The easiest method to memorize notes on a piano is to sign each key of the keyboard marker. However, there is another method that is often used in music schools for memorizing the notes. Take a rectangular piece of cardboard or dense landscape sheet of the desired size and draw on it the keys within one octave (you can add a few keys left and right). Completely paint the entire piano keyboard is hardly appropriate, since the location of the keys in octaves is repeated.
Sign next on your drawing the names of the notes corresponding to the keys. First, you can do without sharps or flats, and when you master the notes, then you can begin to them. It remains to put the picture of the keyboard with notes on the stand for music and start memorizing. Press any key and speak the note aloud, then verified with the image.
By the way, you can memorize the notes even if a piano or synth no. Drawing or printed image of the keyboard, signing only note - for example, "to". It will be a point of reference if you get confused. The main thing is to remember the order of seven notes. Now you can just the image to "push" a note to talk to her.
