This is a collection 
                of pieces composed by Dexter Morrill, 
                between 1973-1995, in connection with 
                Stanford University and its Center for 
                Computer Research in Music and Acoustics. 
                Since 1971 Morrill has been Director 
                of the Computer Music Studio at Colgate 
                University. 
              
 
              
Getz Variations 
                was written for the great Jazz tenor 
                saxophonist Stan Getz and this recording 
                of the piece was made at an open-air 
                concert. As well as his considerable 
                experience in the field of computer-generated 
                music, it should be mentioned that as 
                a young man Morrill studied at the Lennox 
                School of Jazz (where his teachers included 
                Dizzy Gillespie and William Russo) and 
                is also the author of A Guide to 
                the Big Band Recordings of Woody 
                Herman 1936-1987 (1990). 
                He is, thus, well fitted to attempt 
                a marriage between computer music and 
                jazz. The Getz Variations are 
                in four movements. Throughout Getz improvises 
                against a setting devised by Morrill; 
                in performance Getz’s improvisations 
                were heard through the same speakers 
                as the accompaniment. In the first movement 
                (‘Echoes’) the accompaniment consists 
                both of ‘sampled’ recordings by Getz 
                himself and new computer sounds; in 
                the second – on which Getz’s playing 
                is particularly impressive – the accompaniment 
                is made up of computer generated bass 
                and percussion and an additional electronic 
                instrumental line. The third movement 
                (‘The Lady from Portola’) alludes to 
                the period of Getz’s greatest commercial 
                success, as a player of the bossa nova 
                during the 1960s – ‘The Lady from Portola’ 
                is clearly a relation of ‘The Girl from 
                Ipanema’. In the last movement (‘Windows’) 
                Getz improvises – very interestingly 
                - against fragments of one of his most 
                famous solos, from 1946, on ‘Summer 
                Sequence’ with Woody Herman. Getz’s 
                improvisations are the most engaging 
                features of these Getz Variations, though 
                Morrill certainly deserves the credit 
                for preparing the accompaniments which 
                stimulated them. 
              
 
              
Sea Songs contains 
                settings of texts by Ezra Pound (twice), 
                Aga Shahid Ali and Yvor Winters. The 
                performances by Margaret Chowning are 
                accompanied by sounds synthesised by 
                Morrill. Chowning’s voice is changed 
                by the so-called Radio Baton, held in 
                the soprano’s hand as she sings, which 
                transmits her voice to a microphone 
                and a processor. Merrill’s melodies 
                are largely tonal, even traditional, 
                but the sound has a slightly unfocused, 
                shimmering sound – by no means unfitting 
                for texts which speak of the "thin 
                glitter of water", "the shallow 
                eddying fluid" and the "blue 
                water dusky". 
              
 
              
In Salzburg Variations 
                a ‘live’ instrumentalist plays the celletto 
                (a kind of electronic cello, invented 
                by Chris Chafe in the 1990s, see link), 
                Morrill adds a layer of sound by selecting 
                – in real time - from some of the sounds 
                produced by the MIDI controls on the 
                celletto and both are heard against 
                a pre-recorded computer background by 
                Morrill. The results include some interesting 
                and striking passages, but come close 
                to outstaying their welcome. 
              
 
              
Quartet uses 
                two live musicians (a violinist and 
                cellist) and replaces the second violin 
                and viola of the orthodox quartet by 
                two loudspeakers through which pre-recorded 
                computer materials by Morrill are heard. 
                The interplay of voices - but not the 
                actual sounds – mimics the conversation 
                of a traditional quartet and are suggestive 
                of ways in which the computer might 
                contribute to chamber music. I found 
                this the most thought-provoking of the 
                pieces on the CD. 
              
 
              
Chowning is 
                an early piece, quasi-percussive. While 
                of interest as a document in the history 
                of computers and music, it doesn’t have 
                much to offer, I’d guess, that is likely 
                to command repeated listenings. 
              
 
              
For those whose minds 
                are not closed against the use of computers 
                this will surely be a quietly interesting 
                disc, uneven in realised achievement 
                but almost always interesting and genuinely 
                experimental in an intelligent fashion. 
                Getz Variations and Quartet 
                – at least – are interesting and satisfying 
                pieces.
