Recorded samples

A Joy Forever - cover art Playing from Bach's fancy - cover art LaripS 1002 and 1003 were released January 4th 2006. Both are in the Bach temperament, recorded at Goshen College (Indiana, USA). #1002 is a set of three solo organ recitals, on three CDs. #1003 has one hour of music on harpsichord, plus a 20-minute section of bonus tracks on organ.

In Thee is Gladness - cover art LaripS 1001 "In Thee is Gladness" was released in January 2005. It is a program of music for organ and trumpet, performed in equal temperament on two organs in north Germany.

    Some of my musical priorities and principles are described at my older essays "Decoro, sprezzatura, grazia" and "What does a musical performer think about?".

    A sample recording is available performed by Robert Hill. The music is Bach's three-part invention in G minor, ornamented/interpreted using the principles in the essay The Craft of Musical Communication. It was recorded in a Swiss radio broadcast concert, May 2004, soon after I presented this Bach tuning to Dr Hill for his exploration. This performance on fortepiano is hosted at the "Institute for Musical Perception" web site by Keith Hill and Marianne Ploger, authors of that essay.

    Six other samples drawn from LaripS 1002 and 1003 are hosted at Oxford University Press's web site, as listening examples for the article "Bach's extraordinary temperament: our Rosetta Stone". See the outline page for details and that link.
