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 and revised the volume multiple times.
The music selection is the best I could find for each level progressing in tiny well prepared steps, enjoyable to play. Exercises compact and only when needed.
Volume 1 contains No 1-50 on 57 pages - first position, bow and reading skills, each piece 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 Beethoven, Bach, Purcell, Sor, Carcassi, Gretchaninov, Gruber and Neidhardt.
Probably the most researched and tested way to start learning the cello!
To each number are Video cello lessons linked 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

The Harpsicle Harp method book is an excellent tool for learning to play the Harpsicle Harp or any size harp from the very beginning. No musical knowledge is necessary to use this method. All the music is written in the keys of C Major and A minor, so no sharping levers or pedals are needed. The guitar chords are displayed above the staff, so the students can add to the written music, or other instruments can accompany the harp. The music is graduated from two fingers to playing with both hands. The music is labeled to allow the students to gradually learn the notes and fingering without stress or frustration. The method contains lessons on the parts of the harp, tuning, stringing, and taking care of your instrument. Also included in the method are reading music, time signatures and counting, placing and bracketing, finger drills, and much more. There are also eighteen songs, starting from very easy and continuing to add to the music, as the student progresses. All songs have labeled notes, to help the students learn notes and fingering. Online video compliments the book, and follows up the written instructions, with video footage, so the student can visually see the method. Includes access to online video.
