Music scales: major, minor, pentatonic, blues and the modes

A scale is a set of notes in order of pitch, defined by the pattern of whole steps and half steps between them. Change the pattern, and you change the color of the music. In this guide, we'll go through the scales you'll actually meet, one family at a time, each with its pattern and its sound.

The major scale: whole, whole, half, whole, whole, whole, half

The half steps fall between degrees 3 and 4, and between degrees 7 and 8. That pattern, the same in every key, is what makes a scale sound major. You'll find all fifteen major scales in the major scale guide.

The three minor scales

  • Natural minor goes whole, half, whole, whole, half, whole, whole. A minor uses only the white keys, from A to A.
  • In harmonic minor, the 7th degree is raised a half step. This creates a leading tone, and a step and a half between degrees 6 and 7.
  • In melodic minor, degrees 6 and 7 are raised going up, and in classical practice they're lowered again coming down.

Pentatonic and blues scales

The major pentatonic keeps five notes of the major scale and drops the 4th and the 7th, the two notes that form half steps. On C, that leaves C, D, E, G, A. With no half steps, almost any order of its notes sounds consonant, which is why you hear it everywhere, from folk songs to rock solos. The minor pentatonic uses the same notes, starting from A. Add one note, the flatted fifth, and you get the blues scale.

The chromatic scale

The chromatic scale uses all twelve notes of the octave, one half step apart. It has no home note of its own, so composers use it for color, for runs and for passing notes.

The seven modes

Now play only the white keys, but start on a different note each time, and you get the seven modes. Each one keeps the same notes but moves the half steps, so each has its own character. Dorian is the minor mode of much funk and jazz, and Mixolydian is the major mode with a flat seventh that you hear in rock and folk.

What is the pattern of a major scale?

What is the difference between the pentatonic and the blues scale?
