At 368 pages, Beyond Salsa for Ensemble, Vol. 1 is the most ambitious of the 15 volume series. The course is designed for college and high school Latin music ensembles and working salsa bands seeking to add modern Cuban "timba" and "songo" material and techniques to their repertoires. The course begins with the basic salsa groove and then presents two modern Cuban grooves (one in 2-3 clave and one in 3-2 clave), with note-for-note transcriptions for piano, bass, bongo, timbales, congas, and drums - all explained in careful detail in a conversational style. The next part of the book teaches 36 rhythm breaks, or "efectos," that can be added to any Latin arrangement. Again, every stroke of every part is meticulously transcribed, with lead sheets also provided for more experienced players. Finally, the book contains a complete chart for performance of a popular Cuban hit by the popular group Los Que Son Son, led by Pupy Pedroso, the subject of several of the Beyond Salsa Piano books."
