In the first decades of the 19th century, the string quartet became far more important than the flute quartet; as a result, very few new works were composed until the 20th century. Until the works of Volkmar Andreae (quartet Op. 43) and Gottfried von Einem (quartet Op. 85), the 20th century was also somewhat lacking in compositions of this type. Works from the 21st century have included the "Air and Adorable Blues" by Blaž Pucihar, "Broken words" (2000) by Sophie Lacaze and "In blauen Linien" (2012) by Graham Waterhouse.
