Abnormal Playing Techniques in the String Quartets of Helmut Lachenmann
David Alberman · Contemporary Music Review · 2004
This article is an attempt to classify and describe the array of new techniques that Helmut Lachenmann has invented or exploited for string instruments. I mention features of each extended technique and give examples of where they occur in the three string quartets. I have also created a chart to help readers identify these new sounds.
