Finding Your Way Around the Keys: Groups of Two and Three
A standard acoustic piano has 88 keys, which looks daunting at first. In practice the keyboard repeats the same twelve notes from left to right: seven white keys named C, D, E, F, G, A and B, with five black keys tucked between them. What makes the whole thing readable is the black keys, which always sit in groups of two and then three. C is the white key just left of each pair of black keys, and F is the white key just left of each group of three. The distance from one C to the next is called an octave.
The classic first-week habit is counting up from the far left end every time you hunt for a note. It is slow, and it keeps your eyes glued to your hands. The fix is a small drill: close your eyes for a moment, feel for a pair of black keys, then press the white key to their left and say C out loud. Repeat this in every octave, then do the same for F and G. Note-name stickers are fine for a few days, as long as they come off once the names start to stick.
Middle C, the C closest to the centre of the keyboard, deserves special attention from day one. It becomes your anchor for reading music, because it sits exactly between the treble and bass staves on the page. Once you can find middle C in an instant on any instrument, including a 61-key keyboard where it sits slightly off centre, you have a reference point for everything that follows.
You know the keyboard map when you can name any white key from the nearest black-key group without counting from the end.
