These two extraordinary works of late Mozart, KV 594 and KV 608, were both composed to fulfill a commission for a memorial exhibit in Vienna, to be played in a 'mechanical clock organ.? The term 'fantasy? or 'fantasia? came to be affixed to these works later, and is more descriptive and less cumbersome than the term Mozart listed in his own catalogue, 'Ein Stüke für ein Orgelwerk in ein Uhr.? They are also variously titled 'Adagio und Allegro in f für ein Orgelwerk? and 'Allegro und Andante (Fantasie in f) für eine Orgelwaltze.?The first of these, composed between the monumental String Quintet in D and the Piano Concerto in Bb KV 595, is an A-B-A form, comprised of an f minor Adagio opening and closing, with a contrapuntal Allegro at its heart. KV 608 is more complicated, opening with an f minor section reminiscent of a French Overture, followed by a fugue in f minor, then an Andante aria, followed by a return to the opening and then a more complex version of the fugue.Despite the frustration that Mozart expressed (in a letter to Constanze) with the sound world of these mechanical devices, KV 594 and 608 are remarkable works which stand at an intersection, incorporating what he learned about counterpoint studying at the foot of Bach, while looking ahead to the emotional and harmonic poignancy of Schubert. / Quintette A Vent

Programme Note WHIRLS´ WORLD (1970) for wind quintet. 'Whirl´s World' was composed in 1970 as one of a series of works which explored the so-called musical ´difference-phenomenon´. This term (which I coined in connection with a series of lectures in California that year) indicates a motivic duplicity in which two - often very simple - melodic ideas come ´out of phrase´ with each other giving rise to a course of constantly changing conditions. In Whirl´s World the difference phenomenon is heard from the beginning where a three-note motif and a four-note motif are set against each other. It all proceeds lake a lightning-fast series of chess moves; first notenumber 1 of the three-note motif is moved then note number 1 of the four-note motif thereafter note number 2 of the three-note motif - and so on. This fast opening flows into a slow section in which the differences now appear as ´fluctuations´ between very closely related tones (of which one is sung by the musician). There is only one movement built up as an organic growth from slow to furiously fast whirling and back again to slow which can be heard as ´slow-motion whirls´ as a water-world of ripples and bubbles. All this is framed by the introduction described above and a corresponding conclusion in which the movement is now descending ending in the resolute bass full-stop. Per Norgård
