Very few composers are as studied, interpreted and covered as Bach. The German composer had a huge influence on how music evolved in the early eighteenth century, and wrote his baroque pieces with a mixture of rigor and virtuosity that still makes them relevant to the musicians of today (and to the ringtones of today with his inevitable Well-Tempered Clavier). Although he was an organist first and foremost, he also played the viol, the violin and sang. Therefore, he wrote timeless works under many forms.
