Drop-2 chord forms have been used by guitarists in all musical genres for years. The concept refers to 4-way, closed voicings in root position or any inversion, dropping the second note from the top by 1 octave, hence the term "drop-2". In practice, a nifty guitar harmonic symmetry occurs as drop-2 chords are invariably played on any four successive strings, muting or avoiding the remaining 2 strings. This collection will open up a new world of harmonic possibilities for the beginning to intermediate guitarists, and will shore up the basics and provide added harmonic visualization for the advanced player. Chapter on comping the chord soloing applications are also included. Written in notation and tablature.
