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.
