SPOILER!!: How is frequency measured

How is frequency measured? Um.... She raised her hand and guessed, "Well...frequency makes it sound like a counting thing, how many times something happens....but I don't know a specific measurement for sound." But as soon as she heard what some of the other students said, she knew she'd heard that hertz word before somewhere. But no matter, they'd be learning more about it now and maybe she'd remember next time.

SPOILER!!: Which pitch is higher

Well this one seemed pretty easy, because she had just explained it. Like, literally JUST. So, that must mean she had explained it well, because Eliza felt like she understood immediately. She raised her hand and agreed, "The three ten would be higher, because the number is higher and has more waves per second, like you said." She was happy to be understanding some new things in this lesson.

Okay, scratch that. Now she was confused. What does that mean exactly? She wasn't sure where to start or what she was really looking for...so she agreed with some other students and tried to feel like she understood. "Um, well yeah I agree that if you started with a note at 310 hertz, then a note at a 2:1 ratio higher than that one...would be 620 hertz. Right?" She thought that sort of made sense.

But enough of artwork. "And technically, there are little squares on an ice cream cone." Beam. See! The treat WAS related! "Enough about art though, we'll be moving on to another topic, which is similar to art in a sense." She paused a moment, as she prolonged telling them of the next topic in today's lesson. "Music. Math, or arithmatics, can be used to create music. Sound is a travelling wave, which oscillates through matter. An important term in music is called frequency; what is it measured in and what does it mean?" How is frequency measured? Um.... She raised her hand and guessed, "Well...frequency makes it sound like a counting thing, how many times something happens....but I don't know a specific measurement for sound."

SPOILER!!: Which pitch is higher Quote: Originally Posted by PhoenixRising "Yes, as most of you seemed to guess or knew, frequency is measured in a unit called hertz. When a string is plucked on a musical instrument, it generates back and forth vibrating waves. The number of times per second that these waves hits our ears is called frequency." Hadley explained, even though some of them seemed to have a greater understanding of music than probably herself even. She mostly knew the theory. "So the more waves per second, the higher the pitch, the fewer the waves produces a lower pitch." "Chords and harmonics are created with the right numbers at the right musical frequencies. So ultimately it all comes down to where the string is plucked and on the vibratory nature of the frequency waves on if its going to sound good or bad. It depends on ratios between notes, as well. Many ratios exist in relation to musical notes, which enable us to produce harmony in music. And thus, more appealing sounds." "So let's continue on with exercises to help you understand pitch first. Which of the following produce high pitches?" "130 Hz or 310 Hz?" Well this one seemed pretty easy, because she had just explained it. Like, literally JUST.
