Fundamentals of music theory
Music theory is based on just one concept: the musical interval. This is the term used to describe the relationship between different notes in the scale. The distance or spacing between different pitches is termed an interval. In western music, the smallest possible interval is a semitone. This describes the distance between two consecutive notes on the piano keyboard. The interval patterns for major and minor provide a series of pleasing intervals between the different notes or pitches in the chosen scale. While the natural minor scale can provide pleasing intervals between notes, many musicians consider them to sound disjointed or displaced when composing harmonies and melodies. The major and minor interval patterns are by far the most popular two modes of music. In almost all instances, electronic music producers will employ either the Ionian or the Aeolian interval patterns.
