i don't take classes so i don't know much about piano like what a sixteenth note is or what exactly scales are, but i can play hard songs. so if u are gonna tell me how please simplify it as much as u can…good luck and thanks
okay rhythm wise, let me give you a quick lesson:
a 16th note is a musical note having the time value of a sixteenth of a whole note. In other words, it takes 4 sixteenth notes to equal a quarter note.
many musicians will find that playing slow is just as hard (if not harder) than playing fast, so my advice to you is to buy a metronome, and try your best to stay in rhythm with the metronome. in addition, i think you should take some classes at least for a little while so you can learn these basics. I don't know what you classify as "hard," but as long as you know which rhythms go with which notes, you'll be fine. if you can't afford a metronome, have a family member clap an even beat for you and try to stay with it.
another way you could learn to play slower is play extremely slow. I'm talking a note every 3 seconds. but make sure you keep your rhythm. keeping your rhythm will prevent you from rushing. you don't want to get in the habit of rushing. good luck!
