harmonization of given melodies with modulation

• foreign accidentals to the key that we are in will indicate a modulation
• the accidental should prove, normally, to be a member of a dominant 7th chord
  • the accidental, depending on chord formulation, must show that it goes to it’s proper resolution in the proceeding note of the melody
• this is also an issue of judging the distance of the key we are going from, to the key that we are going to
• for the purpose of this book we will not be doing remote key modulation
• example
  • melody = C major
  • accidental = C#
  • possible keys to modulate to = D,d,b
    • D,d = V7/ii(II)
    • b = vii°7/vii
• the melody will normally tell us where we need to go, out of the three normal modulatory options that we will have available to us
• sometimes a singular note in the melody with NO accidental will still give us the indication to modulate
• rare cases can even occur where we modulate when the melody does not indicate such
