That’s a creative idea for beginners and amateurs, i’ll keep this in my mind, thanks for sharing!

Nice trick, thanks for sharing. Here is something similar from “Pensado’s Place”:

and
Into The Lair #58 – Ear Training Part 2
Dave Pensado’s video is a MUST!!! The guy is one of the most humbled mixing engineer who is also REALLY good at what he is doing.
Great links, thanks!

Thank you for the links!
As I just started making music, I have gotten no idea about what to do. I find the links very helpful.
