Thought about it and totally forgot to add it to my message just before posting...HinagikuKatsura wrote:
If you're bored or waiting for someone, and there's a table next to you, what will you do?
On your left hand (this applies also to your right) , try tapping your little ring finger first, then the middle one, and lastly your index finger. If you're left handed (just like me), try adding your thumb on the sequence; otherwise, add it on your right. Try slowing it down until you find the appropriate beat for the stairs.
Practice that
Well, it's just as Hinagiku said. I also use this method to practice some little tricky patterns when played quickly such as 13-2-13-2 or 1-2-1-3-1-2.
