Joshua Rifkin

Cover of Scott Joplin's Magnetic Rag, published 1914

Rifkin's Joplin albums (the first of which was Scott Joplin: Piano Rags in November 1970 on the classical label Nonesuch)[4]—which were presented as classical music recordings—were critically acclaimed, commercially successful and led to other artists exploring the ragtime genre. It sold 100,000 copies in its first year and eventually became Nonesuch's first million-selling record.[5] The Billboard "Best-Selling Classical LPs" chart for September 28, 1974 has the record at No. 5, with the follow-up "Volume 2" at No. 4, and a combined set of both volumes at No. 3. Separately both volumes had been on the chart for 64 weeks.[6] The album was nominated in 1971 for two Grammy Award categories: Best Album Notes and Best Instrumental Soloist Performance (without orchestra), but at the ceremony on March 14, 1972, Rifkin did not win in any category.[7] Rifkin's work as a revivalist of Joplin's work immediately preceded the recording and subsequent performances of The Red Back Book, orchestrations of 15 rags, by Gunther Schuller and The New England Ragtime Ensemble (originally the New England Conservatory Ragtime Ensemble); and the later adaptation of Joplin's music by Marvin Hamlisch for the film The Sting (1973).[8] In 1979, Alan Rich in the New York Magazine wrote that by giving artists like Rifkin the opportunity to put Joplin's music on record, Nonesuch Records "created, almost alone, the Scott Joplin revival."[9]

In August 1990, Rifkin recorded a CD for the Decca label (catalog number 425 225) featuring rags by two of the other major composers of ragtime, Joseph Lamb and James Scott, and also tango compositions by the Brazilian composer Ernesto Nazareth.

Rifkin is best known to classical musicians for his thesis that much of Johann Sebastian Bach's vocal music, including the St Matthew Passion, was performed with only one singer per voice part, an idea generally rejected by his peers when he first proposed it in 1981. In the 21st century, the idea has become influential, although it has not achieved consensus in the field. The conductor Andrew Parrott wrote a book arguing for the position (The Essential Bach Choir; Boydell Press, 2000; as an appendix, the book includes the original paper that Rifkin began to present to the American Musicological Society in 1981, a presentation he was unable to complete because of a strong audience reaction). Bach scholars as Daniel Melamed,[10] David Schulenberg,[11] and John Butt[12] have argued in its favor.

Other conductors and ensembles have followed Rifkin and Parrott in mounting performances that use some form of the vocal scoring argued for by Rifkin. Among them are: Butt with the Dunedin Consort (Magnificat, Cantata no. 63, Mass in B minor in Rifkin's critical edition of the work, discussed below, the St. John Passion, and St Matthew Passion), Konrad Junghänel (Mass in B minor, several cantatas, St. John Passion, and the motets), Sigiswald Kuijken (Mass in B minor, St. John Passion, St Matthew Passion, Christmas Oratorio, and the beginning of a cycle of the complete Bach cantatas), Paul McCreesh (St Matthew Passion, Magnificat, Easter Oratorio, and several cantatas), Monica Huggett (St. John Passion), Eric Milnes, who has begun recording the complete cantatas cycle with one singer per part, Marc Minkowski (Mass in B minor), Lars Ulrik Mortensen (Mass in B minor), Philippe Pierlot with the Ricercar Consort (Magnificat, masses and cantatas), Jeffrey Thomas (who has also often used multi-voice choirs), Jos van Veldhoven (Mass in B minor, St Matthew Passion), Matteo Messori (Christmas Oratorio, cantatas, motets), and Peter Kooy in the motets.

Rifkin himself has recorded Bach's Mass in B minor—his 1981 Nonesuch recording won the 1982–83 Gramophone Award in the Choral category—Magnificat, and cantatas nos. 8, 12, 51, 56, 78, 80, 82, 99, 106, 131, 140, 147, 158, 172, 182, 202, 209, 216, and others, for the Nonesuch, Mainach, L'Oiseau-lyre, and Dorian labels, all with his Bach Ensemble and various singers.

One of Rikfin's widely accepted findings, which he published in 1975, is that Bach's St Matthew Passion was first performed on Good Friday in 1727, not 1729 as was previously believed.[13] Rifkin's scholarly critical edition of Bach's Mass in B minor was published by Breitkopf & Härtel in November 2006. It is the first edition to follow strictly Bach's final version from 1748 to 1750, not intermixing readings from the 1733 Missa (the first version of the Kyrie and Gloria), and posits novel solutions to removing edits made posthumously by Bach's son C.P.E. Bach.

Rifkin has done extensive research on the orchestral suites of Bach, notably arguing in detail that No. 2 in B minor, BWV 1067, is based on an earlier version in A minor in which the solo instrument was not the flute.[14] Rifkin has created reconstructions of J.S. Bach's posited Oboe Concerti: for oboe, strings, and continuo in D minor, from BWV 35, 156, 1056 and 1059; in A major for oboe d'amore, strings, and continuo from BWV 1055; in E-flat major for oboe, strings, and continuo from BWV 49, 169 and 1053. All the original movements are keyboard settings. They reflect the Baroque oboe idiom convincingly. In this form, they evince the influence of the Venetian school, notably Marcello, Corelli, and Vivaldi.[15]

In a paper published in the Bach-Jahrbuch in 2000, Rifkin argued that the cantata Nun ist das Heil und die Kraft, BWV 50 was not written by Bach, but by an as-yet-unidentified composer.[16]
