The final book in the Harp Olympics Series, Stage IV, includes more technical studies than the previous volumes and the student should expect to stay with this book a little longer than the others. In Stage IV, the student studies advanced four-finger arpeggios and chords, directional placing, trills, glissandi and scales, harmonics, and etouffes. In the Games and Drills section, students study complex key signatures, chords, scales, and rhythms. Stage IV also includes a lesson in pedal technique with practice pieces. The Solos section includes some pieces requiring pedals, which are not suitable for lever harp.

As with all of the Harp Olympics books, qualifying Marathons at the end of each book will serve as a review of the material covered and be an incentive for the student to progress to the following stage. A special certificate is included, signifying a certain level of accomplishment, to be given to the student upon completion of each book.

"At the completion of Stage IV, the student will be at the level of the many fine books of etudes, studies and compositions already in existence in the harp repertoire."
