Question

Okay in music there is four half steps that never change in the major scale. What are they?

Answer 1

b-c and e-f

Answer 2

Also, there are many kinds of scales. For example in a minor scale (take A minor e.g.) the structure is such that the half steps are situated between the second and third note (B+C) and between the fifth and sixth note (E+F).

Different scales, and or modes mean different step patterns and thus the placement of these half steps will vary...

Also, the Harmonic minor will see a raised sixth note (F#) altering the step pattern and shifting the semitone from to between the sixth and seventh. In addition the Melodic minor raises the seventh note (G#) shifting the semitone to between the seventh and eighth...

Answer 3

Actually, if you are talking about the arcitechture of the major scale as we know it in Western music, there are 2 half steps or semitones. The first is between the 3rd and 4th tones of the scale, and the second is between the 7th and 8th tones of the scale (the 8th tone is where the tonic repeats an octave higher). The sequence of whole tones and semitones from bottom to top is "whole-whole-half-whole-whole-whole-half... You can construct a major scale starting on any tone in the chromatic scale using these guidelines, and you will always build a major scale.
