Violin where a stopped note sounds a unison or octave with another (open) string, causing it to resonate sympathetically. Students often use these ringing tones to check the intonation of the stopped note by seeing if it is harmonious with the open string.

If the "A" is in tune, the "A" and the open D string should produce a harmonious perfect fourth. Violins are tuned in perfect fifths, like
String Quartets (Ligeti) work, like the first string quartet, but was also considered to be in six or three movements, with the three lasting about 12' + 3' + 6' minutes in total. The piece would be dedicated to the Arditti Quartet, entirely microtonal, inspired by the hyperchromaticism of Gesualdo, and inspired by melodic ideas from Burma, Uganda, Zimbabwe, Java, Bali, and Cameroon. It's also suggested that the entire quartet would be tuned in scordaturas based on harmonic partials, akin to the violin and viola in Ligeti's Violin Concerto. The fourth quartet would be dedicated to the Kronos Quartet, and be inspired by
