The song of the week is 'Are You Missing Me' in the key of G.
Jim & Jesse - key of G
The progression for the verses and breaks is:
The progression for the chorus is the same as that for My Home's Across The Blue Ridge Mountains, and the verses of How Mountain Girls Can Love and Columbus Stockade Blues:
Notice that the verse and chorus progressions differ from each other only by two measures. For helping to get the song off to a strong start at the jam, the main thing to remember about the verse progression is that there is a change to the 4 chord in the second measure of lines 1 and 3.
Melody & Harmony
The melody for the chorus has little in common with the melody for the verse, and is not nearly as straightforward as the melody for the verse. Each line of the chorus starts with a different melody note (disregarding the nonessential grace notes that the first and third line begin with). The melody for lines 1 and 3, which one might expect to be similar, are significantly different from each other, and line 4 begins with a uncommon starting note for a line, the 7th note of the major scale (F# note when in the key of G).
On the recording, the harmony part is prominent in the mix, and in certain spots, most notably the beginnings of lines 2 and 4, the harmony notes form wide intervals with the melody notes (a major 6th for the beginning of line 2 on the word 'with': the notes are separated from each other by 9 half steps: A is the melody note, and the F# above it is the harmony note; a minor 6th for the beginning of line 4 on the word 'are': the notes are separated from each other by 8 half steps: F# is the melody note, and the D above it is the harmony note).
For all these reasons and more, it is very easy to misidentify many of the melody notes for the chorus. So, in addition to the melody sheets for the verse which are intended to give people a good starting point for coming up with melody-based breaks on their instruments, I have also included in the attachments a chorus melody and harmony sheet for the benefit of singers which is based upon the first chorus on the recording. The lower of the two parts shown on the sheet is the melody, and the higher of the two parts is the harmony. Special thanks to Kathy Allyn and to my wife Renee for their time and assistance in helping me to produce a much more accurate transcription than what I could have done on my own.
