A metal shred won’t sound nice at a kid’s party – however good you play it.
Stairway to heaven will never impress a pro guitarist.
And if you play your favorite Kirk Hammett solo to your wife, it will only leave her with a weird face asking “oh, that’s it? Is this what you’ve been practicing for so long?”
When you’re asked to play something, it’s your job as a guitarist
to play a song based on the mood and context that your audience are in.
And when you’re in the spotlight. It’s hard to choose a perfect song for the moment.
That’s why the course teaches you 5 songs for different mood and settings. And show you when to play which.
