Question

For the exercise below, show your work to determine the key. (music!)

Answer 1

Also a shortcut for this is to remember that “the last flat is ‘Fa’” and “the last sharp is ‘Ti’” to find the “last” flat or sharp you simply go to the flat or sharp that is the closest to the right, once you determine where that flat/sharp is, you count up or down to reach do and whatever note that is lands on is the key ( if there is another sharp or flat on that note it would be a flat or sharp key, for example B flat or G major) hopes this kind of helps!

Answer 2

For the third column:

have you ever learned the circle of fifths? (this is for the key) It is the above attachment. You weren't asked to construct it, but drawing it is a good exercise for many music students. The keys on the outside are most important for the work you've been assigned, just match them to the key signature. For example, two flats would be a Bb major, in the major scale, of course. Four sharps would be an E major.

The keys shown on the inside of the circle are the relative minor of the outside ones. For example, C minor has no sharps or flats and its relative minor is A minor.

For the second column:
we can start our work on the closest note to us, example:

I really hope I've helped and explained well!
