Definitions

  • the present invention relates to the production of music as a function of physiological parameters.
  • Systems which make prerecorded musical rhythms vary as a function of heartbeat. Such systems can be used to enable one's cardiac activity to be controlled when practicing sporting exercise.
  • Patent US-4 883 067 discloses the generation of musical signals as a function of the electroencephalogram (EEG) of a person, by means of electrical signals produced and converted into music.
  • This music comprises at least one voice which follows the contour of the EEG in real time, preferably by modulating the frequency of a tone or of a chord with the EEG signal. Additional voices are advantageously added, such as for example a voice using a modulation of timbre to indicate the relative frequency of occurrence of a particular feature of the EEG signal (col. 5, I. 5-11).
  • the method disclosed in this document is especially adapted to relaxation techniques or to therapeutic procedures.
  • Patent application EP-0 966 919 relates to a method of influencing the body, in particular in order to treat sleep problems. Biosignals such as an EEG, an electrocardiogram or the like (page 2, lines 49-52) are recorded in the course of a reference period.
  • This period is then divided into time intervals and, for each one of them, a frequency spectrum is calculated.
  • Music is then generated by allocating to each time interval a sound, the duration, tone and volume of which are determined by a parameter K extracted from the frequency spectrum.
  • This parameter K is equal to the ratio of spectral powers obtained over two separate frequency ranges.
  • Patent application EP-A-0 301 790 discloses techniques for detecting electrical signals generated in a human body, called
  • biopotentials and the transformation of such signals into a MIDI code.
  • Video games, musical or relaxation therapy (col. 4, I. 41 to col. 5, 1. 2) among others are included in the many applications of these methods. It is more specifically indicated that the body may react to the musical notes generated, by modifying brainwaves or heartbeats (col. 20, I. 6-9).
  • the frequency of a detected signal can be transformed into a note pitch (col. 8, I. 35-43), a program number or a harmonic generation (col. 11 , 1. 16-19), and a change in intensity or frequency can be transformed into a change in musical parameters (col. 8, I. 35-43).
  • a note pitch col. 8, I. 35-43
  • program number or a harmonic generation (col. 11 , 1. 16-19)
  • a change in intensity or frequency can be transformed into a change in musical parameters (col. 8, I. 35-43).
  • One example described in this document (col. 20, I.
  • 24-28 consists in modifying a MIDI code coming from another machine as a function of properties of measured biopotentials. It is thus mentioned by way of illustration that it is possible to increase the note pitches or to modify the rhythms when the heartbeats accelerate in an electrocardiogram signal (col. 20, I. 42-49).
  • the present invention relates to a system for producing music as a function of physiological parameters of a user, especially enabling heartbeats of the user to be controlled reliably during repetitive sporting efforts.
  • the system of the invention avoids the user himself assessing the frequency of a musical rhythm to know whether or not he has to moderate his efforts. It also enables him to avoid receiving confused information, further risking causing an error rather than helping him to measure the intensity of his activities.
  • the invention relates to a system for producing music as a function of physiological parameters having physiological rhythms, which makes it possible to obtain information which is reliable and which can be used directly on these physiological rhythms.
  • the invention is applicable not only to the control of repetitive sporting efforts (jogging, bodybuilding, gymnastics, etc.), but also to various other situations such as:
  • the invention also relates to a method of producing music as a function of physiological parameters and to a computer program, corresponding to the system of the invention.
  • the subject of the invention is a system for producing music as a function of physiological parameters, comprising:
  • the unit for producing music is such that the physiological rhythm is essentially represented in the music by the other musical parameters.
  • music produced refers to any music allowing variations of musical parameters. This music may especially consist of: - prerecorded music; for example, different recordings are allocated respectively to different ranges of values of the physiological rhythm;
  • a network for example on the air
  • channels broadcasting various types of music are associated with various ranges of values of the physiological rhythm.
  • physiological rhythm refers to any regular cadence likely to be extracted from the physiological parameters, for example a dominant frequency identified by Fourier transformation.
  • musical rhythm refers to the conventional concept of rhythm in the musical field, which is applicable to events whose succession in time is discernable to the ear, and not in particular to a vibration frequency creating a particular sound impression (note pitch) to a listener. Such a rhythm can be expressed as the succession and the relationship between audible values of particular durations.
