4(Easy Guitar). In the early 1700s, Bach's chorales enchanted listeners with their inventive harmonies, chromaticism, contrapuntal motion, and changes of tonal center. Since that time, music students the world over have studied the chorales as a paragon of "common practice" harmony and voice leading. And by virtue of their sublime beauty, musicians continue to perform the chorales to this day. The four-part texture of the chorales can make their performance on guitar with its fingering limitations somewhat problematic. But by sometimes thinning the texture to three or two parts, and sometimes inverting the lower parts (allowing the alto or tenor to temporarily serve as the bass), we've created easy-to-play classical guitar solos that capture all the interest and beauty of Bach's original compostitions. The book also includes recordings of every piece. The audio is accessed online using the unique code inside each book and can be streamed or downloaded. The audio files include PLAYBACK+, a multi-functional audio player that allows you to slow down audio without changing pitch, set loop points, change keys, and pan left or right.
