These three licks demonstrate some of the sounds available in the Phrygian mode. The Phrygian mode is commonly played over minor or minor seventh chords. Once you are comfortable with these licks, try playing them against the Phrygian jam along progression on page 202 (CD2 Track 49).
Every mode has its own characteristic sound. Listen to the Spanish Flamenco sound produced by the E Phrygian mode in the following example. Jazz trumpeter Miles Davis makes extensive use of this and other modes on his album "Sketches of Spain" Another Miles Davis album which is essential for all aspiring Jazz players is "Kind of Blue" which features John Coltrane on tenor sax and Julian "Cannonball" Adderley on alto sax. Most songs on this album are modal, and feature great improvising by all the musicians. The phrygian mode is also frequently used by Fusion and Metal guitarists e.g. Al Dimeola and Joe Satriani.
