A musical scale is a sequence of tones arranged in whole tones, semitones and other intervals. The basic scale is the C major scale, which is played on the piano using all white keys. Scales are divided into "major scale" and "minor scale", that is, "major mode" and "minor mode". The major scale consists of 7 tones, of which there are semitone intervals between the 3rd and 4th tones and the 7th and 8th tones, and there are whole intervals between the other tones. There are semitone intervals between the 2nd and 3rd notes and between the 5th and 6th notes of the minor scale.