  • the musical rhythm may especially consist of a tempo, that is to say of the rate of execution of a work.
  • the extraction of one or more physiological rhythms from one or more physiological parameters is obtained by any method, and may be based on a filtering technique and/or on a frequency transformation. In practice, it involves a dominant frequency (frequency peak) in the spectrum of the physiological parameter, representative of a periodic repetition. Similarly, the musical rhythm can be identified by a dominant frequency in the spectrum of the music produced (taking into account the restrictions above on the definition of the musical rhythm). According to variant embodiments, the system takes into account several physiological rhythms and/or several musical rhythms, it being possible for each of the physiological parameters to have one or more physiological rhythms.
  • the other musical parameters "represent" the physiological rhythm. They are therefore such that significant variations in the latter are perceptible in the music through these musical parameters.
  • the term "significant variations” refers to variations providing a benefit with respect to the desired result, for example unambiguously indicating that the cardiac activity is located either within an acceptable region, or warrants rest, or is dangerous.
  • This representation may optionally relate only to certain modifications of the physiological rhythm, for example to indicate exclusively the passage from a lower range to an upper range of values, by means of a binary selection between two values of the musical parameter in question.
  • this characteristic of "representation" of the physiological rhythm by a musical parameter is expressed as follows. It relates to the physiological parameter in a given measurement field of the physiological rhythm. In this measurement field, at least one value of the musical parameter in question is allocated to each value of the physiological rhythm.
  • This allocation may be deterministic, that is to say that since other data required independently of the physiological parameter are fixed (for example specific characteristics of the person on which the measurements are made), a single value of the musical parameter is allocated to the value of the physiological rhythm.
  • the allocation may also be nondeterministic, that is to say that several values of the musical parameter, which could include one or more ranges of values, are allocated to the same value of the physiological rhythm.
  • Such a nondeterministic allocation may be random, in which case the value effectively taken by the musical parameter from the various possible values for the value of the physiological rhythm is unpredictable. It may also be pseudo-random, when the value selected for the musical parameter is determined by an automatically selected parameter.
  • This selected parameter is, for example, derived from the physiological parameter, or from any mathematical law (such as loop selection of the various possible values of the musical parameter), or else from the present time.
  • the two types of allocation, deterministic and nondeterministic, may also be combined for the same musical parameter: in this case, the value of the musical parameter is one-to-one for some ranges of the measurement field, and indeterminate for others.
  • image of an interval of the measurement field refers to the set of possible values of the musical parameter in question (the other data required being fixed) for values of the physiological rhythm included within this interval.
  • Each image generally comprises at least one isolated value and/or at least one interval of values of the musical parameter, hereinafter called parametric value and parametric interval, respectively.
  • the musical parameter "represents” the physiological rhythm if the measurement field is divided into at least two intervals, hereinafter called rhythmic intervals, such that the respective images of these rhythmic intervals are separated in pairs by intervals of nonzero length.
  • Curve 71 corresponds to a random or pseudo-random distribution over two successive rhythmic intervals IR1 and IR2 forming a measurement field DM on one axis 60 of physiological rhythm RP.
  • the images of the rhythmic intervals IR1 and IR2 respectively consist of upper 1P1 and lower IP2 parametric intervals on one axis 61 of musical parameter PM, separated by an intermediate interval 74.
  • the discrimination may be effective even if the length of the intermediate interval 74 is short.
  • the uncertainties that would exist if the interval 74 was reduced to a point are avoided: the parametric intervals IP1 and 1P2 would then be adjacent at this point and, even if they were separate, there would be a risk of the values over the rhythmic intervals IR1 and IR2 tending toward the limiting value of this point until being unrecognizable by the listener.
  • the representativity of the musical parameter PM would then not be guaranteed.
  • Curve 72 defines a deterministic distribution of a musical parameter PM (axis 62) as a function of the physiological rhythm RP over the measurement field DM (axis 60).
  • the latter consists of three successive rhythmic intervals IR1 , IR2 and IR3, having three parametric values VP1 , VP2 and VP3 respectively (steps 75, 76 and 77, respectively) for images. Since these images are separated by intervals of nonzero length, the parameter PM represents the physiological rhythm RP. More specifically, it indicates whether this physiological rhythm RP has low (IR2), mean (IR3) or high (IR1) values.
