The Well-Tempered Clavier - Musical Style and Content

Musical Style and Content

Musically, the structural regularities of the Well-Tempered Clavier encompass an extraordinarily wide range of styles, more so than most pieces in the literature. The Preludes are formally free, although many individual numbers exhibit typical Baroque melodic forms, often coupled to an extended free coda (e.g. Book I preludes in C minor, D major, and B-flat major).

The Preludes are notable also for their odd or irregular numbers of measures, both as to phrases and as to the entire length of a given Prelude.

Each fugue is marked with the number of voices, from two to five. Most are three- and four-voiced fugues. The fugues employ a full range of contrapuntal devices (fugal exposition, thematic inversion, stretto, etc.), but are generally more compact than Bach's fugues for organ.

The best-known piece from either book is the first prelude of Book I, a simple progression of arpeggiated chords. The technical simplicity of this C Major prelude has made it one of the most commonly studied piano pieces for students completing their introductory training. This prelude also served as the basis for the Ave Maria of Charles Gounod.
