In the key of C major, the chords in the progression I-vi-ii-V are as follows:
- I (C major): C - E - G
- vi (A minor): A - C - E
- ii (D minor): D - F - A
- V (G major): G - B - D
To determine which chord begins at the highest position on the staff, we should look at the root position of each chord and their lowest notes:
- I (C major): Bottom note is C.
- vi (A minor): Bottom note is A.
- ii (D minor): Bottom note is D.
- V (G major): Bottom note is G.
Now we can visualize the bottom notes of each chord:
- C (I) is lower than A (vi)
- A (vi) is lower than D (ii)
- D (ii) is lower than G (V)
Thus, the lowest note of the I chord is C and the lowest note of the V chord is G.
Since G is the highest note among the starting notes of the chords in root position, the chord that begins at the highest position on the staff is the V chord (G major).
So the answer to the question is:
V.
