Sunflower"). Harmonies based on fourths and fifths also appear in folk guitar. On her 1968 debut album Song to a Seagull, Joni Mitchell used both quartal and quintal harmony in "Dawntreader", and she used quintal harmony in "Seagull". Quartal and quintal harmonies also appear in alternate tunings. It is easier to finger the chords that are based on perfect fifths in new standard tuning than in standard tuning. New standard tuning was invented by Robert Fripp, a guitarist for King Crimson. Preferring to base chords on perfect intervals—especially octaves, fifths, and fourths—Fripp often avoids minor thirds and especially major thirds, which are sharp in equal temperament tuning (in comparison to thirds in just intonation). Alternative harmonies can also be generated by stacking second intervals (major or minor).
