What are keys and octaves?

A full piano keyboard consists of 88 keys spanning seven octaves plus a minor third. While every pitch will sound different, the notes repeat in a series ranging from A-G. The distance between a note and the next time that note repeats on the keyboard is called an octave. So, for example, C-C is an octave.
