Guitar tunings tuning is a tuning in intervals of perfect fifths like that of a mandolin or a violin; other names include “perfect fifths” and “fifths”. It has a wide range. Its implementation has been impossible with nylon strings and has been difficult with conventional steel strings. The high B makes the first string very taut, and consequently a conventionally gauged string would easily break. A variation of all-fifths tuning was used by jazz-guitarist Carl Kress. The bottom four strings are tuned in fifths and the top two strings tuned in thirds resulting in Bb-F-C-G-B-D. This results in tenor banjo formations on
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.
