The discography pages of Cantata BWV 172 "Erschallet, ihr Lieder, erklinget, ihr Saiten!" (Ring out, you songs, resound, you strings!) for Whit Sunday [1st Day of Pentecost] on the BCW have been revised and updated.
The cantata is scored for soprano, alto, tenor & bass soloists; 4-part chorus; and orchestra of 3 trumpets, timpani, bassoon, 2 violins, 2 violas, organ & continuo. See:
Complete Recordings (32): http://www.bach-cantatas.com/BWV172.htm
Recordings of Individual Movements (27): http://www.bach-cantatas.com/BWV172-2.htm
The revised discography includes many listening/watching options to recordings directly from the discography pages, just below the recording details.
I also put at the BCW Home Page: http://www.bach-cantatas.com/
2 audios and 2 videos of the cantata. A short description below the audio/video image is linked to the full details at the discography pages.
I believe this is the most comprehensive discography of this cantata. If you are aware of a recording of BWV 172 missing from these pages, or want to correct/add details of a recording already presented on the BCW, please do not hesitate to inform me.
