes in the kids behavior. They were betterat paying attention, managing anxiety, and controlling their emotions and impulses. This isn't the first study to toot the hornof musical training. Previous studies show
that learning an instrument boosts memoryand grades. Researchers from Northwestern University studieda group of kids from The Harmony Project, a music education program in inner city LA.Not only did the participants in the program do better in school, they had higher gradesand graduation rates, but the study showed that kids who play an instrument for two yearscan distinguish the difference in sounds like Pill and Bill better than their nonmusicalpeers which develops important skills like communication and reading. But the benefits aren't just for kids, learningto play an instrument can create neurological
connections that can last a life time. Playingan instrument involves many parts of the brain, visual and auditory regions, motor controland even emotional processing centers are activated. And this leads musicians to havebetter neuroplasticity, which means their brains are better at changing and rewiringthemselves over time and helps when old age brings a decline in cognitive function. Butthese cognitive benefits aren't necessarily unique to musicians, really any kind of specializedtraining can boost the brain in different ways. Now the real question is, does this work forgrown upsé Could learning an instrument later
in life confer the same benefitsé becauseI could seriously use a brain boost. Most research indicates the strongest effects occurwhen learning takes place in childhood. While there's not a lot of research right nowon how learning an instrument later in life affects adult brains, one researcher fromthe University of Zurich says that adults over the age of 65 who pick up an instrumenthad important changes in regions of the brain that control hearing, coordination and memory.Learning any skill at any age helps new neuron growth, so maybe there's some hope for me.
