In music theory, an interval is the difference between two pitches. An interval may be described as horizontal, linear, or melodic if it refers to successively sounding tones, such as two adjacent pitches in a melody, and vertical or harmonic if it pertains to simultaneously sounding tones, such as in a chord.
An octave is the distance between two musical notes that have the same letter name. If a musician sings or plays a scale (âdo-re-mi-fa-sol-la-ti-doâ) the first and last âdohâ are an octave apart. It is called an âoctaveâ because there are eight notes in a scale (âoctoâ is Latin for âeightâ). If a musician sings or plays the first two notes of the song âSomewhere over the rainbowâ (i.e. the word âSomewhereâ) these two notes are an octave apart.
