Lesson 3 Key —Hold the key of tracks! Major and Minor—


  • Minor scale


The tone series with intarval “whole-half-whole-whole-half-whole-whole” is called “Natural minor scale”. In tonic solfa, it is 1-2-♭3-4-5-♭6-♭7. (It’s called with “Natural” because there are three kinds of minor scale.)

Major scale (1234567) has the tones composing major chord (135). Natural minor scale (1,2,♭3,4,5,♭6,♭7) has the tones composing minor chord (1,♭3,5).

For your infomation, major scale and natural minor scale have the relationship as two sides.


See, an example.


When starting 6th of major scale, it becomes natural minor scale. When starting ♭3rd of natural minor scale, it becomes major scale.

  • Key

Key is the most basic tone (or chord) in a track. For example, F tone is basic in F(F major) key, and Gm chord is basic in Gm(G minor) key.

We can decide key, seeing ♭ or ♯ written at first area of music score.


Like this. It’s OK to remember the above two, often played. And B♭ or Gm (having two ♭), E♭ or Cm (having three ♭) are also often played.

We decide major or minor from the brightness of the track or the last chord.

  • Points

Major and Minor, seems like day face and night face

Let’s remember natural minor scale.
