Getting back to F#, it has just occurred to me that the only song I sing in this key is Richard Thompson's "Keep Your Distance".

The way to play this is by using two Shubb capos, one all the way across the second fret, and the other used as a partial capo at the fourth fret, covering the top five strings.

Then you play as if in Drop D.

"Keep Your Distance" is a (very) unusual song inasmuch as the highest note is the VI.

It would be interesting, from a musicological point of view, to do a statistical survey on what the relative frequency of the highest note is in songs.

My guess is that the tonic (I) would be the top note about 75 % of the time, and the dominant (V) would be the top note about 20% of the time, leaving 5 % for the maverick, quirky songs which have one of the other scale notes as the top note.

Maybe this deserves a thread of its own ...