  • Curve 73 corresponds to a nondeterministic distribution of a musical parameter PM (axis 63) over two successive rhythmic intervals IR1 and IR2 of the measurement field DM (axis 60).
  • the images of these intervals IR1 and IR2 consist of two parametric intervals IP1 and IP2, respectively, overlapping in a common region 78. Unlike the previous cases, the intervals IP1 and IP2 are therefore not separated by an interval, but have an intersection, the region 78.
  • the musical parameter PM is consequently unable to represent the physiological rhythm RP. This is because a user identifying values of the musical parameter PM would be unable to know whether the physiological rhythm RP were very high or very low.
  • the second point of this proposal is that the physiological rhythm is "essentially” represented by the other musical parameters. Recognition of the physiological rhythm is therefore not carried out fundamentally by the musical rhythm. Any effect of the physiological rhythm on the musical rhythm is incidental and does not have any meaningful purpose, other than secondary. When this effect is not completely removed, it may on the other hand allow a margin for maneuver in the production of music. This is therefore used either for artistic purposes, or to support the identification carried out by means of other musical parameters (for example, on crossing a threshold of the physiological rhythm, musical instruments are changed at a constant cadence thereby giving more rhythmic strength to a drum accompaniment).
  • the music production system of the invention contrasts with the known techniques highlighting variations of the physiological rhythm exclusively by means of varying the musical rhythm.
  • the physiological rhythm is perceived by means of other parameters, which may well be more discriminating to listen to, such as especially the nature of the music style or of the melody, instrumentation, scale, note pitch and/or the tonality.
  • the system of the invention also contrasts with known methods in which a variation of musical parameters, not restricted to the musical rhythm, is caused by modifications of the physiological parameter in question. This is because, in this case, the music production unit is such that these other musical parameters are representative of the physiological rhythm, and are not dependent on it only in a complex and unusable way.
  • the physiological rhythm is represented in a significant way in the music produced through musical parameters other than the musical rhythm.
  • the music production unit is such that this dependent contribution is minor in the musical rhythm.
  • This "contribution” is defined as the maximum amplitude of variation of the musical rhythm when the physiological rhythm sweeps the entire measurement field, all other specific characteristics of the physiological parameter in question moreover being the same.
  • This measurement field may cover the entire positive part of the real axis, or be more restricted for physiological reasons (for example, heartbeats are necessarily included within a physically feasible range of values).
  • This contribution is “minor” in the sense that the ratio of the contribution to the mean value of the musical rhythm over the measurement field is less than 50%.
  • the contribution of the physiological rhythm may in particular be zero, the musical rhythm then being completely independent of the physiological rhythm.
  • the user chooses a background musical rhythm, while the actual musical rhythm is given by a curve which increases as a function of the physiological rhythm over the measurement field, having a mean value equal to the background musical rhythm and an amplitude equal to 30% of this value, over this interval. Because of the existence of this limitation, the effect of the physiological rhythm on the musical rhythm is restricted. Thus, is it possible to avoid excessive disturbance of the latter by the former and, as a result, to enable a listener to be more receptive to the really meaningful variations in the music. This arrangement may also avoid drifts in rhythm which are disagreeable to listen to. It also makes it possible to select a given musical rhythm which is completely independent of the physiological rhythm and may therefore carry other information. In particular, this musical rhythm is advantageously employed to indicate the desired frequency of sporting efforts.
  • the contribution dependent on the physiological rhythm over this field is less than 20% of this mean, and preferably less than 10%.
  • the percentage of this contribution is calculated as indicated above.
  • the contribution of the musical rhythm dependent on the physiological rhythm is zero, such that the musical rhythm is independent of the physiological rhythm.
  • the musical rhythm is substantially constant over time. This constancy extends beyond the intervention of a user, likely to modify the musical rhythm.
  • the music production system then preferably comprises a unit for controlling the musical rhythm by a user, allowing this user to choose the musical rhythm which is substantially constant over time.
  • This embodiment may prove to be particularly useful for rhythmic sporting efforts. This is because it is then desirable to dissociate the cadence of effort, for example from walking, weightlifting or pedaling, from that of heartbeat.
