In Western music, the octave is divided into 12 equal intervals, known as semitones. These semitones are represented by the white and black keys on a piano keyboard. Each semitone represents a difference of one half-step in pitch.
Octave is a high-level programming language primarily used for numerical computations and data analysis. It is an open-source alternative to MATLAB (Matrix Laboratory) and is designed for numerical linear algebra. Octave provides a command-line interface for solving linear and nonlinear problems numerically, and it supports various data types, including matrices, vectors, and arrays.
