What Hummel wanted to convey —
From “A Comprehensive Treatise on the Theory and Practice of Piano Playing”
Based on the 1828 second edition, I will present Hummel’s own discussions on educational perspectives and performance practices of his time, focusing on aspects other than musical examples and playing techniques.
So then, what kinds of topics are discussed in this “A Comprehensive Treatise on the Theory and Practice of Piano Playing”?
To some extent, this can be anticipated by looking at the table of contents.
