Say I have to play from C to C by pressing every key,not a glissando. How do I practice doing this? I think I've seen sheets where there are parts that go from C to B(of the other octave). If they were longer notes I think I could manage to adjust my hand in time. But how do I play this properly when it's rather short notes. 8ths or 16ths.Actually I'd have problems with 4ths aswell if the song is fast.
Sorry if I'm explaining this badly.I don't have much knowledge of music. Here's an image of something that I can find thats in a way related.
Here's one image. But I would also like to know how to play when there aren't any notes that play twice in row,like that C C or when all the keys are one after another like CDEFGABCDEFGAB quickly.
Thank you.
