Definitions

  • the present invention relates to the field of music, in particular the field of music education, and has as its object a device for making the rhythm and / or the beat perceptible.
  • Teaching rhythm or measure has a number of difficulties, and when interpreting a set of notes, it is often the rhythm or measure that causes the most problems.
  • FR-A-25 76 698 a musical language sentence has become known, which consists of modular boards, which enables the construction of the rhythmic themes by assembling the pieces. However, this sentence does not allow the rhythm to be made audible.
  • FR-A-25 32 775 also describes a musical composition set in which the cards representing the notes have a length which is proportional to the value of the rhythm. However, there is no sound restitution here either.
  • DE-A-l ⁇ 86 245 describes a device in which the modular elements in the form of the noteheads emit a constant tone stop. In this case, however, the tone remains until the next note. A pause cannot be played back because the sound persists until the next note, albeit decreasing.
  • Metronomes are also known which, for example, allow the clock or beat frequency to be set via a rotary or slide control which is provided with a scale labeled in the usual beat frequency values.
  • US-A-4,442,752 describes an electronic metronome in which the beat frequency is determined from the length of time for which a key of the metronome is held down. A tone sounds when the button is pressed, a second tone sounds when the button is released and then other tones periodically at the same time interval. At the same time, the value of the beat frequency set in this way is shown on a display.
  • a metronome can be used to solve three different tasks: - If, for example, the composer specifies the tempo to be played, it is used to produce a signal at the prescribed tempo.
  • the pace is usually given as the beat frequency and can be quickly and safely on metronomes using the rotary or slider controls mentioned above to adjust. In practice, however, this task is rather rare.
  • a metronome is used to give the musician, especially a pupil, an even beat. The musician should practice playing evenly without accelerating or braking.
  • metronomes are used to measure a played tempo.
  • the present invention has for its object to provide a novel device for clock and rhythm, with which, on the one hand, the aforementioned disadvantages of known metronomes are avoided, which in particular reproduces the rhythm while eliminating the dangers of an optical and / or an acoustic cycle sequence that allows creeping misinterpretation, and which on the other hand can be used as a device for music education and does not have the disadvantages of the devices mentioned at the beginning.
  • This object is achieved by a device with the features of claim 1, namely by a device with electrical drive means to generate a rhythm or a cycle with a preset beat frequency and to deliver this to the user of the device as a vibratory pulse sequence.
  • the device according to the invention has the advantage over known mechanical and electronic metronomes that the musician's perception of the clock is perceived via the sense of touch and pressure, which - as was surprisingly found - conveys the feeling of rhythm more securely and better than sense of hearing and sight.
  • FIG. 1 shows a schematic view of a device according to the invention
  • FIG. 2 shows a flow chart with different signals for clocking.
  • the device designated as 1 as a whole in FIG. 1 for reproducing a rhythm or bar as a vibratory see pulse sequence has a clock 2 with an electric motor referred to in more detail below and a control and regulating device 3 connected to the clock 2.
  • the clock generator 2 has a cylindrical housing 4 made of metal, plastic or wood, in which a direct current motor (DC motor) 5 with a drive shaft 6 is arranged.
  • a decentrically arranged vibrating element 7 is provided on the drive shaft 6, which vibrates the DC motor 5 when the device 1 is operating.
  • the DC motor 5 is arranged so tightly against the cylindrical housing 4 by means of bandaging means 8 that it receives and transmits the vibrations generated by the DC motor 5.
  • the DC motor 5 is connected via the electrical pole lines 9 and 10 to the control and regulating device 3 represented by a block in FIG.
  • the two lines 9 and 10 are connected to one another by a compensating means, in the present case by a resistance element 11.
  • the resistance element 11 has a motor power of, for example, 2 to 3 watts and 400 to 2,000 rpm (in the loaded state), for example 8,000 rpm, an ohm resistance of 50 ⁇ to 100 ⁇ , for example 70 ⁇ .
  • the compensation means or the resistance element 11 is used according to the invention to convert the vibrations generated by the rotation of the decentrically arranged element 7 in the direction of the arrow 12 into short pulses 13 defining the desired cycle, in such a way that the pauses between two pulses 13 each are of such a shape that they are as free as possible from vibratory run-out vibrations.
  • the control and regulating device 3 has an electronic circuit with a voltage regulator (with an output of, for example, 5 V), a potentiometer circuit, a signal generator, a counter, and a decoder and a driver. It is therefore essentially similar to the circuits used in known electronic metronomes.
  • an additional optical signal board 14 is connected to the control and regulating device 3, which optically reproduces the clock or pulse frequency generated by the DC motor 5 by means of lamps 15.
  • the signal board has a total of 4 lamps 15 which, when the clock generator 2 is in operation, light up in succession in succession as a result of the frequency generated.
  • the open-loop and closed-loop control device 3 has additional connections 18, 19, 20 for the signal controller designated with 21 for further signal boards, a total of four such connections being provided in particular when 1/4 cycles are generated.
  • the cylindrical housing 4 containing the DC motor 5 is brought into contact with the body of the musician, for example by the musician touching it with the foot or by means of a specially made belt around the waist, a thigh or fibula is worn.
  • the device according to the present invention has the decisive advantage over known metronomists that the recording time of the bar or the rhythmic Impulses are significantly reduced by the musician, which significantly improves adherence to the specified beat.
  • FIG. 2 shows schematically different pulse sequences 22, 23 and 24 which can be generated with the device according to the invention.
  • the DC motor 5 is continuously in the start-stop mode during the operation of the device 1 according to the invention.
  • the length of the vibratory pulse depends on the desired cycle type and cycle speed. For example, the 4/4 cycle is generated by alternating 1/8 pulses. If odd cycle types, such as 3/4 cycles, are desired, then, according to the invention, a second clock generator 2 is connected to the control and regulating device 3, which then essentially serves for orientation.
  • the device according to the invention can be used for music education.
  • a plurality of devices 1 of the type described above can be connected together to at least one control and regulating device 3, and groups of musicians or students can then perform various types of rhythm and cycle exercises with or without an instrument.
  • the device for reproducing a rhythm or clock as a vibratory pulse sequence described with reference to the drawing can be modified in various ways within the scope of the invention. It is thus possible to display the rhythm in the form of a digital display and, instead of using a DC motor of the type described, to use some other electrical or electromagnetic drive means which is capable of the clock or pulse frequency required for the rhythm to create.

Abstract

Dans les métronomes connus, la transmission de la mesure aux musiciens s'effectue de manière acoustique et/ou optique. Ce qui a pour inconvénient que, principalement les élèves qui étudient la musique ont des difficultés à garder la mesure prédéterminée par le métronome, étant donné qu'ils guettent la mesure du métronome d'une part, à l'oreille et/ou d'autre part, de manière optique et jouent de leur instrument en fonction de ce qu'ils guettent. Ce qui a pour effet que l'élève suit la mesure du métronome de manière décalée dans le temps, ce qui finit à la longue très fréquemment par induire des erreurs d'interprétation de la mesure et/ou la perte de la mesure. Ladite invention vise à mettre au point un dispositif d'un genre nouveau pour donner la mesure et le rythme, qui permette d'éviter les inconvénients précités propres aux métronomes connus. A cet effet, il est prévu un dispositif (1) comportant des éléments d'entraînement (5) destinés à produire le rythme et la mesure avec une fréquence de battement préajustée et de la restituer sous forme de séquence d'impulsions (13) vibratoires.
