In this article, Edward H. Tarr discusses the potential roles that trumpeters may have had during the era of Bach, not merely as trumpet performers but also as proficient multi-instrumentalists, with a particular focus on the horn. Additionally, Tarr conjectures about the plausible nomenclature and purpose of the coiled horn depicted in the famous portrait of Gottfried Reiche and in other pictorial representations from the same period.
