An octave is the interval between one musical pitch and another pitch that is either double or half its frequency. In simple terms, it is the distance between two notes with the same name but at different pitches. For example, if you play a C note, the next C note higher or lower is an octave away. The sound of these notes is perceived as very similar, though one is higher or lower than the other. Octaves are fundamental in music for creating harmony and structure, and they help in organizing the musical scale.

Octavo is a book size where each page measures approximately 6 inches by 9 inches, or 150 mm by 230 mm. It is created by folding a standard sheet of paper three times, resulting in eight sections that together make sixteen pages. This method produces a compact and practical book format, commonly used for various types of books, including novels, biographies, and academic texts. It provides a good balance between readability and portability.
