Pensam. palabra obra [online]. 2020, n.23, pp.104-129.  Epub 09-Mayo-2021. ISSN 2011-804X.  https://doi.org/10.17227/ppo.num23-10360.

This research broadens the concept of chromaticism in J. S. Bach's chorales; concept and materials that are currently included in music training programs at the undergraduate level. Thus, the idea that the Nonessential Chromaticism (NC), which is explained by the traditional theory, virtually doesn't exist in this music. On the contrary, all of these chromatic events have a Tonal Function (CTF) that is not explicit at the moment of their appearance, but it is part of a new chord or a melodic movement that belongs to a new scale or a new tonality. Likewise, this research attempts to explain the only six exceptional cases that serve to corroborate this theory because they can be grouped into some of the categories.

Palabras clave : chromaticism; Bach; chorales; tonal function and nonessential.
