Phrygian and m7b9 chord ?

[liskou]

do you mean 7b9sus?
(it has the minor 3rd in the scale and typically associated with Phrygian)

it's not exactly the same as you omit the third and use the fourth instead of having the regular 1 b3 5 b7 b9 (if I'm not wrong ) but you're right, I can use 7b9sus to practice phrygian.
Thanks

Hello Etienne
my reference for the b3 was as part of the scale, but yes the voicing for the chord would have the sus 4.
