Described herein are embodiments of sensorized spherical input and output devices, systems, and methods for capturing gestural input from a user's physical interactions with a spherical device, including tossing, bouncing and spinning. In one embodiment, the spherical input and output device includes force sensors in a configuration to capture a variety of user gestures with the sphere. A microprocessor receives sensor input and transmits the sensor data to receiving devices which include computer software to translate the sensor signals to audio output, visual output, or various functions on receiving devices. Embodiments of the invention include the integration of inertial measurement units (IMUs), which may include a combination of accelerometers, gyroscopes and magnetometers to capture complex user gestures involving motion, direction and spin of the sensorized sphere in three dimensional space.

Method of teaching a vocal harmony involves a computing device which automatically generates a plurality of audio presentations of a musical composition in a predetermined series. Each audio presentation in the series is different from the other audio presentations in the series and is configured to assist the user in progressively learning the selected vocal harmony part. Each of the plurality of audio presentations in the predetermined series is made different from others of the audio presentation in the predetermined series by selectively controlling (1) the particular ones of the plurality of vocal harmony parts that are included in each of the audio presentations, and/or (2) a magnitude of an audio volume that is applied to each of the plurality of vocal harmony parts that is included in each of the audio presentations.

A music learning aid, comprising: a first rotatable circular substrate having a radius (R1) comprising an in-use first visible circular scale displayed on the first substrate, the visible display comprising a plurality of indicia for indicating corresponding musical notes such that the musical notes indicated in the visible display scale ascend in frequency in a clock-wise or anti-clockwise direction; a second circular substrate having a radius (R3), the second substrate being arranged to be substantially concentric and rotatable relative to the first substrate by the fastening arrangement to enable the second substrate to rotate relative to the first substrates, the second substrate comprising a polygon with vertices of the polygon being located along the circumference of the second substrate, the second substrate comprising respective indicia corresponding to each of the vertices for indicating a respective musical mode selected from a set of a plurality of musical modes.

Methods and systems of music notation for visually representing music that provide a visual scale representing a range of an auditory scale of a portion of a musical composition spanning at least four and a half steps. The visual scale may comprise a plurality of whole-step segments each representing one whole step in the auditory scale. Each whole-step segment may be approximately a first height. The visual scale may also comprise one or more half-step segments each representing one half step in the auditory scale. Each half-step segment may be approximately a second height. A first ratio representing the first height divided by the second height may be significantly greater than a second ratio representing the whole step divided by the half step.

A plurality of first sensory cues are generated capable of being perceived by a user. Each first sensory cue of the plurality of first sensory cues is dependent on a position of at least one body member of a performer relative to a performance element of a performance object with which an event is performed. The plurality of first sensory cues being effective for stimulating a first processing center of a brain of the user. A plurality of visual sensory cues are generated capable of being displayed to the user on a video display device. The visual sensory cues providing a virtual visual indication to the user of the position of the at least one body member. The visual sensory cues being effective for stimulating the visual processing center of the brain of the user. The visual sensory cues being synchronized with the first sensory cues so that the position of the at least one body member is virtually visually indicated in synchronization with the first sensory cue and so that the visual processing center is stimulated with a visual sensory cue in synchronization with a first sensory cue stimulating the first processing center. The synchronized stimulation of the first processing center and the visual processing center is effective for teaching the user to perform a version of the event.

A simulated musical string instrument formed of plural shaped sheets of rigid material, such as cardboard. There is a top sheet forming a top surface of the simulated string instrument body, and a bottom sheet forming a bottom surface, and multiple sheets between. A simulated fingerboard is attached to the top surface. The top sheet and fingerboard gets stickers that show parts of the simulated string instrument body including openings and notes. There is also a simulated bow guide and a simulated bow.
