disputed portrait of our friend Sebastian by Johann Ernst Rentsch the Elder (d. 1723) painted c. 1715, which would make him 30 years old here. Sebastian most likely wrote the cello suites when he was at Köthen (1717-1723)

Our friend Sebastian was born this time of year in 1685 – on March 21 or March 31, depending on whether you recognize Old or New Style (Julian or Gregorian) calendar conventions for commemorating things that happened centuries ago. I have friends who insist that one or other date is correct, but for me it doesn’t matter – for me, every year for many years now I have observed a quiet little personal eleven-day period of reflection on Bach’s music between March 21 and March 31. Each day for eleven days, I set aside some time to both play some of Sebastian’s music (on piano, harpsichord, or lute) and to intentionally listen to some of my favorite recordings of pieces that have touched me deeply.
