Realiza una escala ascendente y descendente en do mayor utilizando negras corchetas en compas 2/4​

the first thing you will need is patience a simple drawing can take 2 years the more time the better, you will start by copying some drawings and when you get better at it you can start doing your own drawings. when your drawing you need to be super patient. even proffessionals learn new things all the time. i hope this advice .
