In the second half of the 20th century, historical informed performance practice became the leading way in rendering “early” organ music. In advance to this development a so called modern approach had been presented, documented with “almost authentic Bach playing á la Straube” by Straube's student Käte van Tricht in her 1945 to 1992 recordings.
So-called "extended techniques" have suffered a consistent lack of understanding from a theoretical, historical and practical point of view.

In our culture, vocal harmonics fuction as independent musical elements since only a few decades. Thresholds of the audible explores the changing relationship between singers, listeners and harmonics. As a research method a series of compositions (Nulpunten/’Zeropoints’) has been developed, which attempt to make a fresh approach to overtone singing and to the sonic source material of the human body.
Although the guitar has been part of the classical music tradition for centuries, writing for the guitar remains a formidable challenge for many composers. Where orchestral instruments have a long history of scoring guides that help composers develop their craft, the number of studies dedicated to guitar scoring remains scarce. This has led to a myriad of scoring problems in guitar works written by non-guitarist composers, often evidenced in unplayable passages and underdeveloped textures.
