Octave (piano terms)
Here's another musical term for all you wannabe piano nerds out there.
Btw, you can learn any song you want within 4 days. But, you have to WANT it. If piano's "just a hobby", it's not gonna happen. Come on, where's your childlike wonder? Don't you want to make some magic?
Stop avoiding your true nature.
You don't have to dedicate your whole life to it. Just 4 days.
This is your chance. No more excuses.
