4(Guitar Method). An outstanding source for the technique and repertoire of the classical guitar, this book continues where Vol. 1 leaves off. It teaches: all notes in the upper position; tone production; advanced techniques such as tremolo, harmonics, vibrato, pizzicato and slurs; practice tips; stylistic interpretation; and more. The first half of the book deals primarily with technique, while the second half applies techniques to repertoire pieces. As a special bonus, this book includes 32 previously unpublished Parkening edition pieces by composers including Dowland, Bach, Scarlatti, Sor, Tarrega and others, plus three guitar duets. The audio files include 60 demonstration tracks. 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.
