SCALE

An ordered set of pitches inside an octave. Major, natural minor and the modes are the sets most pop, rap and dance music is built from.

Key takeaways

  • An ordered set of pitches inside an octave.
  • Major, natural minor and the modes are the sets most pop, rap and dance music is built from.
  • Most Western popular music runs on the major scale, natural minor, and the modes derived from them, with the pentatonic and blues scales covering an enormous share of riff and vocal writing.
  • Set your DAW's scale highlighting to D minor before writing a bassline and every 'wrong' key on the piano roll greys out.
  • Watch out: assuming a scale dictates a mood.

Quick checklist

  • Can you define scale in one sentence without looking?
  • Can you point at scale in a real session, mix or contract?
  • Have you tried the practical move above at least once?
  • Would you catch the common mistake before it costs you a take?
  • Have you opened one of the primary sources below rather than a forum thread?

SCALE IN DEPTH

A scale is a filter: it tells you which of the twelve available pitches belong to a piece and which will read as outside colour. Most Western popular music runs on the major scale, natural minor, and the modes derived from them, with the pentatonic and blues scales covering an enormous share of riff and vocal writing.

How it works in practice

Set your DAW's scale highlighting to D minor before writing a bassline and every 'wrong' key on the piano roll greys out.

The mistake people make

Assuming a scale dictates a mood. The same set of notes reads as sad or triumphant depending on which pitch you treat as home and where the chords resolve.

WHERE SCALE SITS

Scale belongs to music theory basics in the Sampled music glossary. The vocabulary you need before anyone can explain a chart, a chord chart, or a session to you.

TERMS THAT DEPEND ON SCALE

  • Interval

    The distance between two pitches, counted in scale steps (a third, a fifth) or in semitones (4, 7).

  • Key and key signature

    The home pitch a piece gravitates to, plus the sharps or flats written at the start of the staff that spell out its scale.

  • Semitone and whole tone

    The semitone is the smallest step in Western equal temperament; two semitones make a whole tone. Everything from scales to chord spelling is counted in them.

  • LUFS

    Loudness Units relative to Full Scale — the perceptual loudness measure streaming platforms normalise with, defined in ITU-R BS.1770.

  • Blanket licence

    One licence covering a whole repertoire rather than a song at a time. It is how radio, venues and streaming services clear performances at scale.
