the pick. He synthesized plectrum and classical guitar technique. The pick is held in the normal way, but the remaining three fingers are used to play chords and counterpoint. Wayne often surprised audiences by using this method to play difficult Bach fugues and other pieces from classical music. His use of the technique for contrapuntal improvisation was an innovation. Chords Wayne's chord system is based on "generic" chord forms, forms that have the same sonority in all keys, and that do not rely on open strings or guitaristic peculiarities. Wayne observed that most guitar chords in common use do not have these properties and that the way most guitarists play a G7 chord, for example, sounds different from the way they play a C7 or an E7 due to the different arrangements of notes. The common ("cowboy") chords are popular because they simplify fingering, but they constrict musical options. Wayne avoided this problem. (He did also use "specific" chord forms when appropriate, but his system concentrated on chords with universal applications.) Most chord books have diagrams organized by chord name (A13, Gm7b5) or type (thirteenth, minor seven-flat-five). Under each heading are the fingerings that show the chord in alternative inversions and voicings, generally having little in common other than a shared set of notes. The guitarist memorises the forms, learning a few different ways to play each chord. Over time, through practical experience, the guitarist learns or decides when to use each form. When playing in Bb, such a guitarist will inevitably play with a very different set of voicings from what would be used in F or Eb, simply because the "normal" guitar chords in these keys have very different sonorities. Wayne tried to describe the "complete" scope of harmonic possibilities available on the fretboard, in all voicings, given conventional guitar tuning and a human left hand. Concepts In Wayne's system, a generic chord has four different notes. This includes chords like dominant sevenths, major sixths, and minor ninths, but not major or minor triads, or other "specific" triadic forms, which Wayne concluded were rarely useful for jazz. For chords containing five or more notes, such as thirteenths and ninths, Wayne removed the root, and other notes if necessary, to preserve the generic four-note form. Wayne's focus on four-note generic chords reflects the realities of left hand fingering on a six-string guitar. Four-note chords can be comfortably played in
