1948 __ Free Music Machine
‣ Comment : Percy Grainger's innovations, which seem avant-garde even today, included work with Hammond organs, electronic sound-producing mechanisms, and hand-built machines to create "free music" (i.e. unconstrained by traditional pitch or beat). The 'Free Music Machine' was created by musician and singer Burnett Cross and the Australian composer Percy Grainger. Grainger a virtuoso Pianist and pupil of Busoni, had been developing his idea of "free music" since 1900: based on eighth tones and complete rhythmic freedom and unconventionally notated on graph paper. Grainger had experimented using collections of Theremins and changing speeds of recorded sounds on phonograph disks and eventually developed his own instruments. Graingers experiments with random music composition predated those of John Cage by 30 years with "Random Round" written in the 1920's. Graingers first experiments used a Pianola "player piano" controlling three Solovoxes by means of strings atached to the Pianola's keys, this combination was abandoned as it was not possible to create a continuous glissando effect from the Pianola. Grainger started work on a more elaborate but eccentric machine in collaboration with Burnett Cross and his wife, Ella Grainger. The Free Music Machine was a machine that controlled the pitch, volume and timbre of eight oscillators.Two large rollers fed four sets of paper rolls over a set of mechanical arms that rolled over the cut contours of the paper and controlled the various aspects of the oscillators. (Simon Crab, 120 Years Of Electronic Music) — Graingers notes, April 1952: 8 oscillators, able to play the gliding tones and irregular (beatless) rythms of Graingers FREE MUSIC (first thought of around 1892), are manipulated by paper graphs, towered discs and metal arms.A sheet of light brown wrapping paper 80 inches high (called "main paper"), is rolled continually from the "Feeder" revolving turret into the "Eater" revolving turret, passing through a metal cage on its way (the cage keeps the Main Paper, the graphs and ths discs in place). Each of the 8 oscillators has its own special pitch control graph and sound strength control graph. To the front of the main paper are attached 4 pitch-control graphs (mauve and greenish paper) and 4 tone-strength control graphs (pinkish paper), their top edges cut into "hills and dales" in accordance with the intervals & tone strength desired. These graphs operate oscillators 1,2,3,4. To the back of the Main Paper are attached 4 additional pitch control graphs and 4 additional tone strength control graphs, operating oscillators 5,6,7,8 The bottoms of these 16 graphs are sewn onto the main paper at various heights but the top of each graph is left unattached. Into each pouch thus formed (between the main paper and thegraph paper) is inserted a towered metal disc, the tower riding the upon the top edge of the graph & following its up and down movements. These movements are passed on to the axle and tone strength control box of each oscillator by means of metal arms, causing whatever changes in pitch and volume are intended. The blue-and-white discs controlling tone strengths are smaller than the variously coloured discs controlling pitch. In the above sketches the connecting electric wires are not shown.". — Grainger specified the requirements of his Free Music Machine to be: (1) To play any pitch of any size, half, quarter or eighth tones, within the range of 7 voices; (2) To be able to pass from pitch to pitch by way of a controlled guide as well as by leap; (3) Complex irregular rhythms must be able to be performed past the scope of human execution. Dynamics were to be precisely controlled; (4) The machine had to be to be run and maintained by the composer. -- Grainger was a continual experimenter picking up skills where necessary, amongst some of the eccentric instruments he produced were: (1) The first sliding pipes for playing gliding tones; (2) The electrical reproducing Duo Art grand piano 1932, for beatless music and irregular barring; (3) The portable folding harmonium; (4) The Burnett Cross movie-film gliding soundtrack, (abandoned as it did not allow Grainger to deal directly with the sounds themselves); (5) The Smith's Organ Flute Pipe, set up with hanging mops, rolling pins; (6) A range of experiments with reeds in boxes used as tone tools played with vacuum cleaners (1944-6); (7) The sewing machine and hand drill (to act as an oscillator for playing variable tones) October 1951; (8) The "Kangaroo Pouch", Grainger's own efficient framework design with the skatewheel mountings suggested by his collaborator, Burnett Cross and four vacuum-tube oscillators built by Branch, an electronics student, from the local White Plains High School; (9) The Butterfly Piano conversion tuned in 6th tones, (1952); (10) The electric eye tone tool Cross-Grainger 1957-59, the last remaining component.

