Keyboard concertos by Johann Sebastian Bach practice that lasted until the early nineteenth century, namely the soloist played along with the orchestra in "tutti" sections, only coming into prominence in "solo" passages. The works BWV 1052–1057 were intended as a set of six, shown in the manuscript in Bach's traditional manner beginning with 'J.J.' ("Jesu juva", "Jesus, help") and ending with 'Finis. S. D. Gl.' ("Soli Deo Gloria"). Aside from the Brandenburg concertos, it is the only such collection of concertos in Bach's oeuvre, and it is the only set of concertos from his Leipzig years. The concerto BWV 1058 and fragment BWV 1059 are at
Horn Concertos (Mozart) or 1786 (Humphries 2000, 87). Given the duration of the concertos (no more than 20 minutes each) it is quite common to find these horn concertos on the same CD, or in boxed sets of Mozart's concertos for wind instruments or even all his concertos. The Naxos Records CD "Complete Works for Horn & Orchestra" includes, besides the concertos, three rondos for horn and orchestra completed by musicologists. When a CD has only one of the horn concertos, it is typically paired with another concerto for a wind instrument also by Mozart. Horn Concertos (Mozart) The Horn Concertos by Wolfgang
