Jack Campin has page on it, and he mentions mixolydian:
The mixolydian mode is important, because it derives from the Middle Ages, and
persisted in Western music on a parallel track on the development of the CPP
(Common Practise Period) major/minor tonality. Cf.
So as for the GHB tuning, I think it would be good to call it A mixolydian,
since A is the tuning note, and because it indicates that Scottish music isn't
As for the notation, A mixolydian has the same notes as D major, but is a
different mode: different notes being important. Most notably, A mixolydian
mode has a finalis, or finishing note at A. The D major has a tonic at D, which
might act as a finalis, but need not be: it is enforced by a D major chord.
(For example, Kurt Weill's "Mack the Knife" might be finished with a C major
chord, but its final note is an A.)
So if a GHB tune ends with the note A, then it is in A mixolydian, but the
omitted key signature will be the same as that of the D major scale, because
they have the same notes. In the historical past, the use of key signatures
have been more arbitrary, so it in itself need not indicate anything about what
mode the music is in.
So let's try to extract correct formulation from this long explanation:
GHB music is typically written without a key signature, using the A mixolydian
notes it has, which are same same as that of the D major scale. So if a key
signature is written out, it will be the same as those scales: C# and F#.
