 So how do you make these scales visually easy to remember so that you don't always need a piano to rely on? Use piano worms. So if you take F sharp major, it's a very distinct black-to-white note combo. B major, it's like a small boat and a big boat turned upside down. And then D flat major, one of my favorite scales. It's a good way to remember your scales. So I wouldn't say that these three black note scales are tricky because it just looks tricky in staff notation because they give you those huge list of sharps and flats that you have to remember while you read. But in the real world, it has a lot of grip. The grip factor is nice and it doesn't slip like a C major scale, which is so easy to fly around and play the wrong notes.
