The home tone of the key of C major is the note C. This is the tonic note, which serves as the central pitch around which the other notes of the scale revolve. In the context of harmony and melody, the C major chord (C-E-G) is often used to establish a sense of resolution and stability within the key.
The leading tone in a scale is one half-step below the tonic. In the key of C# major, the leading tone is B#.
The leading tone in any key is one half-step below the tonic. In the key of D-sharp, the leading tone is C-double-sharp (it can't be spelled as D-natural, because the letter D is already used for the tonic).
That would be the key of A-sharp minor, the relative to C-sharp major, which contains seven sharps. The leading tone is G-double-sharp.
Tone Tone Semitone Tone Tone Tone Semitone, is always the gap between notes in any major scale, which is why most scales need sharps or flats. For example, C major is: C - up a tone - D - up a tone - E - up a semitone - F - up a tone - G - up a tone - A - up a tone - B - up a semitone - C.
Tone and semitone are two words to describe differences in pitch between two notes. A semitone is the difference between F and F#, that is, only a bit. A tone is the difference between F and G, twice as much as a semitone.
If you mean the same key-note, the simple answer is 'no'. A home tone is the note a particular scale starts on; for example - in the Ab major scale, Ab is the keynote and in the key of D major the key-note is D. The only common scales with C as a home tone are C major, C minor harmonic, C minor melodic, C minor (natural), C blues scale etc.
C is the leading tone in the Key of D.
The leading tone in a scale is one half-step below the tonic. In the key of C# major, the leading tone is B#.
The leading tone in the key of D, whether major or minor, is C#.
The syllable is Re. D is the second tone up from the tonic note, which is C (and do), so it is Re.
The leading tone in any key is one half-step below the tonic. In the key of D-sharp, the leading tone is C-double-sharp (it can't be spelled as D-natural, because the letter D is already used for the tonic).
Tone deaf
The full tone modulation from B♭ moves up a whole step to C. This means that if you start in the key of B♭ major, you would transition to C major after the modulation. Similarly, if you were in B♭ minor, you would move to C minor. This modulation can create a bright and uplifting effect in music.
That would be the key of A-sharp minor, the relative to C-sharp major, which contains seven sharps. The leading tone is G-double-sharp.
