Interval

  1. The difference between one note and an adjacent note in a scale.
  2. The difference between any two notes in a scale.

Intervals are very important in music and each interval produces a pleasant sound (concordant) or an unpleasant sound (discordant).

Intervals are the basis for chords and harmony. If a discord occurs, it is usually as a way of introducing tension into the music and begging for a resolution to a concordant sound. A typical example of this is the chord ending of a 7th -> Tonic e.g. G7 to C. This is also called a cadence.

 An interval, or musical interval is the difference between two notes. The smallest interval in western music is a Semitone. An interval of 2 semitones is a Whole Tone and 12 semitones is an Octave.

Some intervals are more important than others, like the Octave. They form the basis of Melody, Harmony and Chords.

Intervals are more conveniently thought of in the Key, Scale or Mode in which music is played. There are 8 'Degrees of Scale' (the proper term for the actual notes played in a scale) making up a particular Scale or Mode.

e.g.

| Scale in the key of D Major - | **D** | **E** | **F#** | **G** | **A** | **B** | **C#** | **D** |

The Major Scale is made up of 8 degrees and 7 intervals.
