Watch the Phrygian Major online guitar lesson by Chris Buono from Modes That Matter
In this lone example set to a modern Klezmer vibe the Phrygian Dominant mode sounds most at home. Of course, that is also due in part to the uniquely idiosyncratic phrasing this style possesses. Here you should make a conscious effort to exploit the two half steps--1-b2 and 5-b6--especially with trills. Once again the Phrygian Major mode can be played horizontally across the 8 bar loop that’s made up of four chords, all of which are diatonic to the mode. In doing so just stay weary of what change you’re playing over and use your ears to ensure you’re playing the right notes over each chord.
Throughout this style setting and the surf setting you may find it worthwhile to map out each string as a single string scale to play over the jam tracks. To do that you’ll need to know the notes of the scale, which in this case is: B C D# E F# G A. Next, on each string look for which one of those notes can be played at the lowest point of each string. It’s either going to an open string or on the 1st fret. From there you just continue on up the scale mapping out the note locations. You could identify the lowest notes by their scale degrees and then build the rest by degree. If you can pull that off it shows you’re really getting a handle on the degree approach, which is a very powerful tool that will allow you to transpose on the drop of a dime.
