Progressively arranged, McGregor's latest pedagogical book for trombone concentrates on helping players increase their technical mastery. All the standard scale forms, major, minor, whole tone, pentatonic, modal and chromatic are covered and the exercises will be excellent for employing the variety of tonguing and articulations the player must use in developing instrumental mastery. This is a great publication for any student of the trombone, no matter what his or her level of proficiency.