  • the user has both this reference frequency and musical indications concerning his physical abilities.
  • the choice of the musical rhythm especially makes it possible to provide a pleasant rhythm, for example for a motor vehicle driver, or a lively rhythm, for example for music produced in a discotheque.
  • the latter can be varied over time.
  • rhythms in the music produced which makes it possible, for example, to choose various pieces without thinking about rhythms, or to introduce pleasant diversity, thus avoiding monotony.
  • the other musical parameters are advantageously chosen from styles of music (advantageously including at least one of the following harmonic families: western, eastern, far-eastern, blues, jazz, etc.), melodies, instrumentations (including, separately or in any combination: a choice of instruments or sounds, setting or "mixing" instruments relative to the parameters of overall volume, reverberation, echoes, panning, envelope, clarity of sound, etc.), scales, note pitches, tonalities, harmonic chords and any combination of these parameters.
  • a variation in sound intensity is also possible, but is secondarily rather than primarily desirable, because of the uncertainties in distinction by the listener and the uncomfortable consequences which could result from excessive sound variations.
  • physiological parameters they are advantageously chosen from heartbeats, an electroencephalogram, blood pressure, ocular pupil size, overall body movements, muscular tension (in particular quasi- static movement, such as a bodybuilding effort) and any combination of these parameters.
  • heartbeats an electroencephalogram
  • blood pressure a blood pressure
  • ocular pupil size a body movements
  • muscular tension in particular quasi- static movement, such as a bodybuilding effort
  • the physiological rhythm In a first form of deterministic relationship between the physiological rhythm and the other musical parameters, the latter depend on the physiological rhythm according to a dependence relationship which is continuous. A user may thus progressively notice a change in the music heard as a function of the physiological rhythm, which allows a subtle distinction. Furthermore, the transitions are thus pleasant to listen to.
  • the physiological rhythm In a second form of deterministic relationship between the physiological rhythm and the other musical parameters, the latter depend on the physiological rhythm according to a dependence relationship which is in steps.
  • This embodiment may allow the user to hear clearly significant transitions between several ranges of values of the physiological rhythm (for example, passing from an acceptable range to a dangerous range for sporting efforts).
  • the music production system advantageously comprises a unit for selecting a relationship of dependence of the other musical parameters on the physiological rhythm, from user information and reference dependence relationships stored in a database. It is thus possible to match the change in musical parameters to the specific characteristics of the user, such as his age, his sex, his height and his weight, etc. To do this, it is possible to resort to graphs giving appropriate curves.

  • the latter comprises:
  • the means of constructing at least one series of notes is such that, for each moment, each note whose pitch belongs exclusively to the second family is surrounded exclusively by notes from the first family.

  • the musical phrase generator 56 generates at least one succession of notes having at least two notes, each succession being constructed in such a way that, for each moment, each note whose pitch belongs exclusively to the second family is surrounded exclusively by notes of the first family.
  • a succession of notes is defined as a set of notes whose starting times are not separated from each other, in pairs, by more than a predetermined duration.
  • the generator 52 generating families of note pitches, for each half bar, a succession of notes does not have two consecutive note pitches which are exclusively in the second family of note pitches.
  • the output port 58 transmits, via the external signal line 59, a signal representative of the note pitches of each succession.

Abstract

La présente invention se rapporte à un système (1) et un procédé qui permettent de produire de la musique en fonction de paramètres physiologiques (PP), et à un programme informatique correspondant. Le système de l'invention comprend une unité (11) qui reçoit au moins un paramètre physiologique comportant au moins un rythme physiologique, et une unité (12) destinée à produire une musique comportant au moins un rythme musical (RM) et au moins un autre paramètre musical dépendant du rythme physiologique. Le rythme physiologique est essentiellement représenté dans la musique par les autres paramètres musicaux. De préférence, bien que le rythme musical comprenne une contribution dépendant du rythme physiologique, cette contribution est faible dans le rythme musical. L'invention trouve des applications dans la vigilance au cours d'activités sportives ou lors de la conduite de véhicules à moteur, et dans la création musicale par mouvements dynamiques ou quasi-statiques.
