Intervallic Tunings for Twelve-String Guitar [EPUB ebook] 

Intervallic tunings are an unusual and fascinating alternative to conventional guitar tunings. Recommended for twelve-string guitar players, this volume examines the history of intervallic tunings, as well as how to use them on the twelve-string guitar. Twelve-string guitars are an ideal instrument for intervallic tunings. Briefly stated, intervallic tuning systems tune the string courses to non-standard intervals other than octave or unison. To date, very few guitar players have adopted them. The text includes a brief history of intervallic tunings, an examination of different intervallic tuning systems, and a concise section of music theory on the fretboard cartography of chords and scales in intervallic tunings. Includes diagrams, glossary and bibliography.
