About the Audios and Backing Tracks of our Series20 & 20

The Audios and Backings Tracks included in all the books of the Serie 20&20, aims to expand the study of each of the contents, using a precise sound methodology

With the purpose of not distracting the student's listening we have decided not to include in the harmonic part, the use of chromatisms, rhythmic subdivisions, opting for half and whole notes, as well as only the third and seventh corresponding to each chord.

In this way we will achieve an optimal understanding of the topics to be treated.

This methodology will also allow us to develop our harmonic and melodic ear according to the lesson, exercise or tasks.
