Del Sol Quartet
The Del Sol Quartet is a string quartet based in San Francisco, California that was founded in 1992.

In 2012, the San Francisco Chronicle described it as having been "a stalwart force for new music in the Bay Area, a vigorous and fearless champion of living composers without always getting its due recognition."

Del Sol has commissioned and premiered hundreds of works from a diverse range of international composers, including Frederic Rzewski, Mason Bates, Gabriela Lena Frank, Huang Ruo, Michael Harrison, Ben Johnston, Chinary Ung, Daniel Bernard Roumain, Kui Dong, Mohammed Fairouz, Theresa Wong, Erberk Eryilmaz, Tania León, Ken Ueno, Peter Sculthorpe, Pamela Z, Reza Vali, Per Nørgård.  

Current quartet members are Benjamin Kreith (violin), Samuel Weiser (violin), Charlton Lee (viola), and Kathryn Bates (cello).

Interest in Just Intonation 
The quartet demonstrates a particular interest in string quartet writing in just intonation, particularly in the work of American composer Ben Johnston, along with composers such as Michael Harrison, Theresa Wong and Mathew Rosenblum. They are currently the only string quartet touring multiple quartets by Ben Johnston, which are notoriously difficult, and were the first group to premiere Johnston's music at the Library of Congress in Washington, D.C in 2016.  In 2019, the quartet launched the "Pacific Pythagorean Music Festival", a music festival dedicated to works of just intonation. They were highlighted performers at the Pittsburgh "Beyond 2020: Microtonal Music Festival".
