Title: Symphonic Prelude (Bruckner)
Content:  The Symphonisches Präludium (Symphonic Prelude) in C minor is an orchestral composition by Anton Bruckner or his entourage, composed in 1876. The work was discovered shortly after World War II. Heinrich Tschuppik, who found the orchestral score of the work in the estate of Bruckner's pupil, attributed the authorship to Bruckner. Thirty years later, Mahler scholar Paul Banks, who knew only a four-stave reduction of the work, proposed that the work might be attributed to Mahler. While the exact circumstances of the composition of this Prelude have not been determined, it is certain to have been composed within the circle of Bruckner and his students at the Vienna Conservatory of Music. Based on the original orchestral score, it seems likely that the work was at least sketched by Bruckner, possibly as an exercise in orchestration for Krzyzanowski.
Title: Island Prelude
Content:  Joan Tower says that she found her inspiration for Island Prelude in oboist Peter Bowman's "exceptionally lyrical playing and also Samuel Barber's wonderfully controlled Adagio for Strings".

Title: Prelude for Clarinet (Penderecki)
Content:  This composition is in one movements and takes approximately 3 minutes to perform. It is marked lento sostenuto at the beginning, which is the general tone of the piece. The composition is notated without bar lines, which transforms the piece into a pseudo-improvisatory composition, leaving the performer great room for expression. It starts with a low G being played in a pulsating manner and develops from there a sighing tone adding higher notes. Then the general mood of the composition becomes more fast and rampant, until a high-pitched glissando is reached, returning slowly to the G played at the beginning.
