There's a LOT you can do with scale shapes besides just going up and down one note at a time.
Most of the music you listen to can fit into scale shapes. Knowing your scales can allow you tons of musical ideas.
Turns out that John Petrucci and I use scale shapes in a similar way to create riffs.
Check out this video where Petrucci demonstrates this approach to song/riff writing:
John Petrucci is a beast on guitar. He is also one of the few super shredders who can ACTUALLY TEACH.
In a Guitar World lesson, John shows two "shred runs" that look like the opposite of how it sounds.
What the heck does that mean?
It means the notes ascend when his hand descends.
