Authoritative Urtext edition of Johann Sebastien Bach's Brandenburg Concerto No.3 In G Major BWV 1048. The six Brandenburg Concertos BWV 1046-1051 prized jewels of the world's musical heritage were written in 1721 during Bach s appointment in Cöthen. Of the six works Bach originally wrote earlier versions of numbers 1 and 5 which differ not only with regard to articulation but also at times different tones different rhythms instrumentation and of course form. These Urtext publications [BA 5201-BA 5206] taken from the New Bach Edition now give performers the possibility to play these earlier versions perhaps even alongside theversion known today.
