Why are there only 5 black piano keys per octave?
Most people are familiar with the appearance of piano keys; alternately spreading white and black keys across keyboards. Have you ever seen that there are fewer black piano keys than white piano keys? To understand the pattern of black keys on a piano, it is important to be familiar with notes and their sharp and flat tones .
Piano Keys
The white keys on a piano are notes that are in their natural state. That is, the pitch unchanged, such as C or A . When a note is raised half a step by adding a sharp or flat coincidence, the key that often corresponds to the accidental is a black key, half a step away from the adjacent white key. Each note on the piano can have a sharp or flat tone, but there are fewer black piano keys than white. This means that not every sharp or flat note is played on a black key. Some sharp objects, such as B ♯ are played on a white key because C (B ♯) is half a step higher than B.
