I am harmonizing a melody and that ^1 in m. 2 is supposed to be harmonized with a chord other than a tonic so I figured it must be a vi chord. The ^1 ^2 ^3 in the soprano usually works well with vi V I but I cant make it work somehow. If I want V on the second chord of m. 2 I will get two large leaps in the tenor and alto. I cant go lower because I have to use keyboard style and an octave is the limit. Can anyone recommend a different harmony using only the diatonic chords?
Here is the initial exercise
