As one can easily imagine, it would be very hard for a guitar student to start reading the scores of the traditional choro repertoire, most of them with large number of technical difficulties. It would be much better if they could start with some easier pieces - of intermediate level - in order to be presented to the choro language in a more gradual and appropriate manner. That is the main goal of this book. It has 13 studies (in the 13 more commonly used keys for the choro guitar) written in a reduced form and in the principal stylistic choro variants: besides real choros, there are polkas, maxixes, Brazilian tangos and xotis. The more used and characteristic rhythmical figurations are present in each of the studies as the principal. Also aiming at the simplification of execution, all studies were composed with only two voices (melody and bass) and with no chords (although harmonies are quite evident due to the choro melodic particularities). Includes access to online audio containing all 13 studies.
