Glenn--Miserlou is absolutely and positively major in the Western sense, because it has a major third in the scale. In western music, this is sometimes called the Double Harmonic Major Scale, owing to the fact that it has two 1 1/2 step intervals, one between the 2nd and 3rd and the other between the 6th and 7th, in the fashion of the Harmonic Minor Scale.

In Arabic music, this is called Maqam Hijaz Kar.

In Arabic music, the scales are called Maqam, and though of as two consecutive trichords, each of which has a name. Hijaz being the name of the trichord that consists of 1/2 step-1 1/2 step-1/2 step-Hijaz Kar consists of two Hijaz trichords, on that starts on C, the other that starts on G.

All of the notes in all three parts of Miserlou occur in two major chords--
in the key of C, those two chords would be C {C-E-G} and Db7 {Db-F-Ab-Cb(B)}.

So GUEST this means that you can play the song using just those two *major* chords. You'll sound just like Dick Dale. No minor chords needed, or even wanted.

That said, I am inclined to play the third part of the melody:(still in C):

||FF/FF/EbEb/EbEb/DbDb/DbDb/CC/CC/
DbDb/CC/CC/DbDb/DBDb/CC/CC||

Jack Campin knows a lot about modes and maqams, and such things(way more than me), but this is probably TMI already;-)
