1/7Performer Biography
Luca Guglielmi, the harpsichordist, is also a conductor, composer, and musicologist, known for his historically informed interpretations and extensive discography.
Composer's Artistic Vision
Bach stated his purpose for composing 'The Well-Tempered Clavier' was for the 'profit of musical youth desirous of learning, and especially for the pastime of those already skilled'.
Composition History
J.S. Bach's 'Das Wohltemperirte Clavier' (The Well-Tempered Clavier), completed in 1722, expanded on an earlier work by Johann Caspar Ferdinand Fischer, increasing the number of keys from 20 to 24.
Recording & Production
This recording uses an original harpsichord from 1737 by Christian Zell, one of only three surviving instruments by the renowned German builder, preserved in the Museu de la Musica in Barcelona.
Interpretation
This recording applies the performance approach suggested by Bach's pupil Johann Philipp Kirnberger, who believed fugues were based on specific dance rhythms and figures.
Interpretation
The term 'Wohltemperirt' (well-tempered) in Bach's time referred to various subtly unequal temperaments, allowing different keys to have unique 'color palettes' of sound.
Composition History
Bach treated 'The Well-Tempered Clavier' as an 'open manuscript' throughout his life, continually adding corrections, reworkings, and performance instructions for his students.
