  • the preferred embodiment of the present invention is a hand-held electronic musical instrument including at least one button-field and at least one motion sensor.
  • Button-Fields
  • each button-field is roughly the size of a single hand's span.
  • some embodiments of the present invention could place three octaves of buttons under a single hand's span. Two such button-fields — one for each hand — could therefore place six octaves of note-controlling buttons on an instrument that is little more than a single hand-span tall. This is almost as many octaves as the traditional piano keyboard's seven octaves, in an instrument that is smaller and therefore potentially lighter.
  • Figure 1 shows one possible embodiment of such a hand-held button-field instrument, presenting a separate button-field to each hand.
  • the small size and weight makes the preferred embodiment of the present invention easy to lift while playing, but nonetheless some means of support and stabilization may be necessary.
  • Using the player's digits to support the instrument interferes with their ability to interact with the instrument's controls. Therefore, a means of supporting the instrument that does not involve the player's digits would be preferred.
  • Back-of-the-hand straps as used in concertinas are certainly possible embodiments of such support means.
  • Such back-of-the-hand straps or braces leave the wrist free to rotate, but restrict movement of the fingers/hand over the button-field.
  • Neck or shoulder straps are also possible embodiments. While such neck or shoulder straps effectively shift the weight of the instrument away from the fingers/hands/arms, they do not stabilize the instrument firmly.
  • An accordion- style harness would both support and stabilise the instrument, at the cost of immobilizing it.
  • the present invention could be supported and stabilized by affixing it to a stand, such as a microphone stand, although this would also tend to limit its range of motion.
  • the present invention could be supported by a single rigid forearm brace, as shown in Figure 11 and Figure 12.
  • a single rigid forearm brace would both support and stabilize the instrument, freeing the player's hand/wrist to flex through a wider range of movement over the button-field than would a back-of-the-hand strap.
  • a single forearm brace would be used, coupled with a neck strap as shown in Figure 13 and Figure 14 or instrument stand (not shown) at the player's discretion, to and from which the instrument or brace could be attached or detached rapidly through various mechanical means.
  • the forearm brace could house some of the instrument's electronics, as shown in Figure 15 and Figure 16.
  • the brace's centre of mass is closer to the weight-bearing elbow than the instrument's button-fields. Any electronics, tone generators, batteries, displays, touch-screens, user interface devices, or other elements of the instrument's functionality that could be placed in the forearm brace rather than the button-field-containing portion, would make it easier to lift the instrument.
  • the upper and inner surfaces of such a forearm brace are generally visible to the player while playing and are certainly both visible and accessible in-between songs.
  • Another advantage of the forearm brace is that it can stabilise the instrument in a fixed position right in front of the digits of the arm to which it is attached.
  • the exact geometry of the instrument to the digits could be adjustable by mechanical means.
  • An alternative embodiment of the present invention could provide only a single button-field, devoting some or all of the digits of one hand to holding the instrument, the other digits of said one hand potentially operating musical effects controls such as but not limited to joysticks, dials, sliders, etc.
  • the instrument would include at least one motion-sensing electronic component, such as a solid-state linear accelerometer or gyroscope.
  • a solid-state linear accelerometer or gyroscope Such sensors are often combined into a single solid-state component including two, three, or even more such sensors.
  • Three-dimensional space is commonly defined using a Cartesian coordinate system of three orthogonal axes, conventionally named X, Y, and Z as shown in Figure 3.
  • Linear accelerometers measure acceleration along a single spatial axis
  • gyroscopes measure rotational velocity around a single spatial axis.
  • Given acceleration or velocity, integration or differentiation can yield position, velocity, or acceleration as desired.
  • Each of the three spatial axes thus has two components — linear acceleration and rotational velocity — yielding six independent variables, also called six "degrees of freedom.”
  • Each of the six independent variables thus has two other dependent variables. Any or all of these eighteen possible motion- derived variables can be made available from a six degree-of-freedom set of motion sensors.
  • One or more of these motion-derived variables could be processed to control musical effects such as timbre, pitch bend, vibrato, and so on.
  • translation along all three orthogonal axes of space, and the rotation around each, would be measured. Measuring translation alone is difficult, due to the need to compensate for the acceleration of gravity, If measurement of only a subset of the six degrees of freedom is desired — perhaps to reduce component cost — then measuring only rotation around all three axes without measuring translation is preferred.
  • motion can be an excellent means of controlling continuous musical effects, it is a very poor method of selecting pitches, which are discrete and need to be precisely in tune.
  • Motion sensors may reasonably control "pitch bend" (that being a variation in pitch for expressive effect), however.
  • Keyboard instruments excel at making it easy to select arbitrary combinations of a large number of notes simultaneously.
  • Keyboard synthesizers may offer many knobs, dials, switches, etc., for controlling musical synthesis variables, but relatively few of these variables can be conveniently adjusted while actually playing.
