The Freygish mode comes from a different scale system than the other modes.
It is actually a mode of the harmonic minor scale and is used in Jewish Klezmer
music. It is the same as the Phrygian mode, with a major third instead
of a minor third.
The Freygish and Phrygian modes in the key of D are very
useful scale patterns to know in DADGAD. The fingerings are the exactly the same
as the G Harmonic minor scale and the G natural minor scale respectively.
Knowing these patterns opens up very interesting G minor possibilities. In
DADGAD the chords of the G minor scale are quite accessible, such as D#, F and
Bb.