‣ French comment : En 1945, Percy Grainger (1882-1961), élève de Busoni et le chanteur Burnett Cross débutent l'élaboration de la "Free Music Machine". Cet instrument fonctionne à partir de notations graphiques écrites le plus souvent de manière aléatoire sur des rouleaux de papier ayant pour fonction de contrôler 8 oscillateurs. Ainsi, Percy Grainger espérait mettre en pratique sa conception de la "musique libre", c'est-à-dire libérer les structures mélodiques et rythmiques des tyrannies traditionnelles de la musique occidentale. Toute sa vie, il poursuit cet objectif, en faisant notamment appel au hasard "random round", comme John Cage, et en étudiant de manière approfondie les différentes musiques traditionnelles. La dernière machine de sa création porte le nom de "Kangaroo-Pouch". (Sonhors) — Percy Grainger (auteur de « Country Gardens ») en collaboration avec Burnett Cross élabore l’idée d’une « Free Music Machine », une machine à faire une « beatless music with no standard duration », basée sur des sons en perpétuels glissements et dont la mélodie, le timbre et le rythme seraient complètement libérés des contraintes traditionnelles de l’harmonie, de la gamme et de la mesure. Dans sa production, des œuvres telles que « Love Verses from “The Song of Solomon” » contient de tels essais. (Communauté Électroacoustique du Canada, Projet d’Archivage Concordia PAC)
‣ Original excerpt : « Music is an art not yet grown up; its condition is comparable to that stage of Egyptian bas-reliefs when the head and legs were shown in profile while the torso appeared "front face" - the stage of development in which the myriad irregular suggestions of nature can only be taken up in regularised or conventionalised forms. With Free Music we enter the phase of technical maturity such as that enjoyed by the Greek sculptors when all aspects and attitudes of the human body could be shown in arrested movement. Existing conventional music (whether “classical” or popular) is tied down by set scales, a tyrannical (whether metrical or irregular) rhythmic pulse that holds the whole tonal fabric in a vice-like grasp and a set of harmonic procedures (whether key-bound or atonal) that are merely habits, and certainly do not deserve to be called laws. Many composers have loosened, here and there, the cords that tie music down. Cyril Scott and Duke Ellington indulge in sliding tones; Arthur and others use intervals closer than the half tone; Cyril Scott (following my lead) writes very irregular rhythms that have been echoed, on the European continent, by Stravinsky, and others; Schoenberg has liberated us from the tyranny of conventional harmony. But no non-Australian composer has been willing to combine all these innovations into a consistent whole that can be called Free Music. It seems to me absurd to live in an age of flying and yet not to be able to execute tonal glides and curves - just as absurd as it would be to have to paint a portrait in little squares (as in the case of mosaic) and not to be able to use every type of curved lines. If, in the theatre, several actors (on the stage together) had to continually move in a set theatrical relation to each other (to be incapable of individualistic, independent movement) we would think it ridiculous, yet this absurd goose-stepping still persists in music. Out in nature we hear all kinds of lovely and touching "free" (non-harmonic) combinations of tones, yet we are unable to take up these beauties and expressivenesses into the art of music because of our archaic notions of harmony. Personally I have heard free music in my head since I was a boy of 11 or 12 in Auburn, Melbourne. It is my only important contribution to music. My impression is that this world of tonal freedom was suggested to me by wave movements in the sun that I first observed as a young child at Brighton, Vic., and Albert Park, Melbourne. Yet the matter of Free Music is hardly a personal one. If I do not write it someone else certainly will, for it is the goal that all music is clearly heading for now and has been heading for through the centuries. It seems to me the only music logically suitable to a scientific age. The first time an example of my Free Music was performed on man-played instruments was when Percy Code conducted it (most skilfully and sympathetically) at one of my Melbourne broadcast lectures for the Australian Broadcasting Commission, in January, 1935. But Free Music demands a non-human performance. Like most true music, it is an emotional, not a cerebral, product and should pass direct from the imagination of the composer to the ear of the listener by way of delicately controlled musical machines. Too long has music been subject to the limitations of the human hand, and subject to the interfering interpretation of a middle-man: the performer. A composer wants to speak to his public direct. Machines (if properly constructed and properly written for) are capable of niceties of emotional expression impossible to a human performer. That is why I write my Free Music for theramins - the most perfect tonal instruments I know. In the original scores (here photographed) each voice (both on the pitch-staves and on the sound- strength staves) is written in its own specially coloured ink, so that the voices are easily distinguishable, one from the other. - Percy Aldridge Grainger, Dec.6, 1938. »
