BRIEF SUMMARY
This application is the national phase of international application PCT/BE97/00077 filed Jul. 3, 1997 which designated the U.S.
FIELD OF THE INVENTION
The present invention relates to a device and a method for performing or interpreting a work of music, starting from a traditional score, used as if it was a keyboard, accessible to interpreters with no particular experience in practising an ordinary musical instrument and in the knowledge of rules of musical writing.
According to the present invention, an interpreter can in an easy and performing way, play a work of music, by touching sequentially, with a special pointer, the notes displayed on the staff lines of the traditionally written musical score.
BACKGROUND OF THE INVENTION
There are known systems for teaching music where staff lines are displayed with, on the staff, the notes of the scale, said notes as well as the board bearing them, being built in such a way that, being electrically connected to a tone generator, each note on the board is sounding and heard with the corresponding tone, each time it becomes touched. The note may be touched either with the finger or with a pointer or wand, electrically connected by a wire to the tone generator. Several patents have been granted for devices of that kind among them, the German patent 2941630; several other patents have been granted for improvements, sometimes of details.
The present invention uses a principle analogous to the one described in the German patent 294 1630 and the abovementioned improvement patents, not--or not only--for illustrating in a sounding way the writing of the musical scale, but for properly playing, i.e. interpreting, a whole work of music, performing it even with more virtuosity and sensibility than if played on the keyboard of a traditional instrument. Furthermore, this interpretation can be performed with less musical knowledge, and less practice, than when a traditional instrument is used.
SUMMARY OF THE INVENTION
According to the invention, there is used the written score, or music sheet, of the work to be played as the composer or arranger has written it on paper--by touching every note sequentially, by means of the point of a special sensitive wand, or pointer, which is held in the hand.
The written conventional music sheet, on paper or equivalent material, is processed by successive pages, one page at a time. The page is laid on a digital graphic tablet, like the ones existing in computer hardware trade, associated with a small computer of following composition. From said composition and from an appropriate program, the graphic tablet recognizes any X and Y axis position of points touched by an appropriate pointer, of pencil structure, held in the hand of the interpreter, and particularly the positions where a note of the melody to be interpreted is situated. The signal identified by the computer in that way, induces the emission of a signals stream, like MIDI signals, sent into a tone generator which outputs the corresponding note.
The device is then acting as a "keyboard" allowing the interpreter to play the notes he chooses (provided they are on the music sheet) and according to his will, in what concerns their succession and the tempo. He may, in particular, like on a real keyboard, skip a note, come back to a note, etc.
The pointer has a transducer which transmets to the computer, according to the interpreters will, the emission order for signals controlling one or several sound parameters of the melody. Typically such a transducer is a pressure sensor of which the signal translates the pressure exerted by the interpreter in the direction of the graphic tablet, via an axial rod in the pointer, into control of the melody sonic volume. Other transducers, for instance fitted at the pointer sides, may actuate other sound parameters like vibrato, reverberation, etc.
Furthermore, the axial rod in the pointer, linked to its pressure sensor, and for which the travelled stroke is function of the force exerted by the interpreter, is advantageously provided with two