  • most keyboard synthesizers include a pitch bend control and a modulation (vibrato) control, allowing the control of those two variables — but one must stop playing accompaniment with the left hand, move that hand to the control wheels, and devote them to controlling those variables (singly or together) to add musical expression during a performance.
  • a hand-held button-field instrument including motion sensors can be quite small, light, and easily supported. It can provide all of the polyphonic benefits of a piano keyboard while also being easy to translate and rotate through space.
  • motion sensors within the body of (or affixed to the exterior of) the present invention up to eighteen motion-derived variables can be controlled simultaneously simply by translating and/or rotating the instrument through space.
  • button-fields makes the present invention so small and light that it can be moved and rotated through space easily while still providing polyphony — unlike conventional piano keyboards.
  • Figure 3 shows a player holding an embodiment of the present invention supported by a back-of-the-hand brace.
  • the player's right hand is held out of the way to simplify the drawing, although it could be placed to access the instrument's right-hand button-field (if any), with or without a right-hand back-of- the-hand or forearm brace.
  • the instrument shown in this and all subsequent figures is presumed to contain a full set of linear accelerometers and gyroscopes, such that movement along and around all three spatial axes is measured.
  • Figure 9 the player has rotated the instrument positively around the Z axis, away from its initial position as shown in Figure 3. This movement would be detected and reported by the instrument's Z-axis gyroscope.
  • Figure 10 shows a more complex motion, combining (a) translation upwards along the Z axis (+z), (b) translation towards the player's body along the Y axis (-y), and (c) rotation around the X axis (+pitch). These movements would be detected by the instrument's Z-axis accelerometer, Y axis accelerometer, and X-axis gyroscope, respectively. Thumb Controls
  • the player's thumbs need not stabilise or position the present invention, as they must do for concertinas — they are free for other duties.
  • One or more of the player's thumbs can be devoted to the manipulation of controls affecting musical effects, such as pitch bend, vibrato, overall volume, timbre, etc.
  • the controls could take the form of physical devices like joysticks, buttons, sliders, dials, and the like, some of which are shown in Figure 2.
  • they could take the form of virtual controls on a touch-sensitive display.
  • Yet another embodiment could contain some physical devices and some virtual controls. Muting and Resetting the Motion Controls
  • one embodiment of the present invention can be equipped with user-operable devices which "mute” and/or "un- mute” one, some, or all motion sensors. Muting a motion sensor suppresses its output, allowing the player to move freely along or around that sensor's axis without affecting musical expression.
  • the preferred embodiment of the present invention has a user-operable "reset button.” Resetting the motion sensor module establishes its current position as being the origin from which all subsequent motions are measured as deviations. Motion sensors may tend to "drift" in a time scale that may affect a musical performance. Just as a trumpet has a spit valve, the preferred embodiment's reset button may be used to "drain the drift" from its motion sensors, resetting their origin to the instrument's position when reset.
  • thumb controls can be included to selectively mute/unmute and/or reset individual motion sensors or combinations thereof.
  • Figure 17 shows a simple block diagram of the present invention's electronics.
  • Data regarding the state of the finger controls, thumb controls, and motion sensors all goes to a central processing unit.
  • This central processing unit may process this data through various algorithmic means familiar to those versed in the art of electronic music to emit MIDI.
  • This MIDI data could then be routed through standard cabling or wireless means to an external tone-generating unit or units (not shown) which would produce audio data based on the MIDI data stream.
  • the central processing unit may include a tone- generating unit and emit audio data without requiring an external tone-generating unit.
  • MIDI MIDI
  • the tone module would treat changes to a given MIDI variable the same way whether the changes were being controlled by a finger-operated button, a thumb-operated joystick, a motion sensor, or any other MIDI-compatible controller.
  • controller and tone-generator facilitates the development of a new controller such as an embodiment of the present invention, by allowing its adopters to leverage their existing investment in tone-generating equipment.
  • an external reference point can be Magnetic North, detected through use of a magnetic sensor.
  • an external device can be used to emit or reflect a signal which the present invention's sensors can use as a reference point.
  • Such external devices could include emitters of signals such as radio, infra-red, laser light, or other such signals known to those versed in the electronic arts.
  • Such an external device could be stand-alone, or integrated into a musical instrument's carrying-case, or attached to a microphone stand, or provided in a variety of other form-factors.
  • a complete music-making system comprises four logical units: a) a hand unit, including thumb controls (if any), at least one button- field, and at least one motion sensor either internally or externally affixed; b) a tone-generation unit, which may be incorporated into the hand unit or reside in a separate unit, the two being connected by wired or wireless means; c) a speaker or headphone unit, which may include a tone-generation unit, an amplifier, user-interface elements, etc., d) possibly incorporated into a carrying-case for the other portions; e) optionally, an instrument support system such as a forearm brace or back-of-the-hand brace, which may include the tone-generation unit and/or other elements of the system's functionality; f) optionally, a heading-indicating signal emitter.
  • a hand unit including thumb controls (if any), at least one button- field, and at least one motion sensor either internally or externally affixed
  • a tone-generation unit which may be incorporated into the hand
