Welcome to the official MAPLE Lab Tempo Visualizer for JS Bach’s Well
Tempered Clavier (Book 1). This tool is an online supplement to our
publication exploring the use of timing in this influential work (Poon & Schutz, 2015).
These values are based on a survey of tempi for seven different sets of
tempo markings – two by commentators and five by editors. These are grouped
as two categories on the horizontal axis. We have also included Dr. Willard Palmer’s
suggestions from this edition as a third category, in recognition to his
contribution to understanding this set of 48 pieces.
To see tempo guidelines for a particular piece, simply select the type
(Prelude/Fugue) and mode (Major/minor) as well as the pertinent pitch from
