How long did it take you to getgud?

I’m new only played this two days I feel like I’m making some progress, but I feel like I’m a slow learner because I’m musically inept. I’m getting 100% sometimes, mostly higher end of the 90%’s on a few easy songs got a 92% when I tried a medium track. I feel like when the blue button is involved I panic same with the orange lol.

Should you be on medium from the get go or is it normal to start on easy. I feel like easy might be meant for kids and I should be on something more advanced already?
