What is an octave in piano?

Answer 1

If you look at the piano keys you will notice there is a pattern in the way the black notes interleave the white notes. This pattern is repeated several times along the keyboard. If you select any key (black or white) and then look for the same key in the next repeat of the pattern to the right, that is one octave higher. Another way is, for a white note, call that "1", then counting white notes as you go to the right, one octave higher is note 8. Starting with any black note called "1", then counting black notes only, one octave higher is note 6. There are fewer black notes than white ones. One octave higher is double the sound frequency.

Answer 2

The same note played in two places eight keys apart. (Seven, depending on how you count it.) The symbol 8va on sheet music means to play one octave higher.

Answer 3

An octave is a set of eight notes separating two notes, those notes being twice or half of the frequency of vibration. (ex. C d e f g a b C)

Answer 4

An octave means eight consecutive keys. The musical scale is A, B, C, D, E, F, and G. For example, an octave would be the distance between one C key and the next C key.
