<span>Johan Sebastian Bach
was German composer and musician in period of Baroque (17th

a standard by which to judge music from this time period. Bach was even
regarded as one of the greatest composers of all time since 19th

Concertos”, “Goldberg Variations”, and vocal music “St Matthew Passion” and the
“Mass in B minor”.</span>
