Ausführliche Anweisung

Ausführliche theoretisch-practische Anweisung zum Pianoforte-Spiel (Complete Theoretical and Practical Guide to Piano Playing) — Hummel's comprehensive piano method published in 1828, one of the most important treatises on piano technique and performance practice of the 19th century. It covers fingering, touch, ornamentation, improvisation, accompaniment, and aesthetics, and gives specific guidance on the style of Mozart and Clementi. It remained influential throughout the century and is a primary source for historically informed performance of Classical-era piano music.

Reading Hummel's method alongside his music transforms the experience of playing it. His ornament tables, fingering choices, and descriptions of touch are specific and practical. In particular, his discussion of how to achieve 'singing tone' on the fortepiano — through careful finger pressure and minimal use of arm weight — is directly applicable to his sonatas and concertos.
