Eight-string guitar Novax Guitars. Five of the strings are tuned to the standard guitar's upper five (A, D, G, B, E), while three of the strings are tuned to the standard bass guitar's three lowest (E, A, D). The bass and treble sections have separate pickups and are sent to separate amplifiers. Hunter also has a ten-string guitar based on the same principle—a combination of standard six-string guitar and standard four-string bass. The eight-string guitar is used by modern heavy metal guitarists such as Fredrik Thordendal and Mårten Hagström of Meshuggah, Dino Cazares of Fear Factory, Stephen Carpenter of Deftones, Greg Burgess
The Well-Tuned Piano third, consider that 5:4 is equivalent to 386 cents () and 9:7 is equivalent to 435 cents (). This difference is audible to the listener by comparing the tuning for each pitch of the western chromatic scale with the chromatic scale used in "The Well-Tuned Piano". "The Well-Tuned Piano" is based on a pitch lattice of perfect fifths and harmonic sevenths. "The Well-Tuned Piano", being improvisatory in nature, as well as ever-changing, has no specific form. The closest a listener can come to understanding the structure of Young's piece is by studying the liner notes from the 1981 Gramavision recording.
