Just a quick question I can't find the answer to in reference books. If you have to write a triad in a minor key, do you have to raise the seventh degree a semitone? For example in the key of A minor, if you are asked to write out the triad starting on the dominant (V) would the answer be: E G B or E G# B ? The trouble is I could argue either way In harmonic minor the 7th is raised In melodic minor (up) the 6th and 7th is raised In melodic minor (down, ie natural minor) no notes are raised Thanks to anyone who can help. |

A very interesting question. My answer would be that it depends on what type of triad you are writing. If you are writing a harmonic minor triad then yes, the 7th degree would be raised, so in the key of A minor, chord V would be E-G#-B, but ............ if you are writing a natural minor triad then it would not be raised. It would just be E-G-B.

The questions though will just ask to write a triad.
Since triads are written harmonically I presume the 7th will be raised ? |

Yes, you will need to raise the third in a dominant triad in a minor key for Grade 5 theory.

Is that really the way the question was asked? "The triad starting on the dominant"? Where was this question asked? In the major/minor system that became prevalent since the beginning of the 18th century, the dominant triad in a minor key is still major, so the answer would be a major triad. I wouldn't think of the note to be sharpened as the 7th so much as the 3rd of the triad. |

For the purposes of Grade 5 theory you raise the 7th in chord V.
