Trombone Book Three of the Brass in Color Beginner Method Series uses a color-coded tablature (Color Slide Positions) to help students learn the slide positions of the trombone and apply them to notes in the High Range.
 
The High Range begins with the notes Gb/F# notated on the staff, and the remaining notes of the High Range are  presented in an ascending chromatic order and end with the notes Bb/A# that are notated above and at the top of the staff.  Along with the notes of the High Range the notes of the Middle Range are also presented in an ascending order to help students learn the correct slide positions for the High Range.
 
While learning the notes of the High Range students will be introduced to the music concepts of playing in 3/4 time, dotted quarter notes and the harmonic minor scale.  Additionally, etudes are included to complete this trombone instructional series.  These etudes allow students to practice playing each pitch of the Low, Middle and High Ranges without using Color Slide Positions.  
 
Standard music notation has also been included with each lesson.  Breath marks, articulation, dynamics and tempi are not noted in the lessons and may be added by the instructor as needed.  Also, key signatures are not used so that students will focus primarily on listening and learning the slide positions associated with the notes.
