 On June 25, 2019, "The New York Times Magazine" listed Joni Mitchell among hundreds of artists whose master tape recordings were reportedly destroyed in the 2008 Universal fire.While some of Mitchell's most popular songs were written on piano, almost every song she composed on the guitar uses an open, or non-standard, tuning; she has written songs in some 50 tunings, playing what she has called "Joni's weird chords".The use of alternative tunings allows guitarists to produce accompaniment with more varied and wide-ranging textures.
