F. A. Kummer had in his introduction, described his Violoncello Method as primarily a self teaching book for students who had access to only ‘scant or inefficient’ teaching opportunities (or taught oneself strictly through You-tube had such a thing then existed). If one stayed true to his path and studied the exercises in order, one would become a competent cellist with only the occasional check-up of a teacher to make sure one did not stray too far from the mark.

I often suspect that perhaps the students from the gymnasium of his day might have had a more thorough musical foundation than American students do.

It does seem that in addition to regular tuition from a professional cellist, that the adult amateur today has many resources from which to learn, but chief among them is a good teacher who can help him/her navigate fortunately not alone, through Kummer.
