I believe that J.S. Bach wrote 6 Brandenburg Concertos:-

* Brandenburg Concerto No. 1 in F major, BWV 1046 * Brandenburg Concerto No. 2 in F major, BWV 1047 * Brandenburg Concerto No. 3 in G major, BWV 1048 * Brandenburg Concerto No. 4 in G major, BWV 1049 * Brandenburg Concerto No. 5 in D major, BWV 1050 * Brandenburg Concerto No. 6 in B flat major, BWV 1051

Suite for Solo Cello No. 1 in G Major, BWV 1007: I. Prélude by Bach.

The original piece is part of Bach's Orchestral Suite No. 3 in D major, BWV 1068 also known as "Air on the G string"

Lots of composers wrote masses. Some of the most famous masses are: Missa Solemnis by Beethoven Mass in B Minor by Bach Grand Mass in C Minor by Mozart
