This website offers free downloads of the complete extant organ works of Johann Sebastian Bach, recorded by Dr. James Kibbie from 2007 to 2009 on original baroque organs in Germany.

Exactly which works should be recorded? More than 250 years after Bach’s death, it is by no means certain exactly what he composed. The selection of works for this series draws on the Bach Werke Verzeichnis, Kleine Ausgabe (Breitkopf & Härtel, 1998), supplemented by other recent scholarship, including the work of Prof. Christoph Wolff and the research of the Johann-Sebastian-Bach-Institut Göttingen. Bach’s organ transcriptions of works by other composers have been included. Dr. Kibbie has also recorded those works which survive only as fragments, leaving these works incomplete as they exist in the manuscript sources.

For the “dubious” works which may or may not be by Bach, Dr. Kibbie has chosen which to record, including especially those long associated with the Bach canon, such as the Pedal-Exercitium, the Kleines harmonisches Labyrinth and the “Gigue” Fugue. On the other hand, some works long identified with Bach are now widely regarded as spurious, and so have not been included (for example, the Eight “Little” Preludes and Fugues).

Bach composed for organs ranging from the 17th-century North German instruments he admired in his youth to the mid-18th-century organs he himself helped design during his Leipzig years. For these recordings, Dr. Kibbie has selected seven historically significant instruments matched to the varying stylistic requirements of the Bach repertoire.

Insomnia, so what better time to repost something and break my silence?

Last night on “60 Minutes” (HT IndianaJim) President Obama said to interviewer Steve Croft about tax cuts:

Steve, the math is the math. You can’t lower rates and raise revenue, unless you’re getting revenue from someplace else.

This answer reveals a deplorable understanding of either economics or math or both.

Revenues are the product of the “price” per unit (for example, the tax rate on a dollar of income) multiplied by the number of units for which that price is paid. If the percentage cut in the price per unit is smaller than a corresponding percentage increase in the number of units for which the now-lower price is paid, revenues don’t fall; they rise. The math, indeed, is the math.

Obama’s math works only in a bizzaro economic world – a world where changes in prices have no, or never more than a de minimis, effect on people’s behavior.

In that bizzaro world producers would never lower prices. (Why do so if lowering prices won’t result in a larger sales volume and higher revenues?) In that bizzaro world McDonald’s would charge $1,000 for each Big Mac. (Why not, if prices don’t affect people’s consumption choices?) In that bizzaro world no one would propose taxing cigarettes to discourage smoking. (Why do so if higher prices don’t affect behavior?) And in that bizzaro world no one would ever call for higher tariffs to protect domestic producers from foreign competition. (Why do so if raising tariffs does not reduce the number of imports that people buy?)

It’s one thing to question a claim’s empirical relevance; it’s quite another to dismiss it categorically as being an alleged violation of the laws of mathematics.

What sorry testimony about the “reality-based” political community that the current President of the United States believes it to be simply a matter of “math” that lower tax rates necessarily result in lower tax revenues.
