26. It's really quite fascinating to realize that the correlation between music & mathematics is literally off the charts.
    I didn't learn how to read music (other than strumming chords on a guitar) until I was almost 50… Or so I thought!!

    I really did try my best… well, actually what I thought was my best, to learn how to play musical notes on the guitar when I was in middle school as well.

    Honestly, I don't know if this is true for everyone but I was super surprised at what it took for me to understand fairly basic all-around music theory. What it took for things to click for me was to 1st apply it on a piano rather than a guitar.

    And to go even one stepfurther, if someone would have told me right off the bat how music theory is so dependant mathematics to the point of being inseperable, I would have looked at it from a completely different perspective.

    BUT in as much as I know this to be soooo completely true/irrefreputable, it's still really hard to wrap my head around the very idea that such a creative artform such as music depends so heavily on something as technical as mathematics.

    I guess that subconsciouly, I always felt like I had to hide one side of my brain or the other because having two dominant sides ofthe brain is an oxymoron 🤷 ✌️💞✌️

27. Dear crash course can you guide how these fantastic animations are designed?

28. You're just TOO FAST, it's hard to cope up with you.

29. I just feel this diagram is talking of amplitude whereas speaker is replacing the word with frequency… Now I'm confused to understand if frequency corresponds to amplitude or amplitude corresponds to frequency or vice versa or they are synonymous in use! Some expert, Help me

30. Ethan at 4:48
