B major's submediant note is g#
In the perspective of European-descendent theory, the degrees of any key or scale (major, minor, or modal) can be classified as follows: 1 - Tonic 2 - Supertonic 3 - Mediant 4 - Subdominant 5 - Dominant 6 - Submediant 7 - Leading Tone Let us take the case of C major as our key/scale: C - Tonic D - Supertonic E - Mediant F - Subdominant G - Dominant A - Submediant B - Leading Tone Similarily, this works in the minor keys, too. Using A natural harmonic as our key/scale: A - Tonic B - Supertonic C - Mediant D - Subdominant E - Dominant F - Submediant G - Leading Tone
The dominant note is the 5th note in the scale. In the B Major scale, F is the dominant note.
The leading note of B major is A#.
The subdominant in a scale is the 4th, which in the key of B-flat major is E-flat.
Eb Major

The submediant, the sixth degree of the G major scale, is E.E natural
The submediant - which is the note a relative minor scale begins on

The submediant is lowered (E to Eb)The mediant is lowered (A to Ab)The leading note is lowered (B to Bb)
Submediant
In the perspective of European-descendent theory, the degrees of any key or scale (major, minor, or modal) can be classified as follows: 1 - Tonic 2 - Supertonic 3 - Mediant 4 - Subdominant 5 - Dominant 6 - Submediant 7 - Leading Tone Let us take the case of C major as our key/scale: C - Tonic D - Supertonic E - Mediant F - Subdominant G - Dominant A - Submediant B - Leading Tone Similarily, this works in the minor keys, too. Using A natural harmonic as our key/scale: A - Tonic B - Supertonic C - Mediant D - Subdominant E - Dominant F - Submediant G - Leading Tone
In ascending order, the names for each scale degree are the tonic, supertonic, mediant, subdominant, dominant, submediant, leading tone, and the tonic again.
E
A or VI or 6
The dominant is the 5th tone in the scale. In a D Major scale, the dominant is A.
The dominant note is the 5th note in the scale. In the B Major scale, F is the dominant note.
