As a student 40 years ago I wrote a thesis about all existing cello methods. Then I started writing my own method by putting all positive aspects of all methods together.
The music selection is the best I could find for each level progressing in well prepared steps, enjoyable to play.
Exercises are compact and to the point, only used when needed.
Volume 3 contains No 64-100 on 60 pages - Learning to shift from Half position over first, second, third to 4th position. All pieces are written in form of a cello duo to be able to play with a friend or teacher together - includes traditional songs, fiddle tunes and compositions by Offenbach, Bach, Carcassi, Tchaikovsky, Moore, , Boccerini, Boris Fomin and Kummer.
To each number are video cello lessons published on Patreon. The links click through when viewed on phone, tablet or computer.
There are also Youtube recordings of all pieces as Cello Duos with fingerings and bowings as in the Cello Method, see https://www.youtube.com/playlist?list=PLa4x_CVYDVRXAnJJ_6HeRujngwTZ8cMEd

If you enjoyed Volume 1, you'll love Volume 2. Here are 10 more great pieces arranged for pure solo cello - no piano required! This collection has more than 30 minutes of classical and patriotic songs ideally suited for formal recitals, wedding celebrations, and background music gigs.

These are not just lame copies of the melody line; they are all fully worked out arrangements designed to be as rich as possible and to highlight the cello. As a professional cellist, I originally arranged these pieces for my personal use, and I have performed every one of them in public.

These are fairly challenging pieces; I would compare their difficulty to Bach Cello Suite #2 on the easy side and Bruch Cello Concerto on the harder side. But with some practice you will have some amazing additions to your solo repertoire.

Each of the songs in this collection is also available separately, but buying the full volume saves you over 60%.

Volume 2 contains the following:
1. Bach Toccata in D Minor

2. Brahms Hungarian Dance #5
3. Bizet Carmen Medley
4. Tchaikovsky Romeo and Juliet Introduction & Love Theme
5. Tchaikovsky Symphony #5, Finale (excerpt)
6. Debussy Clair de Lune
7. Sousa Washington Post March
8. Vieuxtemp Variations on "Yankee Doodle"
9. Meacham American Patrol
10. Smith The Star-Spangled Banner
