Notes that have different names but sound the same are called enharmonic notes.

You can also name and write the F natural as “E sharp” F natural is the note that is a half step higher than E natural, which is the definition of E sharp. For example, the G sharp and the A flat are played on the same key on the keyboard they sound the same. Notice that, using flats and sharps, any pitch can be given more than one note name. When they are a whole step apart, the note in between them can only be named using a flat or a sharp. Some of the natural notes are only one half step apart, but most of them are a whole step apart. A flat sign means “the note that is one half step lower than the natural note”. They appear in the key signature, or right in front of the note that they change.Ī sharp sign means “the note that is one half step higher than the natural note”. How do you name the other five notes (on a keyboard, the black keys)? The natural notes name the white keys on a keyboard.īut in Western music there are twelve notes in each octave that are in common use. (When you get to the eighth natural note, you start the next octave on another A.) These seven letters name all the natural notes (on a keyboard, that’s all the white keys) within one octave.

Instead, they just give the different pitches different letter names: A, B, C, D, E, F, and G. But musicians usually don’t want to talk about wavelengths and frequencies. The higher the frequency of a sound wave, and the shorter its wavelength, the higher its pitch sounds. Pitch depends on the frequency of the fundamental sound wave of the note. The pitch of a note is how high or low it sounds.
