In most cases, the keys on a piano are almost always eighty-eight. Fifty-two are white and thirty-six black. The arrangement of the keys is seven octaves plus two initial notes (a third interval, from B to first C).

In practice, starting from the left, the white keys indicate the seven notes. These are: la, si, do, re, mi, fa, and sol. The major scale follows this series six times. Finally, the final C ends the keyboard.

The black keys are alterations, that is, the flats or sharps, and produce a higher or lower sound by half a tone compared to the neighboring white keys.

Electrical notes

Some piano models, the grand piano, for example, add nine more keys. These lie on the bass side. That is, on the left. Thus, this extra set generates the eight complete octave.

On the other hand, electronic keyboards may also have fewer keys than acoustic pianos. For example, there are 76-key electronic pianos and 61-key keyboards (five octaves), or even 49-key keyboards (four octaves).

The piano keyboard

The seven notes, that we now know, form a block called an octave. The keys on a piano repeat this series within the keyboard several times.

Each octave generates a different pitch. The octaves on the left of the piano are the lowest notes and the octaves on the right are the highest.

This could be confusing because you might be wondering how the first C (or DO) differs from the others. And why don't they continue with the letters or names?

For pure usability, the 7-note tonal system has established itself over time. Classical musicians found it to be the most straightforward form of writing music. The octaves repeat upwards or downwards in blocks of seven as a simple convention.

Each note also represents a specific Hertz frequency. So, a low C note will generate a Hertz amount, which is different than a higher C note produces. Therefore, both notes, although called C, are distinctive sounds.
