Any major scale follows the same pattern. After the first note is a whole step, then another whole step, then a half step, whole step, whole step, whole step, half step; therefore, the fourth note of a scale is two and a half steps away from the first note.
C
A fourth down from "do" (the tonic note in the C major scale) is "fa." In the context of the C major scale, if "do" is C, then the note a fourth down would be F. This relationship is part of the diatonic scale structure, where intervals define the distance between notes.
Yes.
The subdominant in any major scale is the fourth note. So, in C major, the subdominant is the F.
The fifth note of C major scale is G. The fifth note of any scale is always called the dominant.
The third note in a major or minor scale is called a mediant.
Pentatonic
The subdominate refers to the fourth note of the scale ( assuming it is a diatonic scale). In this case the subdominate of the C sharp major scale would be F#.
The subdominant note is the fourth scale degree of any key, for example in C major the subdominant note is F since the scale goes C D E F G A B C.
