According to Tamingthesaxophone.com, these include the dorian bebop, which is a Dorian scale with an added major third degree; Mixolydian bebop, a Mixolydian scale with an added major seventh; and the major bebop, which is a major scale with an added b6 degree. Dorian bebop scales match with minor seventh chords, Mixolydian scales match with dominant seventh chords and major bebop scales match with major seventh chords.
Practice playing each scale in a different key. Run the scales starting from a different root note to familiarize yourself with the pattern of each.
Play the scales in rhythm. Learn to play the scales in eighth notes with a swing rhythm, which is common to jazz music. This will make it easier to play the scales in actual songs.
Practice mixing the scale types. Since a typical jazz song will use many different chords, use each scale in succession. Try playing one after the other smoothly.
