Carl Philipp Emanuel Bach (8 March 1714 – 14 December 1788), also formerly spelled Karl Philipp Emmanuel Bach, was a German Classical period musician and composer, the fifth child and second (surviving) son of Johann Sebastian Bach and Maria Barbara Bach.
 His second name was given in honor of his godfather Georg Philipp Telemann, a friend of Johann Sebastian Bach.
Daniel Schiebeler (25 March 1741 – 19 August 1771) was a German writer, poet, librettist and Protestant hymnwriter.
 He wrote librettos for operas and oratorios, set by composers such as Georg Philipp Telemann, Johann Adam Hiller and Carl Philipp Emanuel Bach.
Carl Philipp Emanuel Bach: The Complete Works is a new critical edition of the music and keyboard treatise by C.P.E. Bach.
 The project was begun in 1998–99 in the wake of the aborted "Carl Philipp Emanuel Bach Edition," and many of the same eminent music scholars associated with the earlier incomplete edition have become involved with the new one.
 From 1999–2014, the new edition was chaired by Christopher Hogwood.
 After his untimely death in 2014, Robert D. Levin was appointed chair.
 The general editors are Darrell Berg (series I), Peter Wollny (series II, III, VII), and Ulrich Leisinger (series IV, V, VI).
 The edition is published by The Packard Humanities Institute.
 The current Editorial Guidelines (January 2015) are available in PDF format on the edition’s website: http://www.cpebach.org.
La Caroline, Wq.
 117/39, H. 98, is a character piece (or "piece de caractare") for solo keyboard in A minor, written by Carl Philipp Emanuel Bach.
 Bach wrote several character pieces which were often grouped together and published as a set.
 These character pieces were based on similar works composed by François Couperin.
 "La Caroline" along with "La Philippine" (Wq 117/34, H. 96) may have been named after his daughter Anna Carolina Philippina.
The Hamburgische Kapitänsmusik (Hamburg Captain’s Music) refers to a body of compositions by Georg Philipp Telemann.
 They comprise sacred oratorios and secular serenades. However, the oratorios were intended to be performed in a secular setting, the Hamburg Drillhaus, and their characters are almost exclusively allegorical.
 The "Kapitänsmusik" was written for the annual banquet (or "convivium") of the Hamburg militia captains.
 The works span the period from 1723 to 1766, although many of the manuscripts have now been lost, and in several of those years no banquet was held.
 Although Telemann’s grandson Georg Michael Telemann inherited many autographs and manuscript copies of Telemann’s vocal works, the rest of his musical estate, including the "Kapitänsmusik", was sold at an auction in Hamburg on September 6, 1769.
 Much of that material has since disappeared, and the auction catalogue has not survived.
 Of the 36 "Kapitänsmusiken" that Telemann wrote, only 10 oratorios (with nine complete oratorio–serenade pairs) plus a few separate pieces are extant today.
The Nannerl Notenbuch , or Notenbuch für Nannerl (English: Nannerl's Music Book) is a book in which Leopold Mozart, from 1759 to about 1764, wrote pieces for his daughter, Maria Anna Mozart (known as "Nannerl"), to learn and play.
 His son Wolfgang also used the book, in which his earliest compositions were recorded (some penned by his father).
 The book contains simple short keyboard (typically harpsichord) pieces, suitable for beginners; there are many anonymous minuets, some works by Leopold, and a few other composers including Carl Philipp Emanuel Bach and the Austrian composer Georg Christoph Wagenseil.
 There are also some technical exercises, a table of intervals, and some modulating figured basses.
 The notebook originally contained 48 bound pages of music paper, but only 36 pages remain, with some of the missing 12 pages identified in other collections.
P.D.Q.Bach is a fictitious composer invented by musical satirist "Professor" Peter Schickele.
 Schickele developed a five-decade-long career, performing the "discovered" works of the "only forgotten son" of the Bach family.
 Schickele's music combines parodies of musicological scholarship, the conventions of Baroque and classical music, and slapstick.
 The name "P.D.Q." is a parody of the three-part names given to some members of the Bach family that are commonly reduced to initials, such as C.P.E., for Carl Philipp Emanuel Bach.
 "PDQ" is an initialism for "pretty damned quick".
The Carl Philipp Emanuel Bach Chamber Orchestra (German: Kammerorchester Carl Philipp Emanuel Bach) is a German chamber orchestra, founded in 1969 in Berlin, dedicated to the music of Carl Philipp Emanuel Bach and his contemporaries.
Johann Sebastian Bach (26 September 1748 – 11 September 1778) was a German painter.
 He was the son of composer Carl Philipp Emanuel Bach and the grandson of composer Johann Sebastian Bach.
Michael Schneider (born 10 August 1953 in Nordhorn) is a German flautist, recorder player, conductor and academic teacher.
 He is especially connected with later Baroque repertoire such as the works of Telemann and with early Classical repertoire such as the works of Carl Philipp Emanuel Bach, and founded the orchestra La Stagione to perform and record such repertoire.
